The alias is displayed in the running-configuration file. An example of the
value which a network manager might store in this object for a WAN
interface is the (Telco's) circuit number/identifier of the interface.

The following example adds an alias to port 4.
Console(config)#interface ethernet 1/4

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.

◆
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.
