ERPS Ring ID-Based Control MAC

R-APS control MAC

The R-APS messages uses the MAC address range allocated within ITU OUI for G.8032 R-APS communication, which is 01:19:A7:00:00:ring-id or 01:19:A7:00:00:01, where ring-id ranges from 1 to 239. ExtremeXOS supports both types of R-APS control MACs. You can use either “01:19:A7:00:00:01 (auto)” or “01:19:A7:00:00:ring-id (default)” as R-APS control MAC using the command configure erps ring-name control-mac[auto | default]). Note that this command is only applicable on ring instances created with a user-defined ring ID.

Control MAC by default:

If the ERPS ring is created with a user-defined ring ID, then the control MAC used by the ring will be “01:19:A7:00:00:ring-id (control-mac type auto)” by default.
If the ERPS ring is created without user-defined ring ID, then the control MAC used by ring will be “01:19:A7:00:00:01(control-mac type default)” by default.
If you are upgrading ExtremeXOS from an older version (without ring ID-based control MAC support) to a newer version (with ring ID-based control MAC support), all configurations are retained and unique ring IDs will be assigned to those ERPS ring instances by default. The R-APS control MAC used by these rings is “01:19:A7:00:00:01 (default)” by default. Note that control MAC configuration as "auto" is not applicable on such ring instances.

Be advised, the ITU_T standard does not have the mechanism to recognize configuration mismatches across the nodes, especially with the ring ID/control MAC configuration, so it is up to the user to ensure that the all ring instances on all nodes within the same physical ring have the same ring ID and control MAC.
