5. Enter the port-group command to enter configuration mode for a specific port group.
There are nine port groups on the line card. To identify the port group, use the format
rbridge-id/slot-id/port group-id.
switch(config-hardware)# port-group 1/3/9
6. Perform one of the following steps:
• Enter the mode performance command to configure Performance mode for the port group.
switch(config-port-group-1/3/9)# 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.
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.
switch(config-port-group-1/3/9)# no mode performance
%Warning: port-group mode performance is a disruptive command.

Saving your changes
Complete the following steps to make your changes persistent. This ensures that if you must reboot
the switch, the preferences you have set will be in force when the switch comes back up.
1. Log in to the switch using an account that has the admin role.
2. In privileged EXEC mode, enter the copy running-config startup-config command.
switch# copy running-config startup-config
This operation will modify your startup configuration. Do you want to
continue? [Y/N]: Y
3. When the confirmation question appears, answer Y for Yes.
The current running configuration, containing all of your latest changes, is saved to the startup
configuration. The next time the switch reboots, all of the changes will remain in force.
