Configuring MAC Authentication Bypass
This example shows how to enable MAC authentication bypass on a port:
Console> (enable) set port mac-auth-bypass 3/1 enable
MAC-Auth-Bypass successfully enabled on 3/1.
Console> (enable)
Initializing the MAC Authentication Bypass State for a Port
To initialize the MAC authentication bypass state for a port so that the port can participate in
authentication again, perform this task in privileged mode:
Task
Initialize the MAC authentication bypass state for a port so
the port can participate in authentication again.
This example shows how to initialize the MAC authentication bypass state for a port so that the port can
participate in authentication again:
Console> (enable) set port mac-auth-bypass 3/1 initialize
Mac-Auth-Bypass successfully Initialized 3/1.
Console> (enable)
Reauthenticating the MAC Address for a Port
To reauthenticate the MAC address for a port, perform this task in privileged mode:
Task
Reauthenticate the MAC address for a port.
This example shows how to reauthenticate the MAC address for a port:
Console> (enable) set port mac-auth-bypass 3/1 reauthenticate
Reauthenticating MAC address 00-00-00-00-00-01 on port 3/1 using Mac-Auth-Bypass.
Console> (enable)
Specifying the Shutdown Timeout Period
If there is a security violation on a port, the port shuts down. Use the global set mac-auth-bypass
shutdown-timeout seconds command to specify the time (in seconds) the ports are shut down before
they are automatically reenabled. The range is from 30 to 65535 seconds. The default is 60 seconds. If
you specify a shutdown timeout period of 0 seconds, the automatic port enable function is disabled and
you will have to reenable the ports manually.
