For each ring, a protection group must be configured. There may be several rings in each
node, so there should be multiple protection groups corresponding to the related Ethernet
rings.
Three interval parameters (restore-interval, guard-interval, and hold-interval) can be
configured at the protection group level. These configurations are global configurations
and apply to all Ethernet rings if the Ethernet ring doesn't have a more specific
configuration for these values. If no parameter is configured at the protection group level,
the global configuration of this parameter uses the default value.
