errdisable detect cause
To enable error-disable (err-disabled) detection in an application, use the errdisable detect cause command. To disable error disable detection, use the no form of this command.
errdisable detect cause { all | link-flap | loopback }
no errdisable detect cause { all | link-flap | loopback }
Syntax Description
|
all |
Enables error detection on all cases. |
|
link-flap |
Enables error disable detection on linkstate-flapping. |
|
loopback |
Enables error disable detection on loopback. |

Usage Guidelines
When error disable detection is enabled and a cause is detected on an interface, the interface is placed in an err-disabled state, which is an operational state that is similar to the link-down state.
Examples
This example shows how to enable the err-disabled detection on linkstate-flapping:
switch(config)# errdisable detect cause link-flap switch(config)#

errdisable recovery cause
To configure the application to bring the interface out of the error-disabled (err-disabled) state and retry coming up, use the errdisable recovery cause command. To revert to the defaults, use the no form of this command.

Usage Guidelines
When error disable recovery is enabled, the interface automatically recovers from the err-disabled state, and the device retries bringing the interface up.
Examples
This example shows how to enable error disable recovery from linkstate-flapping:
switch(config)# errdisable recovery cause link-flap switch(config)#

Usage Guidelines
When error disable recovery is enabled, the interface automatically recovers from the err-disabled state, and the device retries bringing the interface up.
The device waits 300 seconds to retry.
Examples
This example shows how to enable error disable recovery time interval to 100 seconds:
switch(config)# errdisable recovery interval 100 switch(config)#
