ERPS Feature Limitations
The following are ERPS (Ethernet Ring Protection Switching) feature
limitations:
- Backup failover and checkpointing for both v1 and v2 are not available
in the current release.
- In platforms that do not have hardware OAM (operations and
management), the optimum CFM interval recommended is one second for link monitoring, which
will give rise to approximately three-second overhead in convergence times.

Note
For optimum
performance and convergence, it is recommended to use fiber cables.
- Other than the basic EAPS (Extreme Automatic Protection Switching)
interoperability stated above, all other EAPS related interoperability is not
supported.
- There is no interoperability with STP (Spanning Tree Protocol) in
the current release.
