Excluding a port from bottleneck detection

13

For trunking, if you exclude a slave port from bottleneck detection, the exclusion has no effect as
long as the port is a trunk slave. The exclusion takes effect only if the port becomes a trunk master
or leaves the trunk.

Use the following procedure to exclude a port from bottleneck detection:

1. Connect to the switch to which the target port belongs and log in using an account with admin

permissions.

2. Enter the bottleneckmon --exclude command to exclude the port from bottleneck detection.

To later include the port, enter the bottleneckmon --include command.

Example showing how to exclude a single port from bottleneck detection

This example excludes port 7 only from bottleneck detection. See

“Disabling bottleneck detection

on a switch”

on page 392 for more information on this command.

NOTE

Excluding the master port excludes the entire trunk, even if individual slave ports are not excluded.

Example showing how to re-include bottleneck detection for a port

This restores bottleneck detection for port 7. Notice that the “Excluded ports” section is not
displayed as there are no excluded ports.

switch:admin> bottleneckmon --include 7
