Verifying That LACP Is Configured Correctly and Bundle Members Are Exchanging LACP Protocol Packets
Verify that LACP has been set up correctly and that the bundle members are transmitting LACP protocol packets.
Verifying the LACP Setup
Verify that the LACP has been set up correctly.
To verify that LACP has been enabled as active on one end:
user@switch>show lacp interfaces xe-0/0/0
Aggregated interface: ae0 LACP state: Role Exp Def Dist Col Syn Aggr Timeout Activity xe-0/1/0 Actor No Yes No No No Yes Fast Active xe-0/1/0 PartnerNo Yes No No No Yes Fast Passive LACP protocol: Receive State Transmit State Mux State xe-0/1/0 Defaulted Fast periodic Detached
This example shows that LACP has been configured with one side as active and the other as passive. When LACP is enabled, one side must be set as active in order for the bundled link to be up.
Verifying That LACP Packets Are Being Exchanged
Verify that LACP packets are being exchanged between interfaces.
Use the show lacp statistics interfaces interface-name command to display LACP BPDU exchange information.
show lacp statistics interfaces ae0
Aggregated interface: ae0 LACP Statistics: LACP Rx LACP Tx Unknown Rx Illegal Rx xe-0/0/2 1352 2035 0 0 xe-0/0/3 1352 2056 0 0
The output here shows that the link is up and that PDUs are being exchanged.
