RingV2 with ERPSNEW!

Although RingV2 cannot be used concurrently with Ethernet Ring Protection Switching (ERPS), you might need to configure ERPS if your ISW ring will interact with rings on other platforms. ExtremeXOS (EXOS) switches can run with ERPS, for example, and so can some switches from other manufacturers.

When configuring a RingV2 ISW switch to interact with an EXOS switch running ERPS, keep the following principles in mind:
  • The key to connecting RingV2 rings with ERPS rings is ensuring that configuration parameters align in both systems.
  • ISW default values for some timings (associated with recovery of the ring) do not match EXOS defaults.
  • Some ISW variables have a different accepted variable length than the equivalent variables in EXOS.
  • Carefully test your configuration, using logs and other troubleshooting tools to understand ways in which the settings interact with each other.
