1.3 ABOUT IRM2 LOCAL MANAGEMENT
The IRM2/LM provides unique management and control capabilities for
the IRM2 module. You can access Local Management either through a
VT™ 200 or 300 series terminal, or terminals running emulation
programs for these series terminals, or through a Hayes compatible
modem.
With IRM2 Local Management, you have the tools to manage the IRM2
and its attached segments. For example, you can enable and disable ports
and set device parameters such as IP address, SubNet Mask, Default
Gateway, current date and time, modem baud rate, statistical counters,
refresh time, and enable or disable factory default settings.
You can also use Local Management to view a full array of statistics to the
port level, including the number of:
bytes received runt packets
packets no resource errors
received collisions misaligned packets
transmit collisions CRC errors
OOW collisions giant packets

INTRODUCTION
Since the IRM2 is an SNMP compliant device, you can also set
community names for the devices attached to your IRM2. These
community names serve four purposes:
• They provide a security. The IRM2 authenticates any SNMP request,
and only responds to those requests that have a community name
contained in the IRM2 community name table.
• They allow you to set which network management workstations
receive traps from the IRM2.
• They allow you to control Read, Read/Write, and Superuser access to
your device.
• They allow you to set Local Management passwords.

CHAPTER 2
GETTING STARTED
This chapter lists procedures for accessing IRM2 Local Management for
the IRM2. Information is provided on required terminal and cable
configurations for connecting to the IRM2’s Console port. Information is
also provided on accessing Local Management through a modem.
2.1 LOCAL MANAGEMENT FROM A TERMINAL
To access Local Management for the IRM2, you must attach a VT 200 or
300 series terminal, or terminals running emulation programs for these
series to the 9 pin port labeled CONSOLE on the IRM2.
2.1.1 Terminal Configurations
Use the following terminal configurations requirement to set up for the
local management CONSOLE port. When using a Digital Equipment
F3
Corporation (DEC™) VT 200 or 300 series terminal, press
the Setup Directory. When using a terminal emulator, refer to your
equipment user manual for setup procedures.
