ERPS Feature Limitations
  
  
    The following are ERPS 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
        interoperability stated above, all other EAPS related interoperability is not
        supported.
- There is no interoperability with STP in
        the current release.
