Cisco Systems PA-4R manual Using the Exec Command Interpreter

VIP2 and the 4R Port Adapter

For example, the addresses for the 4R interface ports on the first port adapter on a VIP2 (see ) are 3/0/0 through 3/0/3 (chassis slot 3, port adapter slot 0, and interface ports 0 through 3). If the 4R port adapter were installed in port adapter slot 1, the interface addresses would be 3/1/0 through 3/1/3.

Note If you remove the 4R-equipped VIP2 (shown in ) from chassis slot 3 and install it in slot 2, the addresses of those same ports become 2/0/0 through 2/0/3.

You can identify interface ports by physically checking the slot/port adapter/interface port location on the back of the router or by using software commands to display information about a specific interface or all interfaces in the router.

Using the EXEC Command Interpreter

		You can modify the startup configuration for Cisco 7500 series routers through the software command
		interpreter called EXEC. To configure the interfaces for interface processors, you can use either one of
		the setup or configure EXEC commands.
		The setup command facility can be used after first time startup to make basic changes at any time. The
		changes you make will affect only the changed elements’ current memory values that are stored in
		nonvolatile memory.
		The configure privileged EXEC command enables you to perform advanced configurations such as
		specifying interfaces. The EXEC interprets the commands you enter and carries out the corresponding
		operations. You can list available EXEC commands by entering a question mark (?). You also can enter
		a question mark to obtain more information about commands. For example, enter terminal ? to obtain
		a list of terminal commands or show ? to obtain a list of show commands.
		Before you use the setup or the configure command, you must have privileged access to the EXEC
		command interpreter. The system prompt for the privileged level ends with a pound sign (#) instead of
		an angle bracket (>). The EXEC enable command allows access to the privileged level, prompting for a
		password if one has been set with the enable-passwordconfiguration command.
		Follow these steps to enter the privileged level of the EXEC.
	Step 1	At the EXEC prompt for a router, enter the enable command:
