Usage Guidelines To enable system logging of interface state-change events on a specific interface, enter the
logging event trunk-status command in interface configuration mode.
To enable system logging of interface state-change events on all interfaces in the system, enter the
logging event trunk-status use-global command in global configuration mode. All interfaces without
the state change event configuration use the global setting.
Examples This example shows how to enable logging event state-change events on interface gi11/1:
Switch# config terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# interface gi11/1
Switch(config-if)# logging event trunk-status
Switch(config-if)# end
Switch#
This example shows how to turn off logging event trunk status regardless of the global setting:
Switch# config terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# interface gi11/1
Switch(config-if)# no logging event trunk-status
Switch(config-if)# end
Switch#
