Interface Commands 4

•If autonegotiation is disabled, auto-MDI/MDI-X pin signal configuration will also be disabled for the RJ-45 ports.

Example

The following example configures port 11 to use autonegotiation.

Console(config)#interface ethernet 1/11

Console(config-if)#negotiation

Console(config-if)#

capabilities

This command advertises the port capabilities of a given interface during autonegotiation. Use the no form with parameters to remove an advertised capability, or the no form without parameters to restore the default values.

Syntax

[no] capabilities {1000full 100full 100half 10full 10half flowcontrol symmetric}

•1000full - Supports 1000 Mbps full-duplex operation

•100full - Supports 100 Mbps full-duplex operation

•100half - Supports 100 Mbps half-duplex operation

•10full - Supports 10 Mbps full-duplex operation

•10half - Supports 10 Mbps half-duplex operation

•flowcontrol - Supports flow control

•symmetric (Gigabit only) - When specified, the port transmits and receives pause frames; when not specified, the port will auto-negotiate to determine the sender and receiver for asymmetric pause frames. (The current switch ASIC only supports symmetric pause frames.)

Default Setting

•100BASE-TX: 10half, 10full, 100half, 100full

•1000BASE-T: 10half, 10full, 100half, 100full, 1000full

•SFP: 1000full

Command Mode

Interface Configuration (Ethernet, Port Channel)

Command Usage

When auto-negotiation is enabled with the negotiation command, the switch will negotiate the best settings for a link based on the capabilites command. When auto-negotiation is disabled, you must manually specify the link attributes with the speed-duplexand flowcontrol commands.
