 Display local information of channel group

show lacp internal [channel-group-number]

Use show lacp interval command to display the information of group members, if the there is

no keywords, all groups are displayed.

For example: Display the member information of channel group 2.

QTECH#show lacp internal 2

 Display information of neighbour interface of channel group

show lacp neighbor [channel-group-number]

Use show lacp neighbor command to display the information of the neighbour port in the

group. If there is no keyword, the neighbor ports of all the groups are displayed.

For example: Display the information of the neighbour port of the group 2

QTECH#show lacp neighbor 2

2.5 Interface CAR configuration

2.5.1 Brief introduction of interface CAR

Interface CAR is used to restrict the speed rate impacted CPU of single interface. CPU can

make speed rate statistics of each interface. If the speed rate is larger than the configured

threshold (it is defaulted to be 300 packet/second), disable this interface and send trap of

interface being abnormal. After a certain time (it is defaulted to be 480 seconds), re-enable the

interface. If this interface will not be re-disabled by interface CAR in 2 seconds, the storm of

impacting CPU by interface is over, and the interface recovers, and sends the trap of interface

being normal. Caution: If the re-enabled interface is disable again by impacting CPU packet in

2 seconds, no trap of interface being abnormal is sent.

2.5.2 Port CAR configuration command list

Port CAR configuration command includes:

 Enable/disable interface CAR globally

 Enable/disable interface CAR on a port

 Configure interface CAR re-enable time

 Configure interface CAR

 Display interface CAR status

2.5.3 Enable/disable interface globally

Configure it in global configuration mode

 Enable global interface

port-car

 Disable global interface

no port-car

By default, port-car globally enables

For example:

! Enable port-car globally

QTECH(config)#port-car

2.5.4 Enable/disable interface CAR on a port

Please configure it in interface configuration mode:
