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 Cisco uBR7200 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 ofthe 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 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#
