Configuring Interfaces

Conﬁguring Interfaces

Use the following steps to perform a basic conﬁguration. Press the Return key after each step unless

otherwise noted. At any time you can exit the privileged level and return to the user level by entering

disable at the prompt as follows:

Router# disable

Router>

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, Cisco uBR7200 series, or Cisco 7100 series routers, at the

prompt specify the ﬁrst interface to conﬁgure by entering the subcommand interface,

followed by the type (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 hssi 5/2/0 would specify the ﬁrst HSSI interface of the port adapter in slot 2 of

Cisco 7206 or Cisco 7206VXR router shelf 5.

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

(interface processor 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 the type (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 10.10.10.10 10.255.255.255

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.
