NOTE
When automatic recovery re-enables the port, the port is not in the error-disabled state, but it can
remain down for other reasons, such as the Tx/Rx of the fibre optic not being seated properly. Thus, the
port is not able to receive the signal from the other side. In this case, after the optic is inserted correctly,
you should manually disable the port and then enable it.
Enabling an error-disabled port manually
To enable an error-disabled port manually, you must first run the disable command and then the
enable command in interface configuration mode to disable the port and then enable the port
respectively.
Setting the recovery interval
The errdisable recovery interval command allows you to configure a timeout for ports in the error-
disabled state, after which the ports are re-enabled automatically. To set the error-disabled recovery
timeout interval, enter the following command:
Brocade(config)# errdisable recovery interval 20
Syntax: [no] errdisable recovery interval seconds
The seconds variable allows you to set the timeout value for the recovery mechanism when the port is
in an errdisabled state. Once this timeout value expires, the ports are automatically re-enabled. Valid
values are from 10 through 65535 seconds.
Displaying the error disable recovery state by interface
The port status of errdisabled displays in the output of the show interface and the show interface
brief commands. In this example, errdisable is enabled on interface ethernet 1 and errdisable is
enabled because of a BPDU guard violation.
device#show interfaces ethernet 1
GigabitEthernet1 is ERR-DISABLED (bpduguard),
line protocol is down
BPDU guard is Enabled, ROOT protect is Disabled
