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.

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.
