Description

Currently there is an AE interface configured with a manual link speed line. The child member interfaces used certain speed and will be replaced with new child ports that run a different speed. When trying to save the changes a commit error arises.
 
 

Symptoms

Customer scenario:
 
  • The link speed (AE) was originally set to 50G
  • The member interfaces were et-/0/0/7 et-1/0/7 originally set to 25G each.
  • The members  links were changed to 0/0/33 and 1/0/33 and these interfaces are currently running default 10G.

When trying to commit the error messages are display:

root@jtac-EX4400-48MP-r001# commit
error: Speed mismatch between ae0 and xe-0/0/33
error: Speed mismatch between ae0 and xe-1/0/33
error: Interface ae0 with child links of mixed speed but link-speed mixed is not configured
error: configuration check-out failed

Solution

To clear the error please follow the below steps:

- Remove the old interfaces from the AE logical port (AE0 in this example):
 
#delete interfaces et-0/0/7 ether-option 802.3ad ae0
#delete interfaces et-0/0/7 ether-option 802.3ad ae0

- Add the new interfaces to the AE port:
 
#set interfaces xe-0/0/33 ether-option 802.3ad ae0
#set interfaces xe-1/0/33 ether-option 802.3ad ae0

- Remove the speed configuration from the AE port:
 
#delete interface ae0 aggregated-ether-options link speed

- Save the changes:
 
root@jtac-EX4400-48MP-r001# commit
