Description

Child interfaces should be configured with the same speed to participate in a LAG/AE bundle; child interfaces with different speed settings do not appear under the "show lacp interfaces" command.

Note: When the AE bundle is not configured with "link-speed mixed" knob

Symptoms

The customer was trying to configure the interfaces and add them to the LAG bundle. The customer configured the speed settings on the interfaces, but the change was not committed to the interfaces.

We were able to see different speeds on the member links in the "show interfaces extensive" output.

Solution

The customer had to follow the steps below:

1) Delete the LAG/AE bundle

2) Disable the member-link interfaces

3) Re-enable the interfaces and configure the same speeds on the member links

4) Added it back to the LAG/AE bundle and enabled the LAG/AE.


All member links were added successfully to the LAG/AE.
