Ingress Port List/Egress Port List field can be filled in distinct number or a port range. For example, you can fill with “1, 3”...
LAN on which the packet is transmitted will receive the BPDU. BPDUs are not directly forwarded by the switch, but the receiving switch uses the information in the frame to calculate a BPDU, and, if the topology changes, initiates a BPDU transmission.
Page 32
A designated switch is selected. This is the switch closest to the root switch through which packets 。 will be forwarded to the root. A port for each switch is selected. This is the port providing the best path from the switch to the root 。 switch.
Page 33
2. STP Parameters STP Operation Levels The Switch allows for two levels of operation: the switch level and the port level. The switch level forms a spanning tree consisting of links between one or more switches. The port level constructs a spanning tree consisting of groups of one or more ports.
Page 34
Bridge Priority User-Changeable STA Parameters The Switch’s factory default setting should cover the majority of installations. However, it is advisable to keep the default settings as set at the factory; unless, it is absolutely necessary. The user changeable the switch’s MAC address.
Page 35
BPDU packets sent by the Root Bridge to tell all other Switches that it is indeed the Root Bridge. If you set a Hello Time for your Switch, and it is not the Root Bridge, the set Hello Time will be used if and when your Switch becomes the Root Bridge.
Page 36
LAN 2 The switch with the lowest Bridge ID (switch C) was elected the root bridge, and the ports were selected to give a high port cost between switches B and C. The two (optional) Gigabit ports (default port cost = 4) on switch A are connected to one (optional) Gigabit port on both switch B and C.
B and C is deliberately chosen as a 100 Mbps Fast Ethernet link (default port cost = 19). Gigabit ports could be used, but the port cost should be increased from the default to ensure that the link between switch B and switch C is the blocked link.
128.The lower number has the highest priority. Path Cost: Specifies the path cost of the port. The switch uses this parameter to help determine which port will become a forwarding port. Lower numbers will be used as forwarding ports first. The range is from 0 to 65535.
It allows a maximum of eight ports to be aggregated at the same time. The Switch support Gigabit Ethernet ports (up to 12 groups). If the group is defined as a LACP static link aggregationing group, then any extra ports selected are placed in a standby mode for redundancy if one of the other ports fails. If the group is defined as a local static link aggregationing group, then the number of ports must be the same as the group member ports.

Queue 0 and thus given the lowest priority for delivery. A weighted round robin system is employed on the Switch to determine the rate at which the queues are emptied of packets. The ratio used for clearing the queues is 4:1. This means that the highest priority queue, Queue 1, will clear 4 packets for every 1 packet cleared from Queue 0.

DEFAULT_ VLAN port member list. The DEFAULT_VLAN has a VID = 1. Port-based VLAN Port-based VLAN limit traffic that flows into and out of switch ports. Thus, all devices connected to a port are members of the VLAN(s) the port belongs to, whether there is a single computer directly connected to a switch, or an entire department.
Page 42
Every physical port on a switch has a PVID. 802.1Q ports are also assigned a PVID, for use within the switch. If no VLAN are defined on the switch, all ports are then assigned to a default VLAN with a PVID equal to 1.
VID for tagged packets, tag-aware and tag-unaware network devices can coexist on the same network. A switch port can have only one PVID, but can have as many VID as the switch has memory in its VLAN table to store them.
Page 44
2. The main page then change to Port-base VLAN table, click on the “Add/Modify” button to create a new VLAN group. 3. The Port-base VLAN Confirutation table then pops up, enter the VLAN group ID, VLAN name and select the member ports for the VLAN. 4.
Page 45
802.1Q VLAN information. (Remember that the PVID is only used internally within the Switch). Untagging is used to send packets from an 802.1Q-compliant network device to a non-compliant network device.
Page 46
Switch allows each port to set one PVID, the range is 1~255, default PVID is 1. The PVID must be the same as the VLAN ID that the port was defined as belonging to in the VLAN group, or the untagged traffic will be dropped.
Page 47
3. Choose the Link Type in the drop drop down menu: Access or Trunk. Note that if the Access type is chosen, it will strip the 802.1Q tag from all packets that out of this port. On the other hand, if the Trunk type is chosen, it will put the VID number, priority and other VLAN information into the header of all packets that out of this port.
4.7.2 MAC Address Bind This function is based upon for the switch security. When you add one MAC Address is bind with one port. It remains in the switch's address table, regardless of whether the device is physically connected to the...
If the Network station is connected with one port want to control the switch, the station’s MAC Address must be the same as one MAC Address To bind the MAC Address, click on the Security/MAC Address Binding menu button, the main web page then shows the MAC Address Bind function table.
Address in the Current Filtering MAC Table. 4.7.4 MAC Address Learning The switch is able to disable MAC Address learning function on ports. 1. Fill the Port List field in the MAC Address Learning table and select Enable/Disable in the MAC Address Learning field.
If the Aging Time is too short however, many entries may be aged out too soon. This will result in a high percentage of received packets whose source addresses cannot be found in the forwarding table, in which case the switch will broadcast the packet to all ports, negating many of the benefits of having a switch.
Classifier-classifies the traffic on the network. Traffic classifications are determined by protocol, application, source, destination, and so on. You can create and modify classifications. The Switch then groups classified traffic in order to schedule them with the appropriate service level.
The Switch supports four kinds of Traffic classifiers: 802.1P/ Port/MAC/VLANs and four queues. COS: Priority classifiers of the Switch forward packet. COS range is from 0 to 7. Seven is the NOTE: high class. Zero is the less class. The user may configure the mapping between COS and Traffic classifiers.

