Group Policies Alert Configuration Policies Sending Alerts to the HP TopTools Management Station When you check this box, all alerts will be sent to the HP TopTools Server in addition to any other trap receivers that you have designated. This feature is enabled by default. Removing Trap Receivers If the Remove trap receivers not listed below check box is checked, any trap receivers configured that are not displayed in the trap receivers list box will be removed as trap receivers. Figure 7-7.
Group Policies Advanced Switch Features Low Sensitivity: The device will make an entry in the Alert Log only when severe network problems occur. These are problems that may bring the network down. Off: The device will never make any entries in the Alert Log regardless of the severity of the problem. : The current value stored in the switch is not modified If you make any changes, you must click on Apply Policies in the main Configuration Policies page for your changes to take effect.
Group Policies Advanced Switch Features Figure 7-8. Advanced Switch Features Page The problem of broadcast control is addressed in part by the use of two features, Automatic Broadcast Control (ABC) and Internet Group Management Protocol (IGMP). Automatic Broadcast Control (ABC) Automatic Broadcast Control (ABC) is a feature that controls broadcasts through IP/IPX Broadcast Reduction. IP/IPX Broadcast Reduction reduces the number of broadcasts propagated through the network.
Group Policies Advanced Switch Features Routing Information Protocol The switch also intercepts Routing Information Protocol (RIP) and SAP broadcasts and forwards these only to ports where routers and servers have been detected. This also reduces the number of broadcasts on the network. For example, if User A sends out a broadcast message to connect to its server, the request is sent out of all ports on the switch.
Group Policies Advanced Switch Features Automatic IPX RIP/SAP Control To further reduce network traffic, you can check the Automatic IPX RIP/SAP Control check box. The switch will intercept RIPs and SAPs, broadcasting them only to ports where IPX routers or servers have been detected, or to ports that have been configured to transmit RIPs or SAPs. When this feature is not enabled, IPX RIP/SAP packets are forwarded to all ports.
Group Policies Security Configuration Policies Special multicast routers/queriers communicate by using three message types - query, report, and leave group. The query message, sent by a querier, is used to discover which network interfaces belong to a multicast group. Each host responds to the query message with a report message that tells the querier the host is a member of the multicast group. The host also can send a report message to join a group or a leave message to leave a group.
Group Policies Security Configuration Policies ■ Discovery—Enables a device to be discovered by HP Toptools for Hubs and Switches for mapping in a Topology view.

9 Monitoring Network Traffic This chapter describes the tools for monitoring your network using Traffic Monitor. It contains the following topics: ■ Using Traffic Monitor ■ Reading the Segment Histogram ■ Setting Thresholds ■ Displaying the Network Meter ■ Who Are the Top 5 Talkers? ■ The Traffic Data Collector ■ Troubleshooting Traffic Monitor Using Traffic Monitor The Traffic Monitor presents real-time information about the status of your network.
Monitoring Network Traffic Using Traffic Monitor Figure 9-1. Traffic Monitor Main Page The five statistical attributes sampled by Traffic Monitor are: Utilization%: Represents the traffic on the selected network or segment as a percentage of a segment's bandwidth (based on the theoretical maximum for the type of connection) which is currently being utilized. Monitoring the utilization gives a measure of how much of the network capacity is being used on a particular segment.
Monitoring Network Traffic Using Traffic Monitor Multicasts/sec: Represents the number of multicast packets being transmitted per second over the network or segment. Multicast packets are special forms of broadcast packets where copies of the packets are delivered to a subset of all devices on the network. This indicator gives an estimation of the amount of bulk communications which are taking place over the network.
Monitoring Network Traffic Using Traffic Monitor The six tabs across the top of the histogram display the values for the segments for the selected segment group, or for the entire network if “All Segments” is selected in the Segment Groups list box. The Worst Overall tab displays in sorted order left to right the segments that have the most problems in the selected segment group.
Monitoring Network Traffic Using Traffic Monitor segments are trunked. This will not be visible in the Thresholds window. For example, if four ports on a switch are trunked, a 10 Mbps Ethernet segment would now be four times as fast, or 40 Mbps. The threshold values are adjusted automatically to be appropriate for this speed. You can still set the threshold values for a specific segment by selecting that segment from the list in the Segments tab. Figure 9-2.
Monitoring Network Traffic Using Traffic Monitor To change your threshold settings, select a network type such as Ethernet. The threshold values for the attributes for Ethernet segments are displayed. You can either move the sliders to the left or right to increase or decrease a threshold value, or click on the up/down controls underneath the sliders to fine tune the threshold values. As you move the sliders, these values will change accordingly.
