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:

•For Cisco 7100 series, Cisco 7200 series, or Cisco uBR7200 series routers, specify the 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 is for the interface of the ﬁrst port adapter on a VIP2 in interface processor slot 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
