5-4-2-2.Advanced 1. Miscellaneous Settings: MAC Address Age-out Time: Type the number of seconds that an inactive MAC address remains in the switch's address table. The valid range is 300 to 765 seconds. Default is 300 seconds. Max bridge transit delay bound control: Limits the packets queuing time in the switch. If enabled, the packets that exceed the time limit in the queue will be dropped. This valid values are 1sec, 2 sec, 4 sec and off. Default is 1 second.
2. Priority Queue Service settings: First Come First Service: The sequence of packets sent is dependent on the order of arrival. The first packets in the queue are transmitted before any other packets. All High before Low: The high priority packets are sent before the low priority packets. Weighted Round Robin: This option enables the user to choose a ratio of the number of high priority packets sent before one low priority packet is sent.
77
3. Protocol Enable Setting: Enable Spanning Tree Protocol: Enables STP. The recommended default is to disable STP. Enable Internet Group Multicast Protocol: Enables IGMP protocol. IGMP Query Mode: Recognizes different queries from clients or servers to decide which Query will be the first priority. The four modes are: Auto Mode: Chooses the switch that has the smallest IP address to be set for the IGMP Query mode. Enable Mode: Enables the switch to be the IGMP Querier.
4. IGMP Theory of Operation The following three topologies detail how IGMP Query works and to be configured within a network: 1. Auto mode needs to be enabled when the router’s IP address is smaller than other switches in the subnet. 2. IGMP needs to be enabled when the router’s IP address is not smaller than other switches in the subnet. This Router supports IGMP protocol, but IGMP has to be enabled, and the Router has to be the Querier.
80
3. The following topology must be set when the IP address of the switch is not the smallest in the subnet. The network will cause a multi-cast storm from the IGMP client report if it is in Auto mode. All switches must be in disable mode when the VOD server is configured for IGMP Querier. Note: It is suggested that the VOD server switch have the smallest IP address. GVRP (GARP VLAN Registration Protocol) GVRP allows automatic VLAN configuration between the switch and nodes.
5-4-3. Console Port Information Console is a standard UART interface to communicate with a serial port. The Windows HyperTerminal program can be used to link the switch with the console port. In order to change any of these parameters, you must be connected to the console port.
5-4-4. Port Controls The menu allows changing of port configurations. State: User can disable or enable ports 1-8, port 9 is always enabled. Auto Negotiation: Ports 1-8 are fixed to disabled mode, and port 9 is enabled. Speed setting: Ports 1-8 are set at a fixed speed of 100Mbps. Port 9 is fixed at 1000Mbps (SFP port). Duplex setting: User can set ports 1-8 to Full Duplex or Half Duplex. Port 9 is fixed at Full Duplex.
on the network. LACP operation requires full-duplex mode. For more detailed information refer to IEEE 802.3ad. If there are two trunk groups A and B, and B group is enabled LACP, then it will act as a redundant link (Backup group for Trunk group A). If trunk group A fails, Group B will be it's backup.
5-4-5-1. Aggregator Setting System Priority: A value used to identify the active LACP. The switch with the lowest value has the highest priority and is selected as the active LACP. To create a trunk across two or more ports: 1. Group ID: Choose the "Group ID" and click "Get". 2. LACP: If enabled, the group supports LACP. If disabled, the group is a local static trunking group between two switches. All ports support LACP dynamic trunking group.
5-4-5-2. Aggregator Information The LACP Aggregator relation information is displayed as shown. 5-4-5-3. State Activity Active (select): The active port automatically sends LACP protocol packets. Passive (not selected): The passive port does not automatically send LACP protocol packets, but responds only if it receives LACP protocol packets from the other device. A link having either two active LACP ports or one active port can perform dynamic LACP trunking.
87
5-4-6. Filter Database 5-4-6-1. IGMP Snooping The switch supports IP multicasting. You can enable IGMP via the web management’s configuration screen. In addition, you can view different multicast groups, VIDs and member ports, and IP multicast addresses that range from 224.0.0.0 through 239.255.255.255. The Internet Group Management Protocol (IGMP) is an internal protocol of the Internet Protocol (IP) suite. IP manages multicast traffic by using switches, routers, and hosts that support IGMP.
5-4-6-2. Static MAC Address When a static MAC address is added, it remains in the switch's address table, regardless of whether or not the device is physically connected to the switch. This saves the switch from having to re-learn a device's MAC address when the device is disconnected or powered-off. To add a static MAC address: 1. Click on Administrator on the main menu. 2. Click on Filter Database. 3. Click Static MAC Addresses.
5-4-6-3. Port Security A port in security mode will be “locked” with address learning blocked. Only the incoming packets with SMAC already existing in the address table can be forwarded normally. The user can disable the port from learning any new MAC addresses, then use the static MAC addresses screen to define a list of MAC addresses that can use the secure port. Enter the settings, and then click Apply to submit the changes on this page.
5-4-6-4. MAC Filtering MAC address filtering allows the switch to drop unwanted traffic. Traffic is filtered based on the destination addresses. Steps to specify a MAC address to filter: 1. In the MAC Address box, enter the MAC address to filter. 2. If tag-based (802.1Q) VLAN are set up on the switch, in the VLAN ID box, type the VID to associate with the MAC address. 3. Click the Add button. 4.
