Boot Options

This document covers the boot options available at the boot monitor prompt (>). You need to use boot options only for maintenance or diagnostic operations or for software upgrades.

Boot options let you boot your router using these methods:

Additional options available at the > prompt let you run diagnostics, display configuration information, load configuration memory from a host on the network or through the service port, clear configuration in SRAM, and load router code on configuration files through the service port or the console port.

This document contains the following topics.

Before You Begin

 Before booting your router, note the following:

Boot Options

 Table 1 lists the boot options available for your router. Detailed descriptions of the boot options and boot option prompts follow the table.

Accessing the Boot Options

1. Begin a load procedure by powering on your router or by entering reload at the * prompt.

2. Press Ctrl c during the load procedure to display the > prompt.

3. Press Enter to display the boot options described in Table 1.

The following sections explain the options in detail.

Table 1 Boot Options

Option Description
B (Boot) Boots automatically using the configuration stored in TFTP or in the IBD.

BC (Boot to Config-only Mode) Use this option to boot your router manually by responding to console queries and then enter Config-only mode.

BM (Boot using console queries) Use this option to boot over the IBD, over the LAN interface, or over the WAN interface manually. You can also use this option to boot from a load image file on a TFTP host server.

BN (Boot, but do not run) Used by field personnel for debugging.

BP (Boot using BOOTP) Use this option to boot using the BOOTP Protocol.

DIAG (Execute resident extended diagnostic program) Starts internal tests. When internal tests are complete, you can run the System Diagnostics, the WAN/LAN Wrap tests, or Diagnostic Utilities. You can exit and reboot at any time.

UB (Display Boot Configuration) Displays the static RAM TFTP bootstrap configuration.

UC (Display Hardware Configuration) Displays the information on the hardware configuration including device types, baud rate, memory sizes, Base MAC address, part numbers, serial numbers, and revision levels.

UG (Go execute at address in RAM) This option is used by field service personnel.

LC (Load Configuration Memory) Loads configuration memory from a host on the network.

CC (Clear Configuration Memory) Clears the configuration in SRAM.

ZB (ZModem Boot) Loads router code through the service port.

ZC (ZModem configuration memory load) Loads configuration memory through the service port.

Boot Option Prompts

Table 2 describes the prompts that appear when you boot your router. These prompts vary depending on your hardware configuration and the software loaded on the router.

Table 2 Boot Option Prompts

Prompt Description 
Device type
 The device type over which to boot your router, either the IBD, the Token Ring or Ethernet device, or the WAN device.

LAN port or WAN port
 Asks which port, if more than one of the selected type is available. Selection is based on the numbering on the router.

IBD loadname
 The IBD loadname can include up to 79 characters, digits, and symbols and is case-sensitive. For initial installations, enter the loadname noted in the Release Notes. If you enter an incorrect or non-existent loadname, the system issues the message: No such load and returns you to the IBD Loadname prompt.

Interface IP address
 The IP address of the router's interface over which you are booting. 

IP mask
 The IP mask of the IP address in hexadecimal. All bits that are part of the network and subnet should be 1.

Boot from host
 IP address of the host from which you are booting.

Via gateway
 If the host from which you are booting is on another (sub)network, there is an intermediate router. Enter the IP address of the intermediate router.

Load image name
 For initial installations, enter the load image name noted in the Release Notes.

Boot file name
 Filename of where the load image file resides on the host server. Filename is dependent upon TFTP server.

Ethernet Prompts 
Connector type (AUI/RJ45)
If router has two Ethernet ports you are prompted for which one (1 or 2). Enter one of the following to specify the cable type connected to this port:

AUI Thick/AUI (10Base5)

RJ45 Unshielded Twisted Pair (10BaseT)

AUTOCONFIG Automatically senses the cable type

Token Ring Prompts 
Speed (4/16) Mb
 If router has two Token Ring ports you are prompted for which one (1 or 2).
Enter 4 or 16 to represent the Token Ring media transfer rate in Mbps (megabits per second).

Note: The value you enter must match the speed of the ring.

Media (UTP/STP)
 Enter one of the following to specify the cable type connected to this device:

 UTP Unshielded Twisted Pair

STP Shielded Twisted Pair

WAN Prompts 
WAN port
 WAN port over which you are booting your router. Enter 1, 2, 3, or 4.

Timeout (secs)
 How long, in seconds, the interface tries to boot over the network. The timeout must be greater than 5.

Clock source (INT/EXT)
 To connect to a

Internal clock speed
 This prompt appears only if you enter INT as the Clock Source. The range is 1<1536000 < 10000000 bps.

Cable type (X21/OTHER)
 Enter X21 to connect an X.21 cable to this port. Enter OTHER to connect an RS-232, V.35, or V.36 cable to the port.

The following sections explain each of the boot options for your router.

B (Boot)

Boots the router automatically using the configuration stored in configuration memory. This option causes the router to boot from the IBD unless the configuration is stored on a TFTP host.

BC (Boot to Config-only Mode)

Boots the router and immediately enters Config-only mode.

1. Enter bc at the > prompt.

2. Respond to the prompts described in Table 2.

When the software has finished loading, it displays the Config (only)> prompt.

BM (Boot using console queries)

Boots the router using console queries. You can use this option to boot from the IBD or over the LAN or WAN devices. You can also use this option to boot from a load image file on a TFTP host server.

Another OpenROUTE Networks router can act as a TFTP host server.

1. Enter bm at the > prompt to begin booting using console queries.

2. Respond to the prompts described in Table 2.

When the software has finished loading, it displays the * prompt.

BN (Boot, but do not run)

This option should be used only by field service personnel.

BP (Boot using BOOTP)

BOOTP boots your router over the LAN port using the Bootstrap Protocol.

1. Enter bp at the > prompt.

2. Respond to the prompts described in Table 2.

A BOOTP boot is successful when the terminal displays the * prompt.

Unsuccessful BOOTP

A BOOTP boot fails if the server is down, if the server cannot find the file you specified, or if TFTP fails. If BOOTP is unsuccessful, the terminal displays the following message:

Manual BOOTP failed - enter "@" at prompt to BOOTP again
Enter @ to retry BOOTP. If the retry fails, use another method to boot your router.

DIAG (Execute resident extended diagnostic program)

Initiates internal self-test. When internal self-test is complete, you can select any of the diagnostic utilities provided. To run some of the diagnostics you need wrap plugs, which are contained in your router's Accessories Kit.

1. Enter diag at the > prompt to execute the internal self-test.

2. When prompted, press Space to display the Diagnostic Main Menu. 

1) System Diagnostics (Internal Tests)
2) System Extended Diagnostics (Internal and External Tests)
3) WAN/LAN Wrap Menu
4) Diagnostic Utilities

x) Exit (and Reboot)

Enter the number of your choice:
3. Enter the number that corresponds to the test you want to run. For some options, additional menus prompt you for more information.

Note: If you run a test that requires wrap plugs, you receive the following message:

You have selected a test that requires external wrap 
plugs to be present.  Remove the cable(s) from the
network, and attach the appropriate wrap plug(s).

UB (Display Boot Configuration)

Displays the static RAM TFTP bootstrap configuration including

If you have created dump records, UB also displays the dump file name and IP address of the host on which the dump files will be placed and the IP address of the intermediate gateway, if applicable.
