Configuring MultiGigabit Ports on WS-X4748-12X48U+E
This example shows how to select Gigabit Ethernet interfaces on a WS-X4606-10GE-E using the TwinGig Convertor:
Switch# config terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# hw-module module 1 port-group 1 select gigabitethernet
Switch(config)# exit
Switch# show int status mod 1
Port Name Status Vlan Duplex Speed Type
Te1/1 inactive 1 full 10G No X2
Te1/2 inactive 1 full 10G No X2
Te1/3 inactive 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 notconnect 1 full 1000 No Gbic
Gi1/8 notconnect 1 full 1000 No Gbic
Gi1/9 notconnect 1 full 1000 No Gbic
Gi1/10 notconnect 1 full 1000 No Gbic
Gi1/11 notconnect 1 full 1000 No Gbic
Gi1/12 notconnect 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
Configuring MultiGigabit Ports on WS-X4748-12X48U+E
Cisco’s Multigigabit Ethernet technology allows you to leverage 802.11ac Wave 2 speeds on your device. Beginning in Cisco
IOS XE Release 3.7.1E, you can configure the WS-X4748-12X48U+E module to auto-negotiate multiple speeds on switch
ports, and support 100 Mbps, 1 Gbps, 2.5 Gbps, and 5 Gbps speeds on Category 5e cables, and up to 10 Gbps over Category 6
and Category 6a cables. For more information on supported cables, see Supported Cable Types and Speed, page 9-17.
Beginning in Cisco IOS XE 3.9.1E, by default, downshift is enabled on multigigabit ports. When an interface is unable to
establish a high speed link, the line rate is automatically downshifted or reduced to a lower speed. The interface tries up to four
times to reestablish a link using the current speed, before downshifting to the next available lower speed. Multigigabit
interfaces support downshifting only when the interface speed is set to auto on both sides of the link. For information about
enabling downshift on WS-X4748-12X48U+E, see Setting Multigigabit Ethernet Interface Speeds, page 9-29.

Step 3
Switch(config)# exit
Exits configuration mode.
Step 4
Switch# show int status mod n
Verifies the setting.
