Port groups for configuring operation modes are illustrated in the following figure. If you configure a
port group in Performance mode, the first two ports in a group are enabled for Performance mode. The
third port is disabled as it can only be configured in density mode only. I If you configure the port group
in Density mode, all three ports are enabled for density mode. To identify the port group, use the
format rbridge-id/slot-id/port group-id. For example, 1/3/9 denotes RBridge 1, slot 3, and port-group-id
9.

To configure Performance and Density modes for line card port groups using Network OS commands,
refer to 27x40 GbE operating modes.
High availability
High availability is currently limited to management module configuration synchronization. Failover to
the standby module will occur in case of active module failure, but the standby module will go through
a cold recovery in which all system components are reset. This will disrupt traffic on the chassis. The
reset could take up to eight minutes depending on chassis configuration and traffic load.
