Chapter 9 Configuring Interfaces
Deploying 10-Gigabit Ethernet or Gigabit Ethernet Ports
Selecting X2/TwinGig Convertor Mode
The default configuration mode is X2. If you plan to deploy 10-Gigabit Ethernet interfaces, you do not need to configure
anything. However, if you want to deploy Gigabit interfaces (that is, use TwinGig Convertors), you must configure the
associated port-group:
To determine how the X2 holes on a module are grouped, enter the show hw-module module m port-group p command.
Note Place a 10-Gigabit Ethernet port that accepts CVR-X2-SFP into 1-Gigabit mode instead of 10-Gigabit Ethernet mode.
If you configure a 10-Gigabit Ethernet port as 1-Gigabit port, an output similar to the following appears:
Switch# show hw-module module 5 port-group
Module Port-group Active Inactive
-------------------------------------------------------------
5 1 Gi5/3-6 Te5/1-2
If the port is set to the default, 10-Gigabit Ethernet mode, an output similar to the following appears:
Switch# show hw-module module 6 port-group
Module Port-group Active Inactive
-------------------------------------------------------------
6 1 Te6/1-2 Gi6/3-6
Switch# show int status mod 1
Port Name Status Vlan Duplex Speed Type
Te1/1 notconnect 1 full 10G 10GBase-LR
Te1/2 connected 1 full 10G 10GBase-LR
Te1/3 notconnect 1 full 10G No X2
Te1/4 notconnect 1 full 10G No X2
Te1/5 notconnect 1 full 10G No X2
Te1/6 notconnect 1 full 10G No X2
Gi1/7 inactive 1 full 1000 No Gbic
Gi1/8 inactive 1 full 1000 No Gbic
Gi1/9 inactive 1 full 1000 No Gbic
Gi1/10 inactive 1 full 1000 No Gbic
Gi1/11 inactive 1 full 1000 No Gbic
Gi1/12 inactive 1 full 1000 No Gbic
Gi1/13 inactive 1 full 1000 No Gbic
Gi1/14 inactive 1 full 1000 No Gbic
Gi1/15 inactive 1 full 1000 No Gbic
Gi1/16 inactive 1 full 1000 No Gbic
Gi1/17 inactive 1 full 1000 No Gbic
Gi1/18 inactive 1 full 1000 No Gbic
Switch#
• To configure the modes of operation for each X2 port group in which you want to deploy Gigabit, enter the hw-module
module m port-group p select gigabitethernet command. This configuration is preserved across power cycles and
reloads.
To deploy Gigabit Ethernet interfaces using the TwinGig Convertor, perform this task:
Command Purpose
Step 1
Switch# configure terminal
Establishes global configuration mode.
Step 2
Switch(config)# hw-module module m port-group p
select [gigabitethernet | tengigabitethernet]
Selects the mode of operation for each X2 port-group.
Default is 10-Gigabit Ethernet (x2).
