Command Reference
Remembering the interface numbering convention mentioned earlier, you could
know that the name of a physical interface is represented by interface type + interface
number. For example, Ethernet0/0/0 represents the Ethernet interface numbered
0/0/0, and Serial0/0/0.1 the first subinterface on the interface Serial0/0/0, and
interface Serial3/0/0:2 the second channel set of the CE1/PRI interface (namely
controller interface) numbered 3/0/0.
The name of a logical interface is represented by interface type + interface number,
for example, tunnel 0.
You can however shorten the type portion in the interface name by inputting only the
leading conflict-free letters, for example, e0/0/0 for Ethernet 0/0/0 and s0/0/0.1 for
Serial 0/0/0.1.
You can enter the view of the desired physical interface and create logical interfaces
or subinterfaces as needed by executing the
interface command.
You can create subinterfaces for an Ethernet interface or a serial interface
encapsulated with X.25 or Frame Relay (FR). The subinterface numbered 0 is the
actually corresponding main interface.
Note that executing the undo interface command deletes the defined logical
interfaces (such as Dialer, tunnel, and virtual-template interfaces) and subinterfaces.
