About the Error-Disabled State
An interface is in the error-disabled (err-disabled) state when the inteface is enabled administratively (using
the no shutdown command) but disabled at runtime by any process. For example, if UDLD detects a
unidirectional link, the interface is shut down at runtime. However, because the interface is administratively
enabled, the interface status displays as err-disabled. Once an interface goes into the err-disabled state, you
must manually reenable it or you can configure an automatic timeout recovery value. The err-disabled detection
is enabled by default for all causes. The automatic recovery is not configured by default.
When an interface is in the err-disabled state, use the errdisable detect cause command to find information
about the error.
You can configure the automatic err-disabled recovery timeout for a particular err-disabled cause by changing
the time variable.
The errdisable recovery cause command provides automatic recovery after 300 seconds. To change the
recovery period, use the errdisable recovery interval command to specify the timeout period. You can specify
30 to 65535 seconds.
If you do not enable the err-disabled recovery for the cause, the interface stays in the err-disabled state until
you enter the shutdown and no shutdown commands. If the recovery is enabled for a cause, the interface is
brought out of the err-disabled state and allowed to retry operation once all the causes have timed out. Use
the show interface status err-disabled command to display the reason behind the error.
Information About Port Profiles
Beginning with Cisco NX-OS Release 5.0(2)N1(1), you can create a port profile that contains many interface
commands and apply that port profile to a range of interfaces on the Cisco Nexus 5000 Series switch. Port
profiles can be applied to the following interface types:
• Ethernet
• VLAN network interface
• Port channel
