Performing a Basic Configuration
The following steps are for a basic interface configuration for the PA-E3. 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:
router# disable
router>
Step 1 At the privileged-level prompt, enter configuration mode and specify that the console
terminal is the source of the configuration subcommands:
router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#
Step 2 Specify the interface to configure:
• ForCisco 7100 series,Cisco 7200 series,or Cisco uBR7200 seriesrouters, specifythe
interface to configure by entering the subcommand interface serial followed by the
slot/port (port adapter slot number and interface port number). The example that
follows is for the interface of the port adapter in slot 3:
router(config)# interface serial 3/0
• For a VIP2, specify the interface to configure by entering the subcommand
interface serial, followed by the slot/port-adapter/port (interface processor slot
number, port adapter slot number, and interface port number). The example that
follows isfor the interface ofthe first portadapter on aVIP2 in interface processorslot
1:
router(config)# interface serial 1/0/0
• For a Catalyst RSM/VIP2, specify the interface to configure by entering the
subcommand interface serial, followed by the port-adapter/port (port adapter slot
number and interface port number). The example that follows is for the interface of
the first port adapter on a Catalyst RSM/VIP2:
router(config)# interface serial 0/0
