show ports wred

show ports port_list wred ecn {no-refresh | refresh}

Description

Displays WRED and Explicit Congestion Notification (ECN) statistics for the specified ports or all ports.

Syntax Description

port_list Specifies a list of slots and ports to display. Specify ports in the following formats: 3-5, 2:5, 2:6-2:8.
no-refresh Specifies a static snapshot of data instead of the default dynamic display.
refresh Continuous refresh of output.
ecn Displays ECN statistics.

Default

N/A.

Usage Guidelines

If no port or port list is specified, this command displays the WRED statistics for all ports. If WRED is not configured on a port, the statistics for that port display as 0.

The drop counters in the display represent packets that were dropped based on the WRED congestion avoidance algorithm. The Green Pkt Drop column counts in-profile TCP and non-TCP packets that have been dropped. The Red Pkt Drop column counts out-of-profile TCP and non-TCP packets that have been dropped.

Note

Note

The values in the Yellow Pkt Drop column are always 0 in this release because the yellow traffic color is not supported at this time.

Example

The following example displays the WRED statistics for port list 2:1-9:
# show ports 2:1-9 wred no-refresh
