Configuring operating modes on 27x40 GbE line cards
3
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.
Please save the running-config to startup-config and a power-cycle for the
changes to take place.
7. Exit port group configuration mode.
switch(config-port-group-1/3/9)# exit
8. Exit hardware configuration mode.
switch(config-hardware)# exit
9. Exit global configuration mode.
switch(config)# exit
switch#
10. Power on the line card.
switch# power-on linecard 3
Displaying operating modes
To display the current operating mode for a specific port group, use the show running-config
hardware port-group rbridge-id/slot-id/port group-id command. 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.