Monitoring Network Traffic Who Are the Top 5 Talkers? You can keep the Network Meter window anywhere on your PC desktop. It will continue to monitor the status of your network while you use your browser for other tasks. Click on Hide Net Meter to close the window. When you close your browser, the Network Meter will also close. Options Button Clicking on the Options button at the bottom of the Traffic Monitor page displays the Link Gauges to selected segment in histogram check box.
Monitoring Network Traffic Who Are the Top 5 Talkers? Figure 9-3. Top 5 Talkers You can display graphs for each of the measured attributes showing: ■ Top Sources (default) ■ Top Destinations ■ Top Connections ■ Top Protocols More than one graph can be displayed at a time, so you can look at the values for multiple attributes for each segment. Since Traffic Monitor presents real-time information, the data will be “moving” on your graph. Data is graphed and updated every minute.
Monitoring Network Traffic Who Are the Top 5 Talkers? The colors are in the same order as they appear in the legend, that is, the node with the greatest activity is represented by the color at the bottom of the stacked bar. The white portion of the stacked bar represents the top talkers in minutes who are not top talkers in the selected minute; the dark gray portion of the stacked bar represents all other activity.
Monitoring Network Traffic Who Are the Top 5 Talkers? Others The dark gray portion of the stacked bar represents a summation of all of the other activity that occurred during that minute. There is no additional information contained in this portion of the bar. It can be a useful indicator of an overloaded network when what you see on the graph is large areas of dark gray with no particular user causing a problem.
Monitoring Network Traffic Traffic Data Collector Settings The located end node or segment will be highlighted in royal blue in the topology map. Traffic Data Collector Settings Starting with HP TopTools for Hubs & Switches version 5, you can collect data from all segments in your network automatically, or collect data from selected ports of a device (manual mode). With manual selection, you can also choose the type of data to be collected, for example, Extended RMON (X-RMON) data or just traffic data.
Monitoring Network Traffic Traffic Data Collector Settings Figure 9-4. Traffic Data Collector Configuration Page Nothing is displayed in the Traffic Data Manual Configuration table if Use Discovery/Topology Data (Automatic) is checked. Automatic Monitoring If you want to enable Automatic monitoring, check the radio button labeled Use Discovery/Topology Data (Automatic). The Traffic Data Manual Configuration table will be removed and manual selection disabled.
Monitoring Network Traffic Traffic Data Collector Settings Adding Ports for Manual Monitoring When you select the Add Devices button, the Add Devices dialog box displays a list of devices that are not being monitored. This list is comprised of devices discovered during the Discovery process and any devices added manually (Settings -> Discovery -> Additional Devices). Discovery (but not Topology) must have run before any devices can be added.
Monitoring Network Traffic Traffic Data Collector Settings Traffic Data Storage You can specify some criteria to control how much data is collected. Select Traffic Data Collector Settings from the Performance button in the navigation frame, then select the Storage tab. Your current settings are displayed in the Current Storage Status on Server area.
Monitoring Network Traffic Traffic Data Collector Settings Traffic Data Collector Performance You can specify the amount of system resources that the data collector can use. A more detailed network analysis requires more availability of system resources. The selections are: ■ High Resource Availability—Recommended for systems dedicated to network management. ■ Medium Resource Availability—Recommended for systems that run other less performance-sensitive applications.
Monitoring Network Traffic Troubleshooting Traffic Monitor Figure 9-6. Traffic Data Collector - Performance Page The data collector must examine your management station’s capabilities to determine what is appropriate for the resource setting that you select. The capabilities test begins when you click on the Apply changes button. You will see a screen listing some statistics about the test.
Monitoring Network Traffic Troubleshooting Traffic Monitor ■ Too Little Traffic on Network—If your network is carrying very little traffic at this time, the gauges will not indicate any traffic. ■ One Segment is Gray—There may be a problem with this particular segment. The data sampler may not be working, there may not be enough traffic on that segment, or a device may have been disconnected from that segment. ■ Machine is Very Busy—The CPU may not be able to process the data because it is too busy.

Planning for Network Growth Planning with the Network Performance Advisor Using Network Tools Current network analysis tools provide data about network activity in tabular or graphic form that must be laboriously analyzed and interpreted by a knowledgeable system administrator. This approach is time-consuming and does not provide the proactive analysis that allows for future planning. System administrators require tools that analyze data and present it in an easily understood format.
