Usage Guidelines A cause (all, bpduguard and so forth) is defined as the reason why the error-disabled state occurred.
When a cause is detected on an interface, the interface is placed in error-disabled state, an operational
state similar to link-down state. If you do not enable errdisable recovery for the cause, the interface stays
in error-disabled state until you enter a shutdown and no shutdown interface configuration command.
If you enable the recovery for a cause, the interface is brought out of the error-disabled state and allowed
to retry the operation again when all the causes have timed out.
Otherwise, you must enter the shutdown then no shutdown commands to manually recover an interface
from the error-disabled state.
Examples This example shows how to enable the recovery timer for the BPDU guard error-disable cause:
Switch(config)# errdisable recovery cause bpduguard
78-16181-03
Enable the timer to recover from the VLAN Membership Policy Server
(VMPS) error-disable state.
Specify the time to recover from the specified error-disable state. The range
is 30 to 86400 seconds. The same interval is applied to all causes. The default
interval is 300 seconds.
The errdisable recovery timer is initialized at a random differential
Note
from the configured interval value. The difference between the actual
timeout value and the configured value can be up to 15 percent of the
configured interval.
