It allows a maximum of four ports to be aggregated at the sa me time and up to 4 gro ups. If the group is defined as a LACP st atic link aggr egationing group, then any ex tra ports selected are placed in a standby mode for redundancy if one of the othe r ports fa ils.
special consideration. The Switch allows you to further tailor ho w priority tagged data p ackets are handled on your net work. Using queues to manage priorit y tagged data allows you to specify its relative priority to suit the needs of your net work.
DEF AUL T_ VLAN port member list. The DEF AUL T _VLAN has a VID = 1. Port-based VLAN Port-based VLAN limit traffic that flows into and out of switch ports. Thus, all devices con nected 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.
priority are used by 802.1p. The VID is the VLAN ident ifier and is us ed by the 802.1Q standard. Becaus e the VID is 12 bits long, 4094 unique VLAN can be identified. The tag is inserted into the packet header making the ent ire packet longer by 4 octets.
T ag-a ware switches must keep a table to relate PVID wi thin the switch to VID on the network. The switch will compare the VID of a p acket to be transmitted to the VID of the port that is to transmit the packet. If the two VID are different the switch will drop the packet.
3. The Port-ba se VLAN Confirutation table then pops up, enter the VLAN group ID, VLAN name and select the member ports for the VLAN. 4. Click the “OK” button to add the VLAN. 5. Select the ports in the Port List field and click on the Add button to ad d the member ports to the VLAN.
802.1Q VLAN Configuration There are up to 256 configur able VLAN groups. By default when 802.1Q is enabled, al l ports on the switch belon g to default VLAN (VID 1). The default VLAN cannot be deleted. Underst and nomenclature of the Switch T agging and Unt agging Every port on an 802.

4.7.5 MAC Address Aging T ime The Aging T ime affects the learning process of the Switch. Dynamic forwarding table entries, which are made up of the source and destination MAC addr e sses and their associated port numbers, are de leted from the table if they are not accessed within the aging time.
4.7.6 802.1X Port-Based Network Access Control 4.7.6.1 Theory Understa nding IEEE 802.1X Po rt-Based Authentication The IEEE 802.1X standard defines a client-server-b ased acce ss control and authenticatio n protocol that restricts unauthorized clients from connecting to a LAN through publicly accessible ports.
z Authentication server —per forms the actual authentication of the client. The authentication server validates the identity of the client and notifies the s witch whether or not the client is aut horized to access the LAN and switch services. Because th e switch ac ts as the proxy , the authentica tion service is transparent to the client.
dropped. If the client does not receive an EA P-requ est/identity frame after three attempts to st art authentication, the client transmits frames as if the port is in the autho rized state. A port in the authorized state effectively means that the client has been successfully authenticated.
If a client that does not support 802.1X is connected to an unauthorized 802.1X port, the switch requests the client's identity. In this situation, the client does not respond to the r equest, the port remains in the unauthoriz ed state, and the client is not granted access to the net work.
4.7.6.2 802.1X Configuration This switch has two 802.1X Mode: Radius Server & Local A uthenticate , choose one you ne ed ● Local Authenticate — In this situation, do not need Rad ius server in the net work, all authentication completed by 802.
EAPOL frames to be sent and received through the port. It’s a default st atus 。 Force authorized: disables 802.1 X authentication and caus es the port to transition to the authorized state without any authentic ation exchange re quired. The por t transmits and receives normal traffic without 802.
● Radius Server — In this situation, need a Radius server in the network, the normal topologies as bel ow 1. Select the “ Radius Serv er ” mode.
• RADIUS Server IP Address The IP address of the RADIUS server being add ed. • Authentication Port(1-65535) The UDP port used by this server. The valid range is 0 - 65535. The default UDP Port No. is 1812 • Account Port(1-65535) The UDP port used by accounting server.
4. Configure ports attribute of 802.1X, the same as “802.1X Port S tatus Configuration”. NOTE: Set the Ports Authenticate S tatus to “Force Author ized” if the port i s c onnected t o the RADIUS server or the port is a uplink port that is conn ected to another switch.

4.8 QoS 4.8.1 Underst and QOS Quality of Service (QoS) is an advanced traffic prioritiza tion feature that a llows you to establish control ov er network traffic. QoS enables you to assign various grades of network service to different types of traffic, such as multi-media, video, protocol-specific, ti me critical, and file-backup traffic.
1. Define a service level to determine the pr iority that will be applied to traffic. 2. Apply a classifier to determine how the incoming traffi c will be classified and thus treated by the Switch. 3. Create a QoS profile which associates a service level and a classifier.
2. VLAN-COS Mapping QoS settings allow customization of VLAN ID to T raffic classifiers 1. Fill the VID (1-2094) field in the VL AN-CoS Mapping T able.
3. 802.1p-CoS Mapping QoS settings allow customization of packet priority in order to facilitate delive ry of data traf fic that might be a ffected by latency problems. The IEEE 802.1p Prio rit y specification uses 8 priority levels to classify data packets.
4. Port-COS Mapping QoS settings allow customization of VLAN ID to T raffic classifiers 1. Fill the Port List (e.g. 1-3,7) field in the port-based QoS Configuration T able. 2. Fill the mapping number in the CoS (0-7) field. 3. Click on the “OK” button to save.
6. Queue Management There are two rules for the Priorit y Queue: Weighted Round Robin ( WRR ) and Always Hight . T o configure Q ueue Rule, select the Queue Policy drop down menu in the Queue Rule Configuration table. And Click on the “OK” button to save.
4.9 Multicast 4.9.1 IGMP Snooping Theory Computers and network devices that want to receive mu lticast transmissi ons need to inform nearby routers that they will become members of a multicast group. The In ternet Group Management Protocol (IGMP) is used to communicate this information.
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 versio n 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.
4.9.2 St atic Routing Port This function is to configure ports to be the member of IGMP Group s in VLANs. T o do this, fill the Port List field and the VID field for the static routing and click on the “Add ” button to save. 4.10 Port Analysis 4.10.
4.10.2 Port Mirror Port Mirroring is a method of monitoring network traffic that forwards a copy of each incoming and/or outgoin g packet from one port of a network switch to another port where the p acket can be studie d. It enables the manager to keep close track of switch performance and alter it if necessar y .
4.1 1 Storm Control This function is to control the Braodcast S torm, Mu lticast S torm and Flooded Storm p acket on each port . T o configure th e S torm Control, click on the Storm Control menu button. The web main page then shows the S trom Restricting function table.
