This chapter provides the information you need to prepare for first-time startup. Read it before you power up your system.
Preparing for first-time startup is highly recommended to take advantage of the full range of configurability available on Cisco protocol translators. Note that you are not required to plan your network before sitting at the console and using the setup command facility for the first time, but connecting to the console port is required. By separating the planning tasks from the configuration tasks, you can tailor the protocol translator to meet your needs and to fit within a consistent scheme.
This chapter describes the following tasks:
The values on these worksheets map to the configuration process of the setup command which is automatically invoked at first-time startup. You will specify global, or system-wide configuration information and information about the individual interface. You will use the values you have filled in on the Protocol Translator Configuration Worksheet. Blank
configuration worksheets have been provided in Appendix B for your convenience.
In the following descriptions of the parameters that you will determine, the factory default is marked with the Default: label.
The Protocol Translator Configuration Worksheet, if properly filled out, will contain all the values you need to enter at the the System Configuration Dialog of the setup command facility. Remember, the setup command facility is automatically invoked at first-time startup. You want all your preparations to be complete so that you can get your system up and running quickly and uneventfully.
The Protocol Translator Configuration Worksheet can assist you in gathering and maintaining information about your system. Three levels of information are listed on the Protocol Translator Configuration Worksheet:
System hardware information is not requested at first-time startup, but is useful to note on the Protocol Translator Configuration Worksheet to complete your records. Global and interface parameters, however, are requested at first-time startup.
In the following parameter descriptions, the action you need to take to fill in the worksheet is marked with the Action: label.
The Protocol Translator Configuration Worksheet is shown on the next page. Retrieve the blank Protocol Translator Configuration Worksheet provided in Appendix B before continuing. Use it as you proceed through the descriptions to record your information.
Protocol Translator Configuration Worksheet
This section contains information that helps you record the system hardware information in the "System Hardware Information" portion of Protocol Translator Configuration Worksheet. This information is not requested at first-time startup.
Cisco offers several protocol translators designed to accommodate a wide variety of needs. The system type is clearly marked on the front of your protocol translator. Customers can choose from single-board systems or card-based chassis configurations. The protocol translator models are available as follows:
Default: None
Action: Circle your system type from those listed on the Protocol
Translator Configuration Worksheet.
Each system has a serial number placed on the back or bottom panel. This information may be useful in tracking your physical inventory.
Default: None
Action: Note your system serial number on the worksheet.
The number of interfaces depends on the type of system you have and the number of interface cards you have installed. If you are installing a new system, it will be preconfigured at the factory; this means the number of interfaces are determined when you order the system. Check the back of your protocol translator to determine the installed interfaces.
The number of interfaces installed will affect the second part of the configuration process. It will determine the information you need to provide at first-time startup.
Default: None
Action: Note the number of interfaces on the Protocol Translator
Configuration Worksheet.
This section contains information about each global parameter that is configurable through the setup command facility. Use this information to complete the "Global Parameters" portion of the Protocol Translator Configuration Worksheet and at first-time startup.
The host name is the name of the host computer of the protocol
translator. The name you specify is used in the system prompts and can contain 1 to 80 uppercase and lowercase alphanumeric characters. The host name is case sensitive.
Try to use names that will help you identify the location of the protocl translator, or to whom it is providing routing services. If you will be naming more than one host within your network, try to devise a consistent naming scheme so that host identification is easy.
Default: PT
Action: Note the host name in the Protocol Translator Configuration Worksheet the way you want it to appear in the system prompts.
Your system has two levels of security: user and privileged. The commands available at the user level are a subset of those available at the privileged level. Because many of the privileged commands are used to set operating parameters, these should be password-protected to prevent unauthorized use.
The enable password allows a user access to the privileged command level. There is no default enable password. However, the enable password you set during first-time startup will display as the default the next time you run the setup command facility.
An enable password can contain 1 to 80 uppercase and lowercase alphanumeric characters; a number cannot be the first character. Spaces are also valid password characters; for example, "two words" is a valid password.
For more information about the enable password, refer to Chapter 4 of the Protocol Translator Configuration and Reference publication.
Default: None
Action: Note the enable password on the Protocol Translator Configuration Worksheet.
In addition to the enable password, each virtual terminal line can also have an individual password. Virtual terminals require a password. If you do not set a password, the system will respond to attempted connections by displaying an error message and closing the connection. (Virtual terminals are used when you access the protocol translator remotely via the network.)
