GRES support for 802.1X protocol—You can ensure uninterrupted traffic flow during a Routing Engine failure using Graceful Routing Engine Switchover (GRES) support for the 802.1X protocol. The feature maintains client authentication states, preventing traffic loss and MAC learning disruptions. Use the CLI command
