Ethernet Ring Protection (ERP) 

This chapter describes the Ethernet Ring Protection functionality based on G.8032v2. 

 

ERP is a licensed feature that requires license for operation. Before configuring it, verify 
that license is available and enable the 

L2 (resiliency

) license component. 

12.1 

Ethernet Ring Protection Description 

Ethernet Ring Protection (ERP) is a network resiliency protocol defined in ITU -T G.8032. 
The EtherHaul supports ERP G.8032v2, with backwards compatibility to previous 
versions. ERP support enables protection for any point of failure in the network. This 
means that network connectivity is maintained in the event that the Ethernet link, the 
radio link, or even the entire EtherHaul fails. This provides resiliency for both Ethernet -
Ethernet rings that typically protect single site connectivity and Ethernet-RF rings that 
typically protect against RF network failure. 

ERP is a relatively simple protocol that operates at the network level on the set of nodes 
that constitute the ring or set of rings. ERP monitors the Ethernet layer to discover and 
identify Signal Failure (SF) conditions, and prevents loops within the ring by blocking 
one of the links (either a pre-determined link or a failed link). ERP verifies at all times 
the ring is closed that frames will not be looped. This is accomplished by ta king down a 
Ring protection Link (RPL) whenever there is no failure in the ring. 

Using ERP, EtherHaul provides protection and recovery switching within 50 mSec for 
typical rings. The ERP mechanism uses a very small percentage of total available 
bandwidth. 

The following figure illustrates the basic ERP protection mechanism. In normal ring 
operation, the RPL is blocked. In a failure condition, the failed link is blocked, R-APS 
messages are sent from the nodes adjacent to the failed links in order to unblock t he 
RPL, and an FDB flush is performed on all ring nodes as necessary. 

Note:

 

 

ERP configuration and monitoring supported in the CLI only.
