[RESOLVED] Flood-limit

Topic

Hi,
I have configured flood-limit on port 1/1/1 244 pps
ALU-SWITCH# show interfaces port 1/1/1 flood-rate
Chas/
Slot/ Bcast Bcast Bcast Ucast Ucast Ucast Mcast Mcast Mcast
Port Value Type Status Value Type Status Value Type Status
——–+———+—-+——-+———+—-+——-+———+—-+——–
1/1/1 244 pps enable 244 pps enable 244 pps enable

how to check the status of port if its reaches the required limit? the action was shutdown if the threshold was reached.

this is the status of port 1/1/1

Hi

It seems you have configured flood-limit for unknow-unicast, broadcast, multicast with 244 packets per second.

If you receive more than 244 packets on the switch port (which should be either broadcast traffic with All FF's MAC address or multicast traffic with Multicast MAC address or the traffic with unknown MAC addresses) in a second on the port 1/1/1 then only the switch will shutdown the port.

Do you enable auto recovery for the port such as - if traffic got reduced than the configured limit the port can brought back to the operational by the switch itself?

You can check the statistics of the port "show interfaces port 1/1/1 statistics",please verify command based on the model and validate your test.
