Interface Commands IR-111

Examples

The following example conﬁgures serial interface 0 with PPP encapsulation:

interface serial 0

encapsulation ppp

The following example enables loopback mode and assigns an IP network address and network mask

to the interface. The loopback interface established here will always appear to be up:

interface loopback 0

ip address 131.108.1.1 255.255.255.0

The following example for the Cisco 7500 series router shows the interface conﬁguration command

for Ethernet port 4 on the EIP that is installed in (or recently removed from) slot 2:

interface ethernet 2/4

The following example begins conﬁguration on the Token Ring interface processor in slot 1 on

port 0 of a Cisco 7500 series routers:

interface tokenring 1/0

The following example shows how a partially meshed Frame Relay network can be conﬁgured. In

this example, subinterface serial 0.1 is conﬁgured as a multipoint subinterface with three Frame

Relay PVCs associated, and subinterface serial 0.2 is conﬁgured as a point-to-point subinterface.

interface serial 0

encapsulation frame-relay

interface serial 0.1 multipoint

ip address 131.108.10.1 255.255.255.0

frame-relay interface-dlci 42 broadcast

frame-relay interface-dlci 53 broadcast

interface serial 0.2 point-to-point

ip address 131.108.11.1 255.255.0

frame-relay interface-dlci 59 broadcast

The following example conﬁgures circuit 0 of a T1 link for Point-to-Point Protocol (PPP)

encapsulation:

controller t1 4/1

circuit 0 1

interface serial 4/1:0

ip address 131.108.13.1 255.255.255.0

encapsulation ppp

The following example conﬁgures LAN Extender interface 0:

interface lex 0

tokenring Token Ring interface.

tunnel Tunnel interface; a virtual interface. The number is the number of the

tunnel interface that you want to create or conﬁgure. There is no limit on

the number of tunnel interfaces you can create.