Planning for Network Growth Starting the Network Performance Advisor ■ Include Inventory in Report—creates a listing of your end nodes by segment. Use the Modify Report Settings page in the How to Improve Performance tab. The reports are HTML documents and must be viewed with a frames-capable browser such as Microsoft Internet Explorer (MSIE) 4.01 or later. For information on how to interpret the display, see “How to Interpret this Report” in each report’s Table of Contents.

When the report completes successfully, information about the report execution, including any errors that occurred, is displayed in the Summary page of the report. Viewing a Report To view a report, click on the Explore Reports tab and select a report from the list. The reports are listed chronologically with the most recent report at the top of the list.
Planning for Network Growth Starting the Network Performance Advisor Characteristic Description Number of Requested Hours with Data Available The actual number of hours that have data available. This is used with the Number of Hours Requested to obtain the Data Availability. For example, if you requested 10 hours of data, but two of the hours in the time period requested had no data, the Data Availability would be 80%. Networks Analyzed Data was collected by HP TopTools for the networks listed here.
Planning for Network Growth Reorganize Your Current Equipment Figure 10-4. Summary Report A priority of low, medium or high is given to help you determine the urgency of each recommendation. The priorities are defined as follows: ■ Low: Implementing this recommendation will result in a small reduction in network utilization. A low priority recommendation may be regarded as advance warning of a marginal condition on the network.
Planning for Network Growth Reorganize Your Current Equipment Recommendation Details Section The Recommendation Details section of the report supplies the supporting information for the recommendations made by the Network Performance Advisor. It includes a textual explanation and the “before” and “after” graphical representations of the affected network. The recommendations are in priority order, starting with High Priority.
Planning for Network Growth Reorganize Your Current Equipment Figure 10-6. The traffic pattern after implementing reorganization recommendations The network utilization for switch segment 10.4.12.10::B4 is reduced. The network utilization on switch segment 10.4.12.10::B3 is unchanged. It is recommended that you run this type of report before the Add or Upgrade Equipment report to obtain recommendations for reorganizing your existing equipment.
Planning for Network Growth Add or Upgrade Equipment you must decide if you want the new port to be a member of the VLAN if it isn’t already. For example, if a node is on Port 1 in VLAN A, and you move the node to Port 6, you may want to include Port 6 in VLAN A. How the Data is Analyzed The Network Performance Advisor analyzes historical traffic data for the time period specified to determine which nodes on the network converse.
Planning for Network Growth Add or Upgrade Equipment Figure 10-7.
Planning for Network Growth Add or Upgrade Equipment Figure 10-8. The Traffic Pattern after Dividing into Workgroups A table shows the nodes included in each workgroup, the projected utilization of the workgroup, and the recommended segment bandwidth for each workgroup. The Network Performance Advisor analyzes segments that have historical traffic data exceeding a maximum threshold to determine how to create separate workgroups that would reduce utilization.
Planning for Network Growth Top Conversations Converting Segments to Desktop Switching If a workgroup has high network utilization and cannot be divided, the Network Performance Advisor may recommend converting the segment’s topology to desktop switching, giving each node a dedicated port.When two nodes need to exchange data, the switch makes a connection with the dedicated segments of each node. Extraneous traffic to the nodes is eliminated and each node uses the full capacity of the network.
Planning for Network Growth Top Conversations The right column of the table shows the percent that this conversation contributed to the total traffic on this segment. Possible reasons that a conversation may not be listed in the table when a conversation has occurred on the segment are: ■ The conversation was not in the top number of conversations (for example, the Top 10 conversations) selected for display for each segment ■ One end of the conversation is a device (hub, switch or router).
Planning for Network Growth Inventory of End Nodes Inventory of End Nodes The Inventory section shows the end nodes for each segment with the IP address, IPX address, and MAC address for each node. The table is in alphabetical order by “Friendly Name”. This section only appears if you have checked it in the Modify Report Settings page (checked by default). Click on a segment in the Table of Contents frame to jump to the table listing the end nodes for that segment.
Planning for Network Growth When There Are No Recommendations When There Are No Recommendations If the Add and Upgrade Equipment Report determines that, based on the historical data for the time period you specified, there are no advantageous ways to optimize the network, the Summary section of the report states that there are no recommendations for changes to your network configuration at this time.
Planning for Network Growth How the Network Performance Advisor Collects Data Figure 10-11.The Traffic Data Collector - Storage Settings Page Note To stop data collection, you must stop all of the HP TopTools services. Go to the Settings tab in the home page and select TopTools Services. On the Services page click on the Stop Services button.
