Description

This article describes the issue of the AE interface configuration not showing up after being committed.

Symptoms

The AE interface configuration gets committed, but it does not show up and it is not displayed even in the output of show interfaces terse : 

[edit interfaces]
lab@lab-MX80# commit 
commit complete

[edit interfaces]
lab@lab-MX80# show 
ge-1/0/0 {
    gigether-options {
        802.3ad ae0;
    }
}
ae0 {
    unit 0 {
        family inet {
            address 2.2.2.2/30;
        }
    }
}

[edit interfaces]
lab@lab-MX80# run show interfaces terse | match ae0 
ge-1/0/0.0              up    up   aenet    --> ae0.0

[edit interfaces]
lab@lab-MX80#

Solution

When creating an aggregate interface on Ethernet, you also have to enable the following command; the AE interface will not be created:

set chassis aggregated-devices ethernet device-count 1
The device count must equal the highest value of the AE interface +1. So, in this example, device count = 1. If ae0 and ae1 are required, then device count = 2; so on and so forth: 
[edit interfaces]
lab@lab-MX80# top edit chassis 

[edit chassis]
lab@lab-MX80# set aggregated-devices ethernet device-count 1 

[edit chassis]
lab@lab-MX80# commit 
commit complete

[edit chassis]
lab@lab-MX80# run show interfaces terse | match ae0             
ge-1/0/0.0              up    up   aenet    --> ae0.0
ae0                     up    up
ae0.0                   up    up   inet     2.2.2.2/30
