Ethernet Ring Protection switching

The ITU G.8032 recommendation specifies a protection switching mechanism and protocol for
Ethernet layer network rings. Ethernet rings can provide wide-area multipoint connectivity and
redundancy more economically due to their reduced number of links. The mechanisms and
protocol defined in G.8032 achieve highly reliable and stable protection; and never form loops,
which would fatally affect network operation and service availability.

To configure Ethernet Protection Ring Switching (ERPS), follow the guidelines in the Brocade 6910
Ethernet Access Switch Configuration Guide
. If you encounter any problems, use the following
show command to display a summary of the configuration settings and operational status for all
rings, or detailed information for a specific ring.
