Cable Installation and Interface Configuration 7-7

Configuring Interfaces

Following is an example of a basic conﬁguration procedure:

Step 1 At the privileged-level prompt, enter conﬁguration mode and specify that the console

terminal will be the source of the conﬁguration subcommands, as follows:

Router# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#

Step 2 For the Cisco 7200 series and CiscouBR7200 series routers, at the prompt specify the

ﬁrst interface to conﬁgure by entering the subcommand interface, followed by thetype

(hssi) and slot/interface (port adapter slot number and interface number). The example

that follows is for the ﬁrst interface of the port adapter in slot 2.

Router(config)# interface hssi 2/0

Note For the Cisco 7206 and Cisco 7206VXR router shelves, the interface speciﬁed in

the above example would include a shelf number. For example, the command interface

hssi5/2/0 would specify the ﬁrst HSSI interface of the port adapter in slot 2 of Cisco 7206

or Cisco 7206VXR router shelf5.

For the VIP2, at the prompt specify the ﬁrst interface to conﬁgure by entering the

subcommand interface, followed by the type(hssi) and slot/port adapter/interface

(interfaceprocessor slot number). The example that follows is for the ﬁrst interface of the

ﬁrst port adapter on a VIP2 in interface processor slot 1:

Router(config)# interface hssi 1/0/0

For the Catalyst RSM/VIP2, at the prompt specify the ﬁrst interface to conﬁgure by

entering the subcommand interface, followed by thetype (hssi) and port

adapter/interface. The example that follows is for the ﬁrst interface of the ﬁrst port

adapter on a Catalyst RSM/VIP2:

Router(config)# interface hssi 0/0

Step 3 If IP routing is enabled on the system, you can assign an IP address and subnet mask to

the interface with the ip address conﬁguration subcommand, as in the following

example:

Router(config-int)# ip address 1.1.1.10 255.255.255.0

Step 4 Add any additional conﬁguration subcommands required to enable routing protocols and

set the interface characteristics.

Step 5 Change the shutdown state to up and enable the interface as follows:

Router(config-int)# no shutdown

Step 6 Conﬁgure additional interfaces as required.

Step 7 When you have included all of the conﬁguration subcommands to complete the

conﬁguration, press Ctrl-Z to exit conﬁguration mode.

Step 8 Write the new conﬁguration to nonvolatile memory as follows:

Router# copy running-config startup-config

[OK]

Router#
