Configuring basic port parameters

Syntax: show link-error-disable [all]
Example
The line “Link Error Dampening” displays “Enabled” if port flap dampening is enabled on the port
or “Disabled” if the feature is disabled on the port. The feature is enabled on the ports in the two
examples above. Also, the characters “ERR-DISABLED” is displayed for the “GbpsEthernet” line if
the port is disabled because of link errors.
Syntax: show interface ethernet <port-number>
The ERR-DIS entry under the “Link” column indicates the port is down due to link errors.
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
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.
