snmp trap link-status suppress
Use this command to enable the suppression of link status notifications (traps) for the
interfaces beyond the specified threshold, in the specified interval. Use the no variant of
this command to disable the suppression of link status notifications for the ports.
Syntax snmp trap link-status suppress
{time {<1-60>|default}|threshold {<1-20>|default}}
no snmp trap link-status suppress
Default By default, if link status notifications are enabled (they are enabled by default), the
suppression of link status notifications is enabled: notifications that exceed the
notification threshold (default 20) within the notification timer interval (default 60
seconds) are not sent.
Mode Interface Configuration
Usage An unstable network can generate many link status notifications. When notification
suppression is enabled, a suppression timer is started when the first link status notification
of a particular type (linkUp or linkDown) is sent for an interface. If the threshold number of
notifications of this type is sent before the timer reaches the suppress time, any further
notifications of this type generated for the interface during the interval are not sent. At the
end of the interval, the sending of link status notifications resumes, until the threshold is
reached in the next interval.
Examples To enable the suppression of link status notifications for ports 1.0.2 to 1.0.6 after 10
notifications have been sent in 40 seconds, use following commands:
To disable the suppression link status notifications for port 1.0.2, use following commands:
