Interfaces Violation Recovery

The OmniSwitch allows features to shutdown an interface when a violation occurs on that interface. To
support this functionality, the following interfaces violation recovery mechanisms are provided:
•
Manual recovery of a downed interface using the
•
An automatic recovery timer that indicates how much time a port remains shut down before the switch
automatically brings the port back up (see
•
A maximum number of recovery attempts setting that specifies how many recoveries can occur before
a port is permanently shutdown (see
•
A wait-to-restore timer that indicates the amount of time the switch waits to notify features that the
port is back up (see
•
An SNMP trap that is generated each time an interface is shutdown by a feature. This can occur even
when the interface is already shutdown by another feature. The trap also indicates the reason for the
violation.
•
An SNMP trap that is generated when a port is recovered. The trap also includes information about
how the port was recovered. Enabling or disabling this type of trap is allowed using the
recovery-trap command.

Violation Shutdown and Recovery Methods

A port can be shutdown with one of the following methods, depending on the feature.
Filtering – The port is blocked by applying filtering to discard all packets sent or received on the port.
With this method the link LED of the port remains ON. A port in this state can be recovered using the
following methods:
•
Using the interfaces split-mode
•
Automatic recovery when the interface recovery timer expires.
•
Using the interfaces alias
•
Disconnecting and reconnecting the interface link.
•
A link down and link up event.
Administratively – A port is administratively disabled. With this method the LED does not remain ON. A
port in this state can be recovered using only the following methods:
•
Using the interfaces split-mode
•
Automatic recovery when the interface recovery timer expires.
•
Using the interfaces alias
Disconnecting/reconnecting the interface link or a link down/up event will not recover a port that was
administratively disabled.
