Parameter
type: Interface type. The following table lists the interfaces that VRP supports so
far.
number: Interface number. VRP numbers the interfaces separately by interface
type, with the numbers of each type of interfaces begin at 0 or 1.
sub-number: Subinterface number, which is separated from the main interface
number by a dot (“.”).
Description
Using the interface command, you can enter the specified interface view or create
a logical interface or subinterface. Using the undo interface command, you can
delete a specified logical interface or subinterface.
Table 2 Interfaces supported by VRP
An interface name 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 represents the first subinterface on the interface Serial0/0/0, and
interface Serial3/0/0:2 is the second channel set of the CE1/PRI interface (namely
controller interface) numbered 3/0/0.
To simplify input, the type portion of the interface name can be shortened to
several leading letters, given that these letters do not conflict with other interface
types. Therefore, you can input 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 creating 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
corresponds to the main interface.
