Interface status

Interface status is a monitoring indicator that

  • shows the current operational state of monitored interfaces in a failover configuration

  • tracks traffic reception and hello packet communication between peer units, and

  • determines whether an interface is actively monitored by the failover process.

Interface status types

Monitored interfaces can have these status types:

  • Unknown: Initial status. This status can also mean the status cannot be determined.

  • Normal: The interface is receiving traffic.

  • Normal (Waiting): The interface is up, but has not yet received a hello packet from the corresponding interface on the peer unit.

  • Normal (Not-Monitored): The interface is up, but is not monitored by the failover process.

  • Testing: Hello messages are not heard on the interface for five poll times.

  • Link Down: The interface or VLAN is administratively down.

  • Link Down (Waiting): The interface or VLAN is administratively down and has not yet received a hello packet from the corresponding interface on the peer unit.

  • Link Down (Not-Monitored): The interface or VLAN is administratively down, but is not monitored by the failover process.

  • No Link: The physical link for the interface is down.

  • No Link (Waiting): The physical link for the interface is down and has not yet received a hello packet from the corresponding interface on the peer unit.

  • No Link (Not-Monitored): The physical link for the interface is down, but is not monitored by the failover process.

  • Failed: No traffic is received on the interface, yet traffic is heard on the peer interface.
