Command Usage
The EAN redundancy is achieved by using EDN312x (containing two 100
Mbps uplinks) and an expansion kit. The expansion kit contains an extra
ECN. One ECN is configured as Active, while the other ECN is configured
as Standby. During normal operation, all data and management traffic goes
through the active ECN. When either the active ECN, the uplink connecting
it to the network, or the link between the ECN and the EDN312x fails, the
EDN312x will go over to unmanaged state, and all the End-user data will be
directed through the standby ECN.
Note: Rapid Spanning Tree (RSTP) must be enabled in both ECN for re-
dundancy to work. One must be standby and the other active.
Example
ecn330(config)# ecn redundancy work-mode standby