A virtual terminal password can contain from 1 to 80 uppercase and lowercase alphanumeric characters; a number cannot be the first character. Spaces are also valid password characters; for example, "two words" is a valid password. The virtual terminal password is case sensitive. There is no default virtual terminal password. However, the virtual terminal password you set during first-time startup, will display as the default the next time you run the setup command facility.
If desired, you can allow line connections without a password. Refer to the Chapter 4 of the Protocol Translator Configuration and Reference publication for more information.
Default: None
Action: Note the virtual terminal password on the Protocol Translator Configuration Worksheet.
The Simple Network Management Protocol (SNMP) is the most widely supported open standard for network management. It provides a means to access and set configuration and run-time parameters of routers and protocol translators. SNMP defines a set of functions that may be used to monitor and control network elements.
SNMP is configured on a global basis only; it cannot be specified for
individual interfaces.
Default: No
Action: Circle Yes on the Protocol Translator Configuration Worksheet if you want to configure SNMP on a system-wide basis. At first-time startup this value configures read-only SNMP with a blank password. If you do not want to run SNMP on your system, circle No.
Cisco supports the Network Computing Device, Inc. XRemote feature on all communication servers and protocol translators. When fonts used by X applications are not included in ROM on the NCD terminal, one or more font servers must be identified from which the protocol translator and the NCD terminal can obtain fonts from other than ROM. You can identify as many XRemote font servers as you need; it is unlikely that you will ever reach the maximum number that the software allows you to identify.
Default: No
Action: Circle Yes on the Protocol Translator Configuration Worksheet if you want to configure one or more XRemote font servers. If you do not want to configure XRemote font servers on your system, circle No.
If you will be using one or more XRemote font servers, you must also provide an IP address for each XRemote font server. This step is equivalent to specifying the IP address of a font server using the xremote tftp host configuration command. However, you cannot specify an XRemote host name through the setup command facility because the name service facility is not yet running.
Indicate an IP addresses on the Protocol Translator Configuration Worksheet for XRemote font server as follows:
| First Class | First Byte | Network Bits | Host Bits |
|---|---|---|---|
| A | 1-126 | 8 | 24 |
| B | 128-191 | 16 | 16 |
| C | 192-223 | 24 | 8 |
For more information about XRemote configuration and management information, refer to Chapter 14 of the Protocol Translator Configuration and Reference publication.
This section contains information about each interface parameter that is configurable through the setup command facility for the installed network. Use this information to complete the "Interface Parameters" portion of the Protocol Translator Configuration Worksheet and at first-time startup.
The setup command facility automatically presents each installed interface for you to configure. The interfaces are presented in the same order as they are installed in the chassis. For example, if you had one Ethernet interfaces and one serial interface, you would be prompted to configure interface Ethernet0 then Serial0.
The number of interfaces indicates how many columns you will need to provide information in.
Default: The default is based on the interfaces installed in the chassis.
Action: Write each interface name across the top of the Protocol Translator Configuration Worksheet in the row labeled "Interface Name."
You must also provide the IP address and subnet mask bits for the installed interfaces. Indicate values on the Protocol Translator Configuration Worksheet as follows:
DEC's Local Area Transport (LAT) protocol is the protocol used most often to connect to DEC hosts. LAT is a DEC-proprietary protocol. Cisco uses LAT technology licensed from DEC.
The LAT protocol allows a user at one site to establish a connection to a host then passes the user's keystrokes to the host. A user can establish a LAT connection through the protocol translator to a DEC host, simply by entering the host name.
LAT cannot be routed because DEC's LAT protocol includes its own transport protocol (Layer 4 of the OSI reference model) which runs directly over Ethernet (Layer 2 of the OSI reference model) rather than a standard routing layer. LAT must be bridged to pass between different network segments. The protocol translator provides the option of transporting LAT in protocol translation mode. With Cisco protocol translators, you can establish a configuration so that the protocol translator software will translate LAT to Telnet or X.25 for transmission over a WAN which can be translated back to LAT on the other end of the connection. You can configure this WAN to LAT translation to be transparent to the user. This configuration also avoids LAT time-out problems which are common in WAN bridged LAT. For more information about Cisco's implementation of LAT refer to the chapter entitled "LAT Configuration and Management" in the Protocol Translator Configuration and Reference publication.
Default: Yes
Action: Write Yes on the Protocol Translator Configuration Worksheet if you plan to use LAT on the interface. Write No if you do not want to use LAT on the interface. Repeat this for each of the installed interfaces.
Attach an RS-232 ASCII terminal to the system console port located at the rear of the protocl translator. Configure the terminal to operate at:
If you have filled out the worksheet and have connected to the console port, you are now ready for first-time startup. Turn to Chapter 3, "First-Time Startup."
