ERPS Feature Limitations
  
  
    The following are ERPS feature limitations:
    
      - Backup MSM 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.
 
      - SNMP is not supported in the current release.
