tag Tag ID between 1 and 4095.
rate-limit Displays rate-limit discard statistics.
flood Flood traffic.
out-actions Display out-of-profile actions.
out-of-profile Display rate-limit out-of-profile status.
disabled-ports Display ports that have been disabled due to out-of-profile status.
no-refresh Specifies a static snapshot of data.
refresh Specifies a continous refresh of output.

Usage Guidelines

This command displays the per port ingress rate-limit flood traffic counter as well as information about received packets that have not been discarded due to rate-limiting.

It is used to show the results of the configure ports port_list rate-limit flood [broadcast | multicast | unknown-destmac] [no-limit | pps] command.

Note

Note

As part of the system health check, the system polls the Rate-limit Flood Counters every 5 minutes and looks for non-zero counters on a port. A HAL.RateLimit.Info log message is logged when this is first detected on a port to alert the user that something in the network has triggered the rate limiting to occur. The message is not be logged again unless the counters are cleared.
