logical unit is not allowed on aggregated links

During deployment I found an above error when i commit my config

Before going to create aggregation and deploying LACP on juniper switches you have to remove interfaces from unit 0.

Run below mentioned commands.

• root#delete interfaces ge-0/0/0 unit 0
• root#delete interfaces ge-0/0/1 unit 0

or remove all interfaces which you plan to be the part of aggregation group.

Then run the following commands.


root# edit chassis

{master:0}[edit chassis]
root# set aggregated-devices ethernet device-count 4

{master:0}[edit chassis]
root# commit
configuration check succeedscommit complete

{master:0}[edit chassis]
root# top edit interfaces

{master:0}[edit interfaces]
root# top edit interfaces

{master:0}[edit interfaces]

root# set ae0 unit ?
Possible completions:
<interface-unit-number> Logical unit number
{master:0}[edit interfaces]
root# set ae0 unit 0 family ethernet-switching

{master:0}[edit interfaces]
root# set ae0 aggregated-ether-options lacp active

root# set ge-0/0/1 ether-options 802.3ad ae0

{master:0}[edit interfaces]
root# set ge-0/0/2 ether-options 802.3ad ae0

root> show interfaces terse | match ae0
ge-0/0/1.0 up down aenet --> ae0.0
ge-0/0/2.0 up down aenet --> ae0.0
ae0 up down
ae0.0 up down eth-switch
