IP Address The IP Settings can be changed by filling in new values and clicking on the apply button. The switch must be reset for the new IP address to take effect. Default IP address is 192.168.1.77.
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 300~765 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. The valid values are 1 sec, 2 sec, 4 sec and off (no limit). 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.
3. Protocol Enable Setting: Enable Spanning Tree Protocol: Enables STP. The recommended default is enabled. 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 three modes are: 1. Auto Mode: Chooses the switch that has the smallest IP address to be set for the IGMP Query mode. 2. Enable Mode: Enables the switch to be the IGMP Queryer. 3.
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 Queryer.
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 Queryer. Note: It is suggested that the VOD server switch have the smallest IP address. All of the switches must be in disable mode when the VOD server is configured for IGMP Queryer.
5-4-3. Console Port Information 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 this port. If disabled, there is no network communication through this port. Auto Negotiation: User can set port duplex and port speed to use auto negotiation. Speed setting: User can set 100Mbps or 10Mbps speed (Port1~Port8) Duplex setting: User can set port to use full-duplex or half-duplex. Flow control setting: User can set flow control function to be enabled or disabled. 5-4-5.
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. 1. Group ID: To create a trunk across two or more ports, 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 (no select): 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.
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 difference 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 Submit to apply the changes on this page.
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 to reconnecting a group of network devices to another Layer 2 switch. However, all the network devices are still plugged into the same switch physically.
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.
Create a VLAN and add tagged member ports. 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 2-4094). The default is 1. 5. From the Available ports box, select ports to add to the switch and click Add. 6. Click Apply.
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 VLAN 100. The default setting for all ports is VID 1. This feature is useful for accommodating devices that you want to participate in the VLAN but that don't support tagging.
5-4-8. Set 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. The priority and path cost can be configured for each port. Click the Apply button to modify the configuration. Description Port Priority 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. If you change the value, you must reboot the switch.
5-4-9. Port Mirroring The Port Mirroring feature can monitor traffic in switched networks. Traffic transmitted or received on monitored ports (source ports) will be duplicated to a destination port or mirror port. Analysis State: Enables or disables the port mirroring function. Mirror Ports: The ports you want to mirror. All source port traffic will be copied to a mirror port. You can select a maximum of 8 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.
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.

7. Troubleshooting This section is intended to help you solve some common problems encountered while using the MIL-SM801P, MIL-SMS801G, and MILSM800P 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.
Cabling RJ-45 ports: Use unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable for RJ-45 connections: 100Ω Category 3, 4 or 5 cable for 10Mbps connections or 100Ω Category 5 cable for 100Mbps connections. Be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet). 100BASE-FX fiber port: Multi-mode fiber connector types must use 50/125 or 62.5/125 µm multi-mode fiber cable. Two devices may be connected over a 2 kilometer distance.
