Ethernet Automatic Protection Switching (EAPS) now supports configurable flush methods to control which MAC addresses are cleared when a ring port fails. Select between port-based flushing (default) or VLAN-and-port-based flushing to optimize convergence timing and MAC relearning in multi-VLAN ring environments.
Issue: When an EAPS ring port fails, stale MAC address entries learned on that port must be cleared to force proper relearning on the alternate path. Previously, EAPS used a fixed flushing strategy that was suboptimal for multi-VLAN deployments, resulting in unnecessary convergence delays and delayed MAC relearning across VLANs not affected by the port failure.
Resolution: Version 34.1.1 introduces the configure eaps flush-method command with two configurable modes: port-based (flush only MAC addresses learned on the failed port) and vlan-and-port-based (flush only MAC addresses learned on the failed port within affected VLANs). This allows operators to reduce the learning scope during failover and improve convergence time in multi-VLAN ring topologies.

configure eaps flush-method [port-based | vlan-and-port-based]
Example: Enable VLAN-and-Port-Based Flushing

This configuration optimizes convergence for multi-VLAN ring topologies by limiting MAC address clearing to only the failed port and affected VLANs.
