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.

EVPN MPLS E-Tree Scenario 2 Support
OcNOS introduces support for EVPN E-Tree Scenario 2 (SC-2), enabling Root and Leaf sites to co-exist on the same PE within a single EVI. The feature enforces strict Leaf-to-Leaf isolation for both unicast and BUM traffic through ingress and egress filtering, using new E-Tree Extended Community attributes in RT-1 and RT-2 routes. Scenario 2 supports both single-homed and multi-homed topologies and applies only to Qumran2 (Q2) series platforms, ensuring efficient hardware-based Leaf Label enforcement for secure and flexible E-Tree deployments.

Introduction of Ethernet Data Plane Loopback (EDPL)
Introduced the Ethernet Data Plane Loopback (EDPL) feature to enable RFC 2544-compliant performance testing on Ethernet interfaces. EDPL allows the device to operate as a reflector by looping back test traffic received from an external traffic generator, swapping packet headers such as MAC addresses, IP addresses, and UDP/TCP ports. The feature supports Layer 2, IPv4, and IPv6 loopback across physical ports, sub-interfaces, and logical interfaces (SVI, IRB, BVI) in both upstream and downstream directions. It enables operators to validate performance metrics such as throughput, latency, and frame loss without requiring external traffic reflection devices. In this release, only reflector functionality is supported, and the feature is available on Jericho2 and Jericho2c+ (J2C+) series platforms.
For more details, see the Ethernet Data Plane Loopback (EDPL) section of the OcNOS Multi-Protocol Label Switching 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.

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.
