show ports rate-limit flood

show ports { port_list | port_group | tag tag} rate-limit flood {out-actions | out-of-profile {disabled-ports}} {no-refresh | refresh}

Description

Displays rate-limit discard statistics.

Syntax Description

port_list Specifies one or more ports or slots and ports.
port_group Port group name.
tag Display ports in VMAN/VLANs with this IEEE 802.1Q or 802.1ad tag
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.

Default

N/A.

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.

Example

The following command displays information for port 1:1 without a screen refresh on a BlackDiamond 8800 switch:

show port 1:1 rate-limit flood no-refresh

Following is sample output from this command:
