This chapter describes the initial configuration for Cisco DistributedDirector System Software for the Cisco DistributedDirector 2500 Series, and contains the following sections:
This chapter provides just enough information to get the Director up and running. Detailed software configuration information is available in other chapters in this guide.
Each time you power on the Director, it goes through the following boot sequence:
The first time you boot your Director, you will need to configure the Director interfaces and then save the configuration to a file in NVRAM.
You can configure the Director using one of the following procedures, which are described in this section:
 | Time Saver Acquire the correct network addresses from your system administrator or consult your network plan to determine the correct addresses before you begin to configure the Director. |
Proceed with the procedure that best fits the needs of your network configuration and Cisco IOS software experience level. If you will be using the configuration mode to configure the Director, and you would like a quick review of the Cisco IOS software, refer to the section "Cisco IOS Software Basics" later in this chapter. Otherwise, proceed with the next section "Using the System Configuration Dialog."
If your Director does not have a configuration (setup) file the Cisco DistributedDirector System Software will automatically start the setup command facility. An interactive dialog called the System Configuration Dialog appears on the console screen. This dialog helps you navigate through the configuration process by prompting you for the configuration information necessary for the Director to operate.
Many prompts in the System Configuration Dialog include default answers, which are included in square brackets following the question. To accept a default answer, press Return; otherwise, enter your response.
This section gives an example configuration using the System Configuration Dialog. When you are configuring your Director, respond as appropriate for your network.
At any time during the System Configuration Dialog, you can request help by typing a question mark (?) at a prompt.
Before proceeding with the System Configuration Dialog, obtain from your system administrator the node addresses and the number of bits in the subnet field (if applicable) of the Director port. For more information about IP addresses and subnets, refer to the Internetworking Technology Overview publication.
Take the following steps to configure the Director using the System Configuration Dialog:
Step 1 Connect a console terminal to the console port on the rear panel of your Director, and then power ON the Director. (For more information, refer to the section "Connecting the Console Terminal and Modem" in the chapter "Installing the Cisco DistributedDirector 2500 Series".)
Step 2 After about 30 seconds, information similar to the following is displayed on the console screen:
Step 3 Press Return or enter yes to begin the configuration process.
Step 4 When the System Configuration Dialog asks whether you want to view the current interface summary, press Return or enter yes:
Step 5 Configure the global parameters. A typical prompt follows:
Next, you are prompted to enter an enable secret password. There are two types of privileged-level passwords:
The enable password is used when the enable secret password does not exist.
For maximum security, be sure the passwords are different. If you enter the same password for both, the Director will accept your entry, but will display a warning message indicating that you should enter a different password.
Step 6 Enter an enable secret password:
pail
Step 7 Enter the enable and virtual terminal passwords:
shovel
vterm1
Step 8 Press Return to accept Simple Network Management Protocol (SNMP) management, or enter no to refuse it:
no
Step 9 Press Return or enter yes to configure the DD for IP:
15
The Ethernet interface is configured to allow connection to a LAN. To configure the interface parameters, you need to know your Ethernet interface network addresses.
Take the following steps to configure an Ethernet interface to allow communication over a LAN:
Step 1 Press Return or enter yes to configure the LAN interface:
Step 2 Press Return or enter yes to configure the IP protocol:
172.16.72.1
8
The Token Ring interface is configured to allow connection to a LAN. To configure the interface parameters, you need to know your Token Ring interface network addresses.
Take the following steps to configure a Token Ring interface to allow communication over a LAN:
Step 1 Press Return or enter yes to configure the LAN interface:
Step 2 Press Return or enter yes to configure the IP protocol:
172.16.72.1
8
You can configure the Director manually if you prefer not to use the prompt-driven System Configuration Dialog. Take the following steps to configure the Director manually:
Step 1 Connect a console terminal and then power ON the Director.
Step 2 When you are prompted to enter the initial dialog, enter no to go into the normal operating mode of the Director:
no
Step 3 After a few seconds you will see the user EXEC prompt (DD>). Enter the enable command to enter privileged EXEC mode. You can only make configuration changes in privileged EXEC mode:
enable
The prompt changes to the privileged EXEC prompt:
Step 4 Enter the configure terminal command at the privileged EXEC prompt to enter configuration mode:
configure terminal
You can now enter any changes you want to the configuration. You will probably want to perform the following tasks:
(a) Assign a host name for the Director using the hostname command. (The default assigned name is DD.)
(b) Enter an enable secret password using the enable password command.
(c) Assign addresses to the interfaces using the protocol address command.
(d) Specify which protocols to support on the interfaces.
Refer to the rest of this installation and configuration guide for more information about the commands you can use to configure the Director.
Step 5 When you are finished configuring the Director, enter the exit command until you return to the privileged EXEC prompt. (If you have not assigned a new host name, the prompt will be DD#.)
Step 6 To save the configuration changes to NVRAM, enter the copy running-config startup-config command at the privileged EXEC prompt.
copy running-config startup-config
The Director is now configured and will boot with the configuration you entered.
This section provides you with some basic information about the Cisco IOS software and includes the following sections:
The Cisco IOS software provides access to several different command modes. Each command mode provides a different group of related commands.
For security purposes, the Cisco IOS software provides two levels of access to commands: user and privileged. The unprivileged user mode is called user EXEC mode. The privileged mode is called privileged EXEC mode and requires a password. The commands available in user EXEC mode are a subset of the commands available in privileged EXEC mode.
Table 4-1 describes some of the most commonly used modes, how to enter the modes, and the resulting prompts. The prompt helps you identify which mode you are in and, therefore, which commands are available to you.
| Mode of Operation | Usage | Access Method | Prompt | Exit Method |
|---|---|---|---|---|
| User EXEC | User EXEC commands allow you to connect to remote devices, change terminal settings on a temporary basis, perform basic tests, and list system information. The EXEC commands available at the user level are a subset of those available at the privileged level. | Log in. | DD>
| Use the logout command. |
| Privileged EXEC | Privileged EXEC commands set operating parameters. The privileged command set includes those commands contained in user EXEC mode, and also the configure command through which you can access the remaining command modes. Privileged EXEC mode also includes high-level testing commands, such as debug. | From user EXEC mode, use the enable EXEC command.
| DD#
| To exit back to user EXEC mode, use the disable command.
To enter global configuration mode, use the configure privileged EXEC command. |
| Global configuration | Global configuration commands apply to features that affect the system as a whole. | From privileged EXEC mode, use the configure privileged EXEC command. | DD(config)#
| To exit to privileged EXEC mode, use the exit or end command or press Ctrl-Z.
To enter interface configuration mode, enter an interface configuration command. |
| Interface configuration | Interface configuration commands modify the operation of an interface such as an Ethernet port. Many features are enabled on a per-interface basis. Interface configuration commands always follow an interface global configuration command, which defines the interface type. | From global configuration mode, enter by specifying an interface with an interface type number command. For example, enter the interface ethernet 0 command to configure the Ethernet 0 interface. | DD(config-if)#
| To exit to global configuration mode, use the exit command.
To exit to privileged EXEC mode, use the exit command or press Ctrl-Z. |
| Key chain configuration | From key chain configuration mode, you can manage authentication keys. To enter this configuration mode, you must first enable the DRP server agent. | From global configuration mode, use the key chain command. | DD(config- keychain)#
| To exit to global configuration mode, use the exit command. |
| Key chain key configuration | Once you define a key chain, use the key chain key configuration mode to configure the keys on the key chain. | From key chain configuration mode, use the key command. | DD(config- keychain-key)#
| To exit to key chain configuration mode, use the exit command. |
| ROM monitor | ROM monitor commands are used to perform low-level diagnostics. You can also use the ROM monitor commands to recover from a system failure and stop the boot process in a specific operating environment.1 | From privileged EXEC mode, use the reload EXEC command. Press Break during the first 60 seconds while the system is booting. | >
| To exit to user EXEC mode, type continue. |
Almost every configuration command also has a no form. In general, use the no form to disable a feature or function. Use the command without the keyword no to reenable a disabled feature or to enable a feature that is disabled by default. For example, the Director cache enabled by default. To disable the cache, enter the no ip director cache command and enter ip director cache to reenable it. The "Command Summary and Reference" chapter provides the complete syntax for Director configuration commands and describes what the no form of a command does. Additional system commands are documented in the Cisco IOS software command references.
