Displays WRED and Explicit Congestion Notification (ECN) statistics for the specified ports or all ports.
| 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. |
N/A.
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
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.# show ports 2:1-9 wred no-refresh Port WRED Stats Monitor ============================================================== Port Link Green Yellow Red State Pkt Drop Pkt Drop Pkt Drop ============================================================== 2:1 A 0 0 0 2:2 R 0 0 0 2:3 R 0 0 0 2:4 R 0 0 0 2:5 R 0 0 0 2:6 R 0 0 0 2:7 R 0 0 0 2:8 R 0 0 0 2:9 R 0 0 0 ============================================================== Link State: A-Active, R-Ready, NP-Port Not Present L-Loopback
