Configuring Ethernet Ring Protection Switching

[Contents] [Prev] [Next] [Index] [Report an Error]

The inheritance model follows:



protection-group {



ethernet-ring ring-name (



east-interface {



control-channel channel-name{
vlan number;
}


}



guard-interval number;

node-id mac-address;

restore-interval number;

ring-protection-link-owner;



west-interface {



control-channel channel-name {
vlan number;
}


}


}


}

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.
