Chapter 3 ROM Monitor Commands
T
his chapter describes the ROM Monitor commands that are
available in Monitor Mode. Access these commands through a
terminal connected to the service port (located on the front of the hub
chassis).
The ROM Monitor commands allow you to set a subset of the
configuration (EEPROM) parameters. Some of these parameters, like
the unit's IP address, are required for booting the Remote Annex;
some parameters, like the broadcast address, are required if the
network configuration differs from the supplied defaults. Table 3-1
lists the ROM Monitor commands.
Other parameters, although not required, are recommended for the
Remote Annex's initial boot. Setting these parameters, rather than
using the assigned defaults, minimizes errors during the initial boot.
For example, setting the parameter that defines the preferred load
host enables the Remote Annex to load by requesting assistance from
a specific host, rather than by broadcasting that request to all hosts
on the subnet.
After the Remote Annex has booted, you can define the same
parameters you defined using the ROM Monitor, by using the na
utility, the local CLI admin command, or SNMP. The Remote Annex
Administrator's Guide for UNIX describes the na utility in detail. See
Chapter 4 for information on power-up and boot procedures.
ROM Monitor commands generally provide data about a subset of
current configuration (EEPROM) parameters. When appropriate,
they also display a prompt that allows the operator to change those
parameters.