2. VLAN-COS Mapping QoS settings allow customization of VLAN ID to Traffic classifiers Fill the VID (1-2094) field in the VLAN-CoS Mapping Table. Fill the mapping number in the CoS (0-7) field. Click on the “OK” button to save. To remove the VLAN-CoS mapping item, simply click on the “Delete” button in the Show VLAN-CoS Mapping table.
Page 55
3. 802.1p-CoS Mapping QoS settings allow customization of packet priority in order to facilitate delivery of data traffic that might be affected by latency problems. The IEEE 802.1p Priority specification uses 8 priority levels to classify data packets. In 802.1p compliant devices, a tag inserted into the packet header is used to identify the priority level of data packets.
Page 56
4. Port-COS Mapping QoS settings allow customization of VLAN ID to Traffic classifiers Fill the Port List (e.g. 1-3,7) field in the port-based QoS Configuration Table. Fill the mapping number in the CoS (0-7) field. Click on the “OK” button to save. 5.

6. Queue Management There are two rules for the Priority Queue: Weighted Round Robin (WRR) and Always Hight. To configure Queue Rule, select the Queue Policy drop down menu in the Queue Rule Configuration table. And Click on the “OK” button to save. If the WRR was chosen as the Queue Policy, the page would show in the main page.
4.9 Multicast 4.9.1 IGMP Snooping Theory Computers and network devices that want to receive multicast transmissions need to inform nearby routers that they will become members of a multicast group. The Internet Group Management Protocol (IGMP) is used to communicate this information. IGMP is also used to periodically check the multicast group for members that are no longer active.
Page 59
A host sends an IGMP “report” to join a group A host will never send a report when it wants to leave a group (for version 1). A host will send a “leave” report when it wants to leave a group (for version 2). Multicast routers send IGMP queries (to the all-hosts group address: 224.0.0.1) periodically to see whether any group members exist on their sub networks.
4.9.2 Static Routing Port This function is to configure ports to be the member of IGMP Groups in VLANs. To do this, fill the Port List field and the VID field for the static routing and click on the “Add” button to save.
Port Mirroring is a method of monitoring network traffic that forwards a copy of each incoming and/or outgoing packet from one port of a network switch to another port where the packet can be studied. It enables the manager to keep close track of switch performance and alter it if necessary.
4.11 Storm Control This function is to control the Braodcast Storm, Multicast Storm and Flooded Storm packet on each port. To configure the Storm Control, click on the Storm Control menu button. The web main page then shows the Strom Restricting function table. Fill the Port List field in the Broadcast Storm Restricting table, select the type in the Restricting Type drop down menu and enter the packet size in the Flow field.
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 a while check for loose power connections, power losses or surges at power outlet. IF you still cannot resolve the problem,...
5.2.1 Cabling RJ-45 ports: use unshielded twisted-pair (UTP) or shield 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. Also be sure that the length of any twisted-pair connection does not exceed 100 meters (328 feet).
6.1 Console Port Pin Assignments The DB-9 serial port on the front panel is used to connect to the switch for out-of-band console configuration. The console menu-driven configuration program can be accessed from a terminal or a PC running a terminal emulation program. The pin assignments used to connect to the serial port are provided in the following tables.
"+" and "-" signs represent the polarity of the wires that make up each wire pair. Note: All ports on this switch support automatic MDI/MDI-X operation, you can use straight-through cables for all network connections to PCs or servers, or to other switches or hubs. In straight-through cable, pins 1, 2, 3, and 6, at one end of the cable, are connected straight through to pins 1, 2, 3 and 6 at the other end of the cable.
