Verifying LACP on Stand-Alone Devices

Verifying LACP Statistics

Purpose

Display LACP statistics for aggregated Ethernet interfaces.

Action

From the CLI, enter the show lacp statistics interfaces ae0 command.

Sample Output

user@host> show lacp statistics interfaces ae0

Aggregated interface: ae0
    LACP Statistics:       LACP Rx     LACP Tx   Unknown Rx   Illegal Rx 
      ge-2/0/0                1352        2035            0            0
      ge-2/0/1                1352        2056            0            0
      ge-2/2/0                1352        2045            0            0
      ge-2/2/1                1352        2043            0            0

Meaning

The output shows LACP statistics for each physical interface associated with the aggregated Ethernet interface, such as the following:

The LACP received counter that increments for each normal hello
The number of LACP transmit packet errors logged
The number of unrecognized packet errors logged
The number of invalid packets received

Use the following command to clear the statistics and see only new changes:

user@host# clear lacp statistics interfaces ae0

Verifying LACP Aggregated Ethernet Interfaces

Purpose

Display LACP status information for aggregated Ethernet interfaces.

Action

From the CLI, enter the show lacp interfaces ae0 command.

Sample Output

user@host> show lacp interfaces ae0

Meaning

The output shows aggregated Ethernet interface information, such as the following:

The LACP state—Indicates whether the link in the bundle is an actor (local or near-end of the link) or partner (remote or far-end of the link).
The LACP mode—Indicates whether both ends of the aggregated Ethernet interface are enabled (active or passive)—at least one end of the bundle must be active.
The periodic link aggregation control PDU transmit rate.
The LACP protocol state—When the link is up, it is collecting and distributing packets.
