Usage Guidelines
In the output for the show interface rep [detail] command, in addition to an Open, Fail, or AP (alternate
port) state, the Port Role might show as Fail Logical Open (FailLogOpen) or Fail No Ext Neighbor
(FailNoNbr). These states indicate that the port is physically up, but REP is not configured on the
neighboring port. In this case, one port goes into a forwarding state for the data path to help maintain
connectivity during configuration. The Port Role for this port shows as Fail Logical Open; the port
forwards all data traffic on all VLANs. The other failed Port Role shows as Fail No Ext Neighbor; this
port blocks traffic for all VLANs.
When the external neighbors for the failed ports are configured, the failed ports go through the alternate
port state transitions and eventually go to an Open state or remain as the alternate port, based on the
alternate port election mechanism.
