Interface Commands

4-223

4

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-duplex and flowcontrol commands.

Example

The following example configures Ethernet port 25 capabilities to 100half, 100full
and flow control.

Console(config)#interface ethernet 1/25
Console(config-if)#capabilities 100half
Console(config-if)#capabilities 100full
Console(config-if)#capabilities flowcontrol
Console(config-if)#
