Select: Port: Status: Operation Mode: Recovery Mode: Loop Status: Block Status: LAG: Recover: Select the desired port for Loopback Detection configuration. It is multi-optional. Displays the port number. Enable or disable Loopback Detection function for the port. 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. 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. Displays the port status whether a loopback is detected. Displays the port status about block or unblock. Displays the LAG number the port belongs to. Click the Recover button to manually remove the block status of selected ports. Note: Loopback Detection must coordinate with storm control. 6.2 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, VLAN, port attributes, MAC Address Learning mode and other associated settings. More details are explained below:  If the ports, which are enabled for the 802.1Q VLAN, STP, QoS and Port Configuration (Speed and Flow Control), are in a LAG, their configurations would be the same as the LAG's.  The ports, which are enabled for the half-duplex, Port Security, Port Mirror and MAC Address Filtering, cannot be added 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. 55

6.2 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
,
VLAN
,
port attributes
,
MAC Address Learning mode
and other associated settings. More details are explained below:
If the ports, which are enabled for the
802.1Q VLAN
,
STP
,
QoS
and
Port Configuration
(
Speed and Flow Control
), are in a LAG, their configurations would be the same as the
LAG’s.
The ports, which are enabled for the
half-duplex
,
Port Security
,
Port Mirror
and
MAC
Address Filtering
, cannot be added 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.
