1 0 W EB - BASED N ETWORK M ANAGEMENT Introduction The content of this user’s guide pertains to intelligent (management) Hub models only. An embedded web-based (hypertext) interface allows users to manage the switch from anywhere on the network through a standard browser such as Netscape Navigator/Communicator or Microsoft Internet Explorer. The web-browser acts as a universal access tool and can communicate directly, with the Hub, using HTTP protocol.
Dual-Speed Stackable Hub Web-based Management User’s Guide The second and last step is to configure the IP interface, of the Hub, through console management. See the In-Band Setup Instructions on page 39 to do this. Management Your Hub has a hypertext interface, allowing you to do management through your browser. Your web-browser screen may vary with the screen-shots (pictures) in this guide. Configuration Hub configuration settings can be set via the web-browser. These options are described below.
The Hub information is described as follows: ♦ System Description A description of the hub type. ♦ System OID The SNMP Object Identifier for this hub type. ♦ System Uptime The amount of time that the hub stack has been powered on. ♦ System Contact User-defined information for the physical location of the hub. ♦ System Name A user-assigned name for the hub. ♦ System Location A user-assigned description for the physical location of the hub. ♦ Runtime Software Version software.
Dual-Speed Stackable Hub Web-based Management User’s Guide The information is described as follows: ♦ IP Address The Internet address for the device. ♦ Subnet Mask The subnet mask determines the level of the subnet that the hub is on. ♦ Default Gateway The default router for the device. ♦ MAC Address The physical address for the device. ♦ Interface Type The media protocol. Trap Receivers Defining a Trap Receivers allows network management stations to be notified when exceptional events happen.
♦ Community traps. ♦ Delete This will remove a trap receiver from the trap receiving table. This is the SNMP community name to authenticate the receiving of Software Download The Software Download screen allows you to cause an immediate update of the hub’s parameters and/ or firmware. The fields are described as follows: ♦ Software Update Mode Set to either network or out-of-band. Determines whether the configuration file should be obtained through the Ethernet network or through the console port.
Dual-Speed Stackable Hub Web-based Management User’s Guide ♦ Boot Server Address configuration file is located. ♦ Boot Protocol Set to either bootp-tftp or tftp only. Applies only if the Software Update Control is enabled. ♦ Get IP From Bootp Server BOOTP server. The IP address of the TFTP server where the If enabled, the address will be obtained from the SNMP Manager Configuration The SNMP Manager Configuration screen allows you to define community strings and access privileges.
Control The operations described in this section allow you to manage the Hub while it is operating. Group/ Port and Console Control Click Fault → Group/Port Control to show the Group/Port Configuration Control screen. Hub (group), port, and console configurations can be easily selected from this screen. Simply, click the particular component you want to view or modify.
Dual-Speed Stackable Hub Web-based Management User’s Guide The information is described as follows: ♦ Current Serial Port Setting Out-of-band. ♦ System Restart Serial Port Setting Out-of-band management upon reboot. ♦ Baud Rate This is cps (characters per second) of the information exchange between the Hub and it’s console manager. ♦ Character Size This is the number of bits in the byte unit of the information exchange between Hub and console manager.
Group (Hub) Configuration Clicking Fault → Group/Port Control → [Hub ID] will show the current configuration information of the Hub. The information is described as follows: ♦ Serial Number This is a unique hardware serial number of the Hub. ♦ Description This is the product ID. ♦ Slot 1/ Slot 2 Type of the Hub. ♦ Repeater Type Product information of the Hub. ♦ Group Role The role of the Hub within the stack, either primary-master, backup-master, or slave. ♦ Hardware Revision Hub.
Dual-Speed Stackable Hub Web-based Management User’s Guide ♦ Isolated/ Reconnected Group in the hub stack. This is an option to isolate or reconnect the Hub Port Configuration Clicking Fault→Group/Port Control→[Port ID] will show the current configuration information of the port. The information is described as follows: ♦ Port Type The type is UTP, BNC, or AUI. ♦ Link Status Indicates link status: link up or link down. ♦ Auto Partition Status not.
♦ Link Test Function State Indicates the whether the port link-test is enabled or disabled. If enabled, the port will check for link pulses, and will only transmit if there is a good link to another station. ♦ Administration State disabled. ♦ Port Speed State or 100Mbps. ♦ Generate Trap When Link State Change Indicates whether or not the port will send a trap if it’s link status changes. ♦ Generate Trap When Speed State Change will send a trap if it’s speed changes.
Dual-Speed Stackable Hub Web-based Management User’s Guide Performance Hub performance is measured with packet statistics and it’s utilization in the network. Statistics The Hub allows you to collect network statistics of individual ports, 10Mbps segments or 100Mbps segments, and any Hub in the stack. Statistics collected by the Hub are described as follows: ♦ StatsPkts (Pkts) Counts valid frames. ♦ BroadcastPkts (Pkts) the network.
♦ CRC AlignErrors (Pkts) byte (octet) boundary. ♦ UndersizePkts (Pkts) Counts packets received that were less than 64 octets long (excluding framing bits, but including FCS octets) and were otherwise well formed. ♦ OversizePkts (Pkts) Counts packets received that were longer than 1518 octets (excluding framing bits, but including FCS octets) and were otherwise well formed.
Dual-Speed Stackable Hub Web-based Management User’s Guide Utilization is calculated and plotted every 10 seconds. At any time, at most, a one hour utilization history can be shown by the graph. User List The User List display, displays the Ethernet (MAC) addresses of packets recently received by the hub stack. This information is displayed per port. The information is described as follows: ♦ 14 Source Address the hub.
♦ Time Shows the amount of time since the last packet was transmitted on the port. Intrusion The Hub’s intrusion security feature can be used to dedicate a port to a given piece of hardware. If a different device transmits to the port, the hub can be set to either partition the port, send a trap notification to the network manager, or both. The device identification is by Ethernet address. The information is described as follows: ♦ Hub ID Select a Hub from the hub stack.
Dual-Speed Stackable Hub Web-based Management User’s Guide ♦ Action The action to be taken in event of intrusion on the port: send trap, partition, send trap & partition, or no action. ♦ Auto Learn Can set auto-learning to enable or disable. ♦ Delete Click this to delete and disable a port/ intrusion entry. Back-Up Port A Back-Up Port is a link pair consisting of a master port and a back-up port. The back-up port is immediately enabled should the master port fail.
