Authentication and Access Control
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 show dot1x sync-pending-sessions to view unsynced authenticated sessions post-switchover and ensure proper session synchronization. This enhancement allows seamless transitions without client disconnections, ensuring continuous network access and stability.