Planning for Network Growth How the Network Performance Advisor Collects Data Keeping the historical data about each conversation on a network requires a large amount of disk space. HP has developed a patented technique for greatly reducing the amount of data collected by using a statistical sampling of network traffic.
Planning for Network Growth How the Network Performance Advisor Collects Data Figure 10-12. The data collector must examine your management station’s capabilities to determine what is appropriate for the resource setting that you select. The capabilities test begins when you click on the Apply Changes button. You will see a screen listing some statistics about the test.
Planning for Network Growth Segments Excluded from Analysis Segments Excluded from Analysis Analysis of network traffic is possible for all segments with HP devices attached to them that have Extended RMON sampling capability, but may be performed for only a subset of the segments. This strategy best utilizes system resources for gathering information about the segments most likely to have traffic flow problems.
11 Quality of Service This chapter discusses the benefits of the Quality of Service features available in HP TopTools for Hubs & Switches.
Quality of Service Overview Note ■ HP Procurve Switch 8000M ■ HP Procurve Routing Switch 9308M and 9304M ■ HP Procurve Routing Switch 6308M-SX and 6208M-SX The Quality of Service features available in HP TopTools for Hubs & Switches includes the ability to set up consistent traffic prioritization (Class of Service) policies across the Procurve switches in your network. The Class of Service features can also be configured on an individual switch using the switch's console or web browser interface.
Quality of Service Basic Operation Basic Operation HP TopTools QoS operates on two levels as described below. Controlling the priority of outbound packets. Procurve switch ports have two outbound traffic queues; “normal” priority and “high” priority. High-priority packets leave a port first. Normal-priority packets leave the port after the port’s high-priority queue is emptied.

The Class of Service features can also be configured on an individual switch using the switch's console or web browser interface.
Managing Switches Configuring Switch Features ■ Override “illegal” packet priorities set by upstream devices or applications that use 802.1Q VLAN tagging with 802.1p priority tags. ■ Avoid or delay the need to add higher-cost NICs (network interface cards) to implement prioritizing. Instead, control priority through network policy administered by HP TopTools for Hubs & Switches. Definitions The following terms are used frequently with policy configuration.
Managing Switches Configuring Switch Features the “normal” outbound port queues. However, with a CoS policy operating in your network, you can determine the outbound priority queue to which a packet is sent. Policy Options for Extending Traffic Priority Control to Outbound Packets Traveling to Downstream Devices. If an outbound packet is in an 802.1Q tagged VLAN environment, that is, if the packet is assigned to a tagged VLAN on the outbound port, then the packet carries an 802.
Managing Switches Configuring Switch Features ■ The priority queue assignment that the packet will receive in a downstream device that uses 802.1p priority settings. Table 13-4. Priority Mapping Table Priority Policy Set in HP TopTools Outbound Port Queue in the Procurve Switches 802.
Managing Switches Configuring Switch Features Guidelines for Configuring CoS Priorities Using CoS in a tagged VLAN environment controls the following: ■ Outbound port queue—The queue to which a high or normal packet will be sent ■ Outbound 802.1p priority—The new 802.1p priority setting in an outbound packet or the packet’s existing 802.1p setting. This enables the packet to carry an 802.1p priority to the next downstream device.
Managing Switches Configuring Switch Features 3 Protocol Priority The switch can prioritize outbound packets for one or more of these network protocols: IP, IPX, ARP, DECNet, AppleTalk, SNA, and NetBEUI. Default state: No override for any protocol. If a packet does not meet the criteria for Protocol priority, then precedence defaults to VLAN criteria, below. 4 VLAN Priority Enables packet priority based on the name of the VLAN in which the packet exists.
Managing Switches Configuring Switch Features Figure 13-9. Monitoring Selected Ports on a Switch Setting Device Features The Device Features page (only found on switches) lets you set some or all of these features: ■ Automatic Broadcast Control (ABC)—ABC reduces the number of broadcasts propagated through the network. See Automatic Broadcast Control for further discussion of this feature.
Managing Switches Configuring Switch Features Figure 13-10.Switch Device Features Page If you have configured VLANs for the switch (you must do this with the device console), select a VLAN for which the features will apply. Note It is recommended that you use the Group Policies feature (accessed in the Top Tools for Hubs & Switches home page) to set these features for all your switches. Setting features individually, for example, Spanning Tree, could create problems with your network.
