Associating Track with ERPS
About Track association with ERPS
To detect and clear link faults typically for a fiber link, use ERPS with CFD and Track. You can associate ERPS ring member ports with the continuity check function of CFD through track entries. CFD reports link events only when the monitored VLAN is the control VLAN of the ERPS instance for the port.
Track changes the track entry state based on the monitoring result of CFD, and notifies the track entry state change to the associated EPRS ring.
When the track entry is in Positive state, the link of the monitored ERPS ring member port is in normal state. The ERPS ring does not switch traffic to other links.
When the track entry is in Negative state, the link of the monitored ERPS ring member port is faulty. The ERPS ring switches traffic to other links.
When the track entry is in NotReady state, the state of the ERPS ring member port does not change.
For more information about ERPS, see "Configuring ERPS."
Restrictions and guidelines
Before you associate a port with a track entry, make sure the port has joined an ERPS instance.
