Usage Guidelines
In the default state, when you connect a supplicant switch to an authenticator switch that has BPCU guard
enabled, the authenticator port could be error-disabled if it receives a Spanning Tree Protocol (STP) bridge
protocol data unit (BPDU) packets before the supplicant switch has authenticated. Beginning with Cisco IOS
Release 15.0(1)SE, you can control traffic exiting the supplicant port during the authentication period. Entering
the
dot1x supplicant controlled transient
global configuration command temporarily blocks the supplicant
port during authentication to ensure that the authenticator port does not shut down before authentication
completes. If authentication fails, the supplicant port opens. Entering the
no dot1x supplicant controlled
transient
global configuration command opens the supplicant port during the authentication period. This is
the default behavior.
We strongly recommend using the
dot1x supplicant controlled transient
command on a supplicant switch
when BPDU guard is enabled on the authenticator switch port with the
spanning-tree bpduguard enable
interface configuration command.
Examples
This example shows how to control access to 802.1x supplicant ports on a switch during authentication:
