Overview of MultiGigabit Ports

Cisco’s Multigigabit Ethernet technology allows you to leverage 802.11ac Wave 2 speeds on your device. Beginning with Cisco IOS XE 3.7.E1 and IOS 15.2(3) E1, you can configure the WS-C3560CX-8XPD-S 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 Category6 and Category 6A cables.

The WS-C3560CX-8XPD-S module has 8 ports, of which the 6 ports are 1-Gigabit Ethernet ports and 2 ports are the Multi-Gigabit ports. The module also has 2 SFP+ ports.

Restrictions for MultiGigabit Ports

The following restrictions apply:

  • MultiGigabit ports do not support 10Mbps speed.

  • MultiGigabit ports do not support half-duplex mode.

  • MultiGigabit ports do not support EEE.

Setting the Interface Speed

To set port speed to 100Mbps/1000Mbps/2500Mbps/5000Mbps/10000Mbps on a Multigigabit Ethernet interface (on a 1000Base-T port), perform this task:


Note

Only 2 ports on the WS-C3560CX-8XPD-S module support Multigigabit Ethernet.

SUMMARY STEPS

  1. enable
  2. configure terminal
  3. interface tengigabitethernet slot/interface
  4. speed [100 | 1000 | 2500 | 5000 | 10000 | auto [100 | 1000 | 2500 | 5000 | 10000 ]]
  5. end

DETAILED STEPS

  Command or Action Purpose
Step 1

enable

Example:


Switch> enable

Enables privileged EXEC mode.

  • Enter your password if prompted.

Step 2

configure terminal

Example:


Switch# configure terminal

Enters global configuration mode.

Step 3

interface tengigabitethernet slot/interface

Example:

Switch(config)# interface tengigabitethernet 1/0/2

Specifies the interface to be configured.

Step 4

speed [100 | 1000 | 2500 | 5000 | 10000 | auto [100 | 1000 | 2500 | 5000 | 10000 ]]

Example:

Switch (config-if)# speed 5000

Sets the interface speed.

Note 
10G speed is supported only on Category6 and Category6A cables.
Step 5

end

Example:


Switch(config)# end

Returns to privileged EXEC mode.

What to do next

To restore autonegotiation (default setting), enter the no speed command in the interface configuration mode.

Examples: Setting the Interface Speed

This example shows how to set the interface speed to 5G on the Multigigabit Ethernet interface 1/0/2: 
Switch(config)# interface tengigabitethernet 1/0/2
Switch (config-if)# speed 5000
This example shows how to allow the Multigigabit Ethernet interface 1/0/2 to autonegotiate the speed and duplex mode: 
Switch(config)# interface tengigabitethernet 1/0/2
Switch(config-if)# speed auto
This example shows how to limit speed negotiation to 2.5G on the Multigigabit Ethernet interface 1/0/1: 
Switch(config)# interface tengigabitethernet 1/0/1
Switch(config-if)# speed auto 2500
