with the new uplink mode into flash memory, the uplink mode must be changed to the new uplink mode
through the command interface before the system is power cycled. This ensures that the system comes
up in the new uplink mode.
The following example shows how to enable both 10-Gigabit Ethernet and Gigabit Ethernet SFP uplink
ports on a Catalyst 4510R series switch:
Switch# configure terminal
Switch(config)# hw-module uplink select all
Warning: This configuration mode will place slot 10 in flex slot mode
Note When you modify the uplink mode, you must reboot the switch.
Deploying 10-Gigabit Ethernet or Gigabit Ethernet Ports on Supervisor Engine 6-E, Supervisor Engine 6L-E and WS-X4606-X2-E
To increase the flexibility of X2 ports on the Supervisor Engine 6-E, Supervisor Engine 6L-E, and
WS-X4606-X2-E, the Catalyst 4500 series switch as well as Catalyst 4900M and Catalyst 4948E support
TwinGig Convertor modules. When you plug a TwinGig Convertor module into an X2 hole, it converts
a single X2 hole (capable of holding one pluggable X2 optic) into two SFP holes (capable of holding
two pluggable SFP optics). This enables you to have 10-Gigabit ports and 1-Gigabit ports on the same
line card. It also allows you to use Gigabit ports, and then switch to a 10-Gigabit port, when needed.

Port Numbering TwinGig Convertors

When a TwinGig Convertor is enabled or disabled, the number and type of ports on the line card change
dynamically. The terminology must reflect this behavior. In Cisco IOS, 10-Gigabit ports are named
10-Gigabit and 1-Gigabit ports are named Gigabit. Starting with Cisco IOS Release 12.2(40)SG, to
avoid having two ports named 10-Gigabit1/1 and Gigabit1/1, the 10-Gigabit and 1-Gigabit port number s
are independent. For example, for a WS-X4606-X2-E module with six X2 holes, the X2 ports are named
10-Gigabit slot-num/<1-6>, and the SFP ports are named Gigabit slot-num/<7-18>.
