L2BSA Operational Commands

The following commands allow to list or clear all L2BSA services from CLI.

L2BSA subscribers can be managed like any other subscriber using the subscriber CLI commands.

The CLI also provides some global intermediate agent function packet statistics about traffic received in the control plane which belong to L2BSA subscribers.

supervisor@leaf1: op> show l2bsa intermediate-agent statistics
PPPoE Discovery Sent        : 0
PPPoE Discovery Updated     : 0
PPPoE Discovery Dropped     : 0

The sent statistics count all intermediate agent traffic forwarded back to L2X while updated only counts those which are also updated or enriched by access line information. Dropped are those packets received but dropped by the L2BSA subscriber state which might be the case if the L2BSA subscriber is still present but in a terminating state.
