Interface Commands

capabilities

This command advertises the port capabilities of a given interface during auto-negotiation. 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 1 Gbps 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 symmetric
pause frames.

Default Setting

1000BASE-T: 10half, 10full, 100half, 100full, 1000full
1000BASE-SX/LX/LH (SFP): 1000full

Command Mode

Interface Configuration (Ethernet, Port Channel)

Command Usage

•

The 1000BASE-T standard does not support forced mode. Auto-negotiation should always be
used to establish a connection over any 1000BASE-T port or trunk.

•

When auto-negotiation is enabled with the

negotiation

command, the switch will negotiate the

best settings for a link based on the capabilities command. When auto-negotiation is disabled,
you must manually specify the link attributes with the

speed-duplex

and

flowcontrol

commands.

Example

The following example configures Ethernet port 5 capabilities to include 100half and 100full.

Console(config)#interface ethernet 1/5