Managing Switches Configuring Switch Features Additional header for the Commander of a stack Stacking button Figure 13-11.Configuration Page for HP 8000M as Commander of a Stack Stacking allows the configuration of a group of switches so that they appear as one unit with one IP address. This provides a single point of IP management for all switches in the stack and allows the configuration of multiple ports or switches at one time.
Managing Switches Configuring Switch Features Stack Management with VLANs You can use stacks in a VLAN environment. Each switch in the stack (Commander and Members) uses only the default VLAN configured in that switch for stack links. In the Web browser interface, this is the VLAN labeled Default . All VLANs in the stack need to be interconnected through the default VLAN. The VLAN ID for the default VLAN must be the same for all switches in the stack.
Managing Switches Configuring Switch Features ■ Providing an easy, flexible, less costly way to modify logical groups in changing environments ■ Preserving current investment in equipment and cabling ■ Allowing administrators to “fine tune” the network ■ Providing independence from the physical topology of the network If an HP switch has been updated to software release C.08.xx, you can configure VLANs with the Web browser.
Managing Switches Configuring Switch Features 4. Confirm removal of the VLAN. Modifying Port VLAN Configuration There are three modes a port in a VLAN can be in: ■ Tagged—When a port is tagged, it allows communication among the different VLANs to which it is assigned. ■ Untagged—When a port is untagged, it can only be a member on one VLAN. ■ No—the port is not a member of that VLAN.

14 Setting Up Security for a Device It is advisable to set up security for your devices to prevent unauthorized access to the device or the network. You can configure device security to prevent unauthorized use of certain parts of the network by certain nodes, and to keep unwanted traffic out of certain parts of the network.
Setting Up Security for a Device Device Passwords Figure 14-1. Device Passwords Page There are two categories of passwords: ■ Operator (Read only)—The Operator can view all pages except the Security pages. For switches, this password is the same as the console password. ■ Manager (Full Read and Write permissions)—The Manager can view all pages and make any changes in any page.
Setting Up Security for a Device Device Passwords Table 14-1. Password Settings Passwords Read Protected Write Protected Results Manager password set Operator password not set N/A Yes Anyone can get Read Access, but only the Manager can read and write to the device. Recommended minimum setting. Manager password set Operator password set Yes Yes Both the Manager and the Operator have Read Access, but only the Manager has Write Access. Everyone else is shut out of the device. Recommended setting.
Setting Up Security for a Device Device Passwords Figure 14-2. Set SNMP Community Names Page A device must have a community name of “public” to be identified by HP TopTools for Hubs & Switches. If a device does not have a community name of “public”, it will be discovered but not identified. For HP bridges and older hubs (See Note 1) there is only one community name, which has both “read” and “write” access. The “public” community name exists, but is hidden. It has “read” access.
Setting Up Security for a Device Device Passwords 2. Select “SNMP Communities...”. 3. For the “read” Community, set MIB View = Operator; Write Access = Restricted. 4. For the “write” Community, set MIB View = Manager; Write Access = Unrestricted. For greater security you can specify the addresses of those stations from which SNMP requests are allowed. These addresses are specified in the list of Authorized Managers associated with each community name.
Setting Up Security for a Device Hub Port Security All of the features of HP TopTools for Hubs & Switches should now work correctly for all devices, with the following exceptions: 1. The topology of some older devices may not display correctly. 2. The Update Firmware... option may not work. 3. The Closeup View for devices J3100A, J3125A, J3175A, and J3177A cannot be invoked. 4. The SNMP Trap Configuration option in the Devices page will not work.
Setting Up Security for a Device Hub Port Security Figure 14-3. Hub Port Security Page Address Selection Address Selection refers to how the authorized address for a port is discovered. The three settings are explained in the table. Table 14-2. How Authorized Addresses are Discovered Setting Description Continuous The device learns the address of the device attached to the port and makes it the authorized MAC address.
Setting Up Security for a Device Hub Port Security Authorized Address The Authorized Address field contains the MAC address of the device that is authorized to be attached to the port. Eavesdrop Prevention Eavesdrop Prevention is a feature of several HP devices that stops a computer or other device from seeing network traffic that is not intended for that port.
Setting Up Security for a Device Setting Security Policy for Selected Ports Figure 14-4. Setting the Thresholds for Trap Receivers Disable Port If the Disable Port parameter displays yes, the port may be disabled when an unrecognized address is received. Disabling the port depends on the Address Selection parameter that you have chosen. The settings First Heard and Assigned will disable the port if a new address is heard on that port.
