Layer 2 Service Enhancements

Enhanced LACP Force-up Behavior

OcNOS introduces the 90-second activation delay timer for LACP force-up links. A link enters the force-up state after 90 seconds without PDUs on all member links and immediately exits when PDUs are received. The timer restarts when a member link flaps.

For more details, refer to the LACP Aggregator Force-up section in the OcNOS Layer 2 Guide, Release 7.0.0.

Added Clear LLDP Neighbors

Introduced a new CLI command clear lldp neighbors to allow operators to dynamically clear LLDP neighbor information. This enhancement enables users to remove all learned LLDP neighbors at once or selectively clear entries associated with a specific interface, providing operational flexibility for troubleshooting neighbor discovery, validating link changes, and refreshing LLDP state without requiring a system or process restart. The feature is available in both Exec and Privileged Exec modes and helps maintain accurate and up-to-date LLDP topology information.

For more details, refer to the Link Layer Discovery Protocol Commands section of the OcNOS Layer 2 Guide, Release 7.0.0.

Disable MAC Learning on Layer 2 Protocol Packets

Introduced a new CLI l2protocol all learn-disable command to disable MAC address learning from all Layer 2 protocol data units (BPDUs) received on the device. When configured, the device does not learn the source MAC addresses of Layer 2 control protocol packets, including xSTP, LACP, EAP, LLDP, EFM, SyncE, and ELMI, on any interface.

For more details, see the l2protocol all learn-disable topic in the OcNOS System Management Guide, Release 7.0.0.
