ROM Monitor Commands
This chapterdescribesthe ROM Monitorcommandsthatare 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 theseparameters, like the
unit’sIP address, are required for booting the Model5399Remote Access
Concentrator; 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 Access Concentrator’s initial boot. Setting these parameters,
rather than usingthe assigneddefaults, minimizeserrors during the initial
boot. For example, setting the parameter that defines the preferred load
host enables the Remote Access Concentrator to load by requesting
assistance from a specific host, rather than by broadcasting that request
to all hosts on the subnet.
After the Remote Access Concentrator has booted, you can define the
same parameters you defined using the ROM Monitor, by using the
host-based 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
forinformation on power-up andboot procedures.
ROM Monitor commands generally providedataabout a subsetofcurrent
configuration (EEPROM) parameters. When appropriate, they also
display a prompt that allows the operator to change those parameters.
