제품 코드

TL-SL5428E

Operation Mode:

Select the mode how the switch processes the detected loops.



Alert: When a loop is detected, display an alert.



Port based: When a loop is detected, display an alert and
block the port.

Recovery Mode:

Select the mode how the blocked port recovers to normal status.



Auto: Block status can be automatically removed after
recovery time.



Manual: Block status only can be removed manually.

Loop Status:

Displays the port status whether a loopback is detected.

Block Status:

Displays the port status about block or unblock.

LAG:

Displays the LAG number the port belongs to.

Manual Recover:

Manually remove the block status of selected ports.

Note:

1. Recovery Mode is not selectable when Alert is chosen in Operation Mode.

2. Loopback Detection must coordinate with storm control.

5.2 LAG

LAG (Link Aggregation Group) is to combine a number of ports together to make a single

high-bandwidth data path, so as to implement the traffic load sharing among the member ports in

the group and to enhance the connection reliability.

For the member ports in an aggregation group, their basic configuration must be the same. The

basic configuration includes STP, QoS, GVRP, VLAN, port attributes, MAC Address Learning

mode and other associated settings. The further explains are as following:



If the ports, which are enabled for the GVRP, 802.1Q VLAN, Voice VLAN, STP, QoS, Port

Isolation, DHCP Snooping and Port Configuration (Speed, Flow Control), are in a LAG,

their configurations should be the same.



The ports, which are enabled for the Port Security, Port Mirror, MAC Address Filtering,

Static MAC Address Binding, 802.1X Authentication, IP Source Guard, and half-duplex

can not be added to the LAG.



It’s not suggested to add the ports with ARP Inspection and DoS Defend enabled to the

LAG.

If the LAG is needed, you are suggested to configure the LAG function here before configuring the

other functions for the member ports.

Tips:

1. Calculate the bandwidth for a LAG: If a LAG consists of the four ports in the speed of

1000Mbps Full Duplex, the whole bandwidth of the LAG is up to 8000Mbps (2000Mbps * 4)
because the bandwidth of each member port is 2000Mbps counting the up-linked speed of
1000Mbps and the down-linked speed of 1000Mbps.
