All (apply errdisable timeout for all of the above reasons)

You can enable or disable errdisable timeout for each of the above listed reasons. If you specify "other,"
all ports that are errdisabled by causes other than the reasons listed are enabled for errdisable timeout.
If you specify "all," all ports that are errdisabled for any reason are enabled for errdisable timeout.
The errdisable feature is disabled by default. The default interval for enabling a port is 300 seconds. The
allowable interval range is 30 to 86400 seconds (30 seconds to 24 hours).
To enable and configure the timeout period for ports in the errdisable state, perform these tasks in
privileged mode:
Task
Prevent a port from being reenabled at timeout
after it goes into the errdisable state.
Enable errdisable timeout for the BPDU guard
causes.
Enable errdisable timeout for all causes.
Set the errdisable timeout interval.
Display the errdisable timeout configuration.
This example shows how to prevent port 3/3 from being reenabled at timeout after it goes into the
errdisable state:
Console> (enable) set port errdisable-timeout 3/3 disable
Successfully disabled errdisable-timeout for port 3/3.
Console> (enable)
This example shows how to enable errdisable timeout for BPDU guard causes:
Console> (enable) set errdisable-timeout enable bpdu-guard
Successfully enabled errdisable-timeout for bpdu-guard.
Console> (enable)
This example shows how to enable errdisable timeout for all causes:
Console> (enable) set errdisable-timeout enable all
Successfully enabled errdisable-timeout for all.
Console> (enable)
This example shows how to set the errdisable timeout interval to 450 seconds:
Console> (enable) set errdisable-timeout interval 450
Successfully set errdisable timeout to 450 seconds.
Console> (enable)