5-4-7. VLAN Configuration A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain. It allows you to isolate network traffic so only members of the VLAN receive traffic from the same VLAN members. Basically, creating a VLAN from a switch is logically equivalent of reconnecting a group of network devices to another Layer 2 switch. However, all the network devices are still plugged into the same switch physically. The MIL-SM808G switch supports port-based and protocol-based VLANs.
5-4-7-1. Basic VLAN Configuration By default, there are no VLANs set for the switch. In order to configure any of the different types of VLANs, VLANs need to be enabled in the switch using Settings/Advanced/Protocol Enable Settings/VLAN Operational Mode. The following are the choices offered: Port Based VLANs This screen shows the current Port Based VLANs configured. To configure new VLANs click the Add button. You can also delete configured VLANs using this screen.
switch on separate VLANs except for the port that has the server connected to it. This port is then shared by all the VLANs. This enables security between ports, but allows all ports access to the server. Create a VLAN and add tagged member ports to it. 1. From the main menu, click Administrator -- VLAN Configuration. 2. Click Add. 3. Type a name for the new VLAN. 4. Type a VID (between 2 to 4094). The default is 1. 5. From the Available ports box, select ports to add to the switch and click Add. 6.
5-4-7-2. Port VID Configure port VID settings: From the main Tag-based (IEEE 802.1Q) VLAN page, click Port VID Settings. Port VID (PVID) Used for setting the Port VLAN ID that will be assigned to untagged traffic on a given port. For example, if port 9's Default PVID is 100, all untagged packets on port 9 will belong to VLAN100. The default setting for all ports is VID1. This feature is useful for accommodating devices that you want to participate in the VLAN but that don't support tagging.
Ingress Filtering Rule 2: Drop Untagged Frame. By default all untagged frames are forwarded.
5-4-8. Spanning Tree The Spanning-Tree Protocol (STP) is a standardized method (IEEE 802.1D) for avoiding loops in switched networks. When STP is enabled it ensures that only one path at a time is active between any two nodes on the network. Spanning-Tree Protocol can be enabled using web management’s switch setting advanced item, and selecting enable Spanning-Tree protocol. By default, spanning tree is disabled on the switch.
Information about the current spanning tree status is displayed in this table. Parameter Description The priority value used to identify the root bridge can be changed. The Priority bridge with the lowest value has the highest priority and is selected as the root. Enter a number 1 through 65535. Max Age value is the number of seconds a bridge waits without receiving Max Age Spanning-Tree Protocol configuration messages before attempting a reconfiguration.
The priority and path cost can be configured for each port. Click the Apply button to modify the configuration. Parameter Port Priority Description A change to the Port Priority affects which port will be the root port. The lowest number has the highest priority. The range is 0-255 and the default setting for all ports is 128. Path Cost specifies the path cost of the port that the switch uses to Path Cost determine which ports are the forwarding ports. The lowest number becomes the forwarding port.
5-4-9. Port Mirroring The Port Mirroring feature is disabled by default. Selecting enable from the pull down menu will cause the selected traffic from the selected monitor ports to be mirrored to the selected analysis port. Press the Apply button to submit the changes. Port Mirroring State: Enables or disables the port mirroring function. Analysis Port: The ports you want to mirror. All source port traffic will be copied to a mirror port. You can select a maximum of 9 source ports in the switch.
5-4-10. SNMP SNMP is a protocol that governs the transfer of information between management and agent. The switch supports SNMP V1. Any Network Management station running the Simple Network Management Protocol (SNMP) can manage the switch provided that the Management Information Base (MIB) is installed. Use this menu to define management stations as trap managers and to enter SNMP community strings. Users can also define community strings for a name, location, and contact person for the switch. 1.
Read only: Enables requests accompanied by this string to display MIBobject information. Read write: Enables requests accompanied by this string to display MIBobject information and to set MIB objects. 3. Trap Manager A trap manager is a management station that receives traps. Traps are the system alerts generated by the switch. If no trap manager is defined, no traps are issued. Create a trap manager by entering the IP address of the station and a community string.
5-4-11.Security Manager The user can change the user name and password to keep the switch secure. The default user name and password are below.
5-4-12. TFTP Update Firmware The following menu options provide some system control functions to allow a user to update firmware and remotely boot the switch system: • Executing TFTP software • Copy firmware update version image.bin to TFTP software directory. • In web management select Administrator—TFTP update firmware. • Download new image.bin file. In web management, press . 5-4-13. Configuration Backup 5-4-13-1. TFTP Restore Configuration Use this screen to set TFTP server address.
5-4-13-2. TFTP Backup Configuration Use this screen to set the TFTP server IP address. You can save current EEPROM value from here, then go to the TFTP Restore Configuration screen to restore the EEPROM value.
5-4-14. Reset System Reset Switch to default configuration. 5-4-15. Reboot Select Reboot to restart the system with the current saved configuration.

7. Troubleshooting This section is intended to help you solve some common problems encountered while using the MIL-SM808G switch series. Incorrect connections Faulty or loose cables Look for loose or obviously faulty connections. If they appear to be OK, make sure the connections are snug. If that does not correct the problem, try different cables. Non-standard cables Non-standard and miswired cables may cause numerous network collisions and other network problems.
Diagnostic LED Indicators The switch can be easily monitored through panel indicators to assist in identifying problems. If the power indicator does turn on when the power cord is plugged in, you may have a problem with power outlet or power cord. However, if the switch powers off after running for awhile, check for loose power connections, power losses or surges at power outlet. If you still cannot resolve the problem, contact your local dealer for assistance.
