Ethernet Ring Protection Protocol
displays the Brocade devices and the Ethernet Ring Protection (ERP) features they
support.
Ethernet Ring Protection
Ethernet Ring Protection (ERP), a non-proprietary protocol described in ITU-T G.8032 (Version 1 and
2), integrates an Automatic Protection Switching (APS) protocol and protection switching
mechanisms to provide Layer 2 loop avoidance and fast reconvergence in Layer 2 ring topologies.
ERP supports multi-ring and ladder topologies. ERP can also function with IEEE 802.1ag to support
link monitoring when non-participating devices exist within the Ethernet ring.
You can enable one instance of ERP on a device. Changes to a master VLAN apply to the member
VLANs.
