Configure this parameter to enable a timer that brings a port out of the disabled state.
These parameters are be set in STP, RSTP, MSTP, PVST+, and R-PVST+.
When the STP BPDU guard disables a port, the port remains in the disabled state unless the port is enabled manually. The parameter specifies the time in seconds it takes for an interface to time out. The range is from 10 through 1000000 seconds. The default is 300 seconds.
By default, the timeout feature is disabled.
