Pre-configuration
Nearly all switch features support a pre-configuration capability, even when a
feature is not enabled or the required hardware is not present.
Pre-configured capabilities become active only when enabled (typically via an
admin mode control) or when the required hardware is present (or both). For
example, a port can be pre-configured with both trunk and access mode
information. The trunk mode information is applied only when the port is
placed into trunk mode and the access mode information is only applied
when the port is placed into access mode. Likewise, OSPF routing can be
configured in the switch without being enabled on any port.
Interface Configuration Modes
Interface configuration modes are used to modify specific interface
operations. The following are the Interface Configuration and other specific
configuration modes:
•
Ethernet — Contains commands to manage Ethernet port configuration.
The Global Configuration mode command interface interface-id enters
the Interface Configuration mode to configure an Ethernet interface.
•
Port Channel — Contains commands to configure port-channels, i.e.,
assigning ports to a port-channel. Most of these commands are the same as
the commands in the Ethernet interface mode and are used to manage the
member ports as a single entity. The Global Configuration mode
command interface port-channel port-channel-number is used to enter
the Port Channel mode.
Tunnel — Contains commands to manage tunnel interfaces. The Global

Loopback — Contains commands to manage loopback interfaces. The
Global Configuration mode command interface loopback enters the
Loopback Configuration mode to configure an loopback type interface.
•
Out-of-band—Contains commands to manage the out-of-band interface,
if present. The Global Configuration mode command interface out-of-
band enters the Out-of-band Interface mode to configure the out-of-band
interface.