Setting Up Security for a Device The Hub Intrusion Log Figure 14-5. Setting the Security Policy for Selected Ports The Hub Intrusion Log The Intrusion Log page lets you view security intrusions (violations) of a device. The information displayed includes: 14-10 ■ Port—The ports that have detected attempts of unauthorized access. ■ Intruder Address—The address of the intruder. The IP address is displayed for SNMP agent violations. The MAC address is displayed for port violations.
Setting Up Security for a Device Switch Port Security Figure 14-6. Hub Intrusion Log Switch Port Security Using Port Security, you can configure each switch port with a unique list of the MAC addresses of devices that are authorized to access the network through that port. This enables individual ports to detect, prevent, and log attempts by unauthorized devices to communicate through the switch. Basic Operation The default port security setting for each port is off.
Setting Up Security for a Device Switch Port Security ■ Note • Automatically sends notice of an attempted security violation to the switch's Intrusion Log and to the Alert Log in the switch's web browser interface. • Sends an SNMP trap notifying of an attempted security violation to a network management station. For more information on configuring the switch for SNMP management, see the Management and Configuration Guide you received with the switch.
Setting Up Security for a Device Switch Port Security Parameter Description Learn Mode Specifies how the port will acquire its list of authorized addresses. Continuous (the default): Allows the port to learn addresses from inbound traffic from any device(s) to which it is connected. In this state, the port accepts as authorized any device(s) to which it is connected.
Setting Up Security for a Device Switch Port Security Parameter Description Authorized Address Appears when Learn Mode is set to Static. Enables you to enter up to eight authorized devices (MAC addresses) per port, depending on the value specified in the Address Limits field. If you enter fewer devices than you specified in the Address Limits field, the port learns the remaining addresses from the inbound traffic it receives.
Setting Up Security for a Device Switch Port Security Access Levels For each authorized manager address, you can configure either one of these access levels: ■ Manager—Enables full access to all web browser and console interface screens for viewing, configuration, and all other operations available in these interfaces ■ Operator—Allows view-only access from the web browser and console interfaces.
Setting Up Security for a Device Switch Port Security Note The IP Mask is a method for recognizing whether a given IP address is authorized for management access to the switch. This mask serves a different purpose than IP subnet masks and is applied in a different manner. Figure 14-7. Switch Authorized Addresses List To configure IP Authorized Managers: 1. Select the Authorized Addresses button in the Security screen. 2. Enter an Authorized Manager IP address. 3. Select an Access Level. 4.

A Appendix A Appendix A contains the following topics: ■ Agent Firmware Versions ■ Preparing Network Devices ■ Globally Assigned IP Network Addresses ■ Configuring IP Parameters Agent Firmware Versions HP TopTools for Hubs & Switches communicates with network devices using SNMP (Simple Network Management Protocol). For HP TopTools to access device features, each network device must contain a compatible version of agent software or firmware.
Appendix A Preparing Network Devices Note HP TopTools for Hubs & Switches may be able to discover devices that have previous versions of device agent firmware. However, the use of some functions may be limited. Preparing Network Devices For HP TopTools for Hubs & Switches to communicate with devices on your network, the network devices must: Note ■ have SNMP agent firmware that is compatible with this version of HP TopTools. ■ for IP networks, have a unique IP network address.
Appendix A Configuring IP Parameters Globally Assigned IP Network Addresses If you intend to connect your network to other networks that use globally administered IP addresses, Hewlett-Packard strongly recommends that you use IP addresses that have been assigned to you. There is a formal process for assigning unique IP addresses to networks worldwide. Contact one of the following companies: United States and countries not in Europe or Asia/Pacific Network Solutions, Inc.
Appendix A Configuring IP Parameters Note: Make sure that every device has a unique IP address. Make sure that all devices on a given IP network number have the same subnet mask. The IP configuration parameters are described below. IP Address . The IP address of the hub, bridge, or switch is written in the format X.X.X.X, where each X is a decimal number between 1 and 254. Every IP address on a network must be unique. The default value, 0.0.0.0, disables IP communications.
Appendix A Configuring IP Parameters Network Bootp Server HP EtherTwist Hub Plus/24S and HP AdvanceStack 10Base-T hubs (with SNMP modules installed) support the use of Bootp (Bootstrap Protocol) to automatically retrieve their IP configuration from a server on the network. A device's IP configuration must be configured in a file on the Bootp server. When the device is powered on, Bootp is used to automatically download the IP configuration to the device.
