Configuring Port Redundancy
Overview
You can define two ports as a redundant pair. A redundant pair consists of a
primary and secondary port. Only one port is active at a time. In its normal
state in a redundant pair, the primary port transmits and receives data and
the secondary port is disabled, neither transmitting nor receiving data. The
secondary port does not perform load sharing. The primary and secondary
ports can be on different types of modules. For example, the primary port
can be 10/100 Ethernet and the secondary port can be Gigabit Ethernet.
Redundancy for ATM ports is not supported.

Redundancy for ATM ports is not supported.
If the primary port fails, the secondary port becomes the active port.
Failover time is less than 5 seconds. If the secondary port is the active port,
there is no change back to the primary port after it recovers. If both ports
fail, the first port to recover becomes the active port.

You can globally disable or enable redundancy pairs. When disabled, the
active port remains active and the disabled port remains disabled. When
port redundancy is enabled, the active port continues in that capacity. There
is no change to the primary port if the secondary port is the active port.
When you enable or disable redundancy pairs, you enable or disable all
active pairs.

A maximum of 20 pairs can be configured and active at any one time. You
must create a unique name for your pair. Port redundancy cannot be enabled
if Spanning Tree or Rapid Spanning Tree is enabled.