In any command mode, you can get a list of available commands by entering a question mark (?).
DD> ?
To obtain a list of commands that begin with a particular character sequence, type in those characters followed immediately by the question mark (?). Do not include a space. This form of help is called word help, because it completes a word for you.
DD# co?
configure connect copy
To list keywords or arguments, enter a question mark in place of a keyword or argument. Include a space before the question mark. This form of help is called command syntax help, because it reminds you which keywords or arguments are applicable based on the command, keywords, and arguments you have already entered.
DD# configure ?
memory Configure from NV memory
network Configure from a TFTP network host
terminal Configure from the terminal
<cr>
You can also abbreviate commands and keywords by entering just enough characters to make the command unique from other commands. For example, you can abbreviate the show command to sh.
You must save changes made to the Director configuration to memory, otherwise they will be lost if there is a system reload or power outage. There are two types of configuration files: the running (current operating) configuration and the startup configuration. The running configuration is stored in RAM; the startup configuration is stored in NVRAM.
To display the current running configuration, enter the show running-config command. Enter the copy running-config startup-config command to save the current running configuration to the startup configuration file in NVRAM.
DD>enableDD#copy running-config startup-config
To display the startup configuration, enter the show startup-config command. Enter the copy startup-config running-config command to write the startup configuration to the running configuration:
DD>enableDD#copy startup-config running-config
To erase both configuration files (and start over), enter the write erase and reload commands:
DD>enableDD#write eraseDD#reload
 | Caution This command sequence will erase the entire Director configuration in RAM and NVRAM and reload the Director. |
When you have configured an interface (for example, and Ethernet interface), use the show interfaces command to check the network interface statistics. Options to the show interface command include the type of interface (for example, Token Ring, Ethernet, and so on), and the unit number of the interface. The following example shows the output of show interfaces ethernet 0:
DD> show interfaces ethernet 0
Ethernet 0 is up, line protocol is up

The field underruns in the output of the show interface command may be nonzero in approximately one of 250,000 packets.
To display the current internal status of a network processor module, use the show controller command with the interface type and unit number options. The following is the output of the show controller ethernet 0 command:

After you have installed and configured the Director, you can use the following commands in user EXEC mode to verify network connectivity:
For troubleshooting information, refer to the Cisco IOS System Error Messages and Debug Command Reference publications. You can also access "Technical Assistance" at the World Wide Web URL http://www.cisco.com (Cisco Connection Online) for a list of frequently asked questions and technical tips.
You can enter multiple boot commands in the configuration in NVRAM to provide a backup method for loading the Cisco DistributedDirector image onto the Director. The Director boots using the first boot command that succeeds. If you enter multiple boot commands, the Director executes them in the order they are entered. There are two ways to load the Cisco DistributedDirector image: from Flash memory or from a TFTP server on the network.
DD>enablePassword:enablepasswordDD#configure terminalDD (config)#boot system flashfilenameDD (config)#Ctrl-ZDD#copy running-config startup-configBuilding configuration ... [OK] DD#exitDD>
DD>enablePassword:enablepasswordDD#configure terminalDD (config)#boot system tftpfilename ipaddressDD (config)#Ctrl-ZDD#copy running-config startup-configBuilding configuration ... [OK] DD#exitDD>
For more information about Director software configuration refer to the chapter "Command Summary and Reference."
In addition, the Cisco IOS configuration guide and command reference publications are available on the Documentation CD-ROM, Cisco's online library of product information.
