Installation guide

NOTE
Setting Performance mode shuts down the density-only port in the port group. The configuration is
allowed only when the slot is powered off and takes effect when the slot is powered on.
Enter the no mode performance command to configure Density mode for a port group already
configured for Performance mode.
device(config-port-group-1/3/9)# no mode performance
%Warning: port-group mode performance is a disruptive command.
Please save the running-config to startup-config and a power-cycle for the
changes to take place.

Displaying operating modes
To display the current operating mode for a specific port group, use the show running-config
hardware port-group command with the rbridge-id/slot-id/port group-id parameters. Note the
following responses:
• If "mode performance" displays, the port group is enabled in Performance mode.
• If "no mode performance" displays, the port group is enabled in Density mode.

The current running configuration, containing all of your latest changes, is saved to the startup
configuration. The next time the device reboots, all of the changes will remain in force.
