(Optional) Configuring the Function of Triggering 802.1X Authentication Through Multicast Packets Immediately After an Interface Goes Up
Context
By default, the device periodically multicasts EAP-Request/Identity packets to clients so that the clients are triggered to send EAPoL-Start packets for 802.1X authentication. If the device interface connecting to a client changes from Down to Up, the client needs to send EAPoL-Start packets again for 802.1X authentication, which takes a long time. You can enable the function of triggering 802.1X authentication through multicast packets immediately after the device interface goes Up, shortening the re-authentication time.
When the access control mode on the device interface is based on the MAC address, the dot1x mc-trigger port-up-send enable command does not take effect.
Procedure
- Run system-view
