Table 10 defines the port flap dampening statistics displayed by the show link-error-disable all command.

TABLE 10	Output of show link-error-disable
Column		Description
Port #		The port number.
Threshold		The number of times the port link state will go from up to down and
		down to up before the wait period is activated.
Sampling-Time		The number of seconds during which the specified toggle threshold can
		occur before the wait period is activated.
Shutoff-Time		The number of seconds the port will remain disabled (down) before it
		becomes enabled. A zero (0) indicates that the port will stay down until
		an administrative override occurs.
State		The port state can be one of the following:
		• Idle – The link is normal and no link state toggles have been
		detected or sampled.
		• Down – The port is disabled because the number of sampled errors
		exceeded the configured threshold.
		• Err – The port sampled one or more errors.
Counter		• If the port state is Idle, this field displays N/A.
		• If the port state is Down, this field shows the remaining value of the

shutoff timer.

• If the port state is Err, this field shows the number of errors sampled.

Syntax: show link-error-disable [all]

Syslog messages for port flap dampening

The following Syslog messages are generated for port flap dampening.

•If the threshold for the number of times that a port link toggles from “up” to “down” then “down” to “up” has been exceeded, the following Syslog message is displayed.

0d00h02m10s:I:ERR_DISABLE: Link flaps on port ethernet 16 exceeded threshold; port in err-disable state

•If the wait time (port is down) expires and the port is brought up the following Syslog message is displayed.

0d00h02m41s:I:ERR_DISABLE: Interface ethernet 16, err-disable recovery timeout
