Rings

Ethernet Ring Protection (ERP) uses rings. An ERP ring can be configured only on ring topologies with all ports having same port encapsulation types which includes .1q and .1ad. A Ringlet is a part of a ring and contains the set of VLANs in the ring which needs to be protected. Rings explained in this section are about ERP (G.8032) rings.

To view the rings option, go to Configuration > Layer 2 menu and click Rings option. The Rings page is displayed.

NOTE: Topology needs to be selected before provisioning rings. Topology can be created by provisioning static/dynamic packet trunks from node. Topology can also be created by provisioning offline packet trunks from TJ5100 EMS. For more details refer TJ5100 User Interface Guide of this release.

The ELINE service which is created automatically on the node by creating a Ring or Ringlet will not be discovered in TJ5100/TJ5500 as this EVC is not part of any Services.
