CHAPTER 3

CONFIGURING

The ATX does not require any additional conﬁguration to operate

as a standard transparent bridge. However, if you want it to

communicate with an SNMP manager, you have to assign an IP

address to the port through which you will be communicating with

the SNMP manager. If you want the ATX to perform IP, IPX

routing, or AppleTalk, you need to do some conﬁguring. If you are

using a Token Ring module (3T02-04 or 3T01-04) you may need to

make some conﬁguration changes as well, refer to the Token Ring

Switch Module User Guide.

You can conﬁgure your ATX using the LCM, which allows you to

monitor, manage, and conﬁgure your ATX through an out-of-band

RS-232 connection. You can also use any SNMP-based network

management station.

Conﬁguration parameters are stored in an SNMP standard

Management Information Base (MIB), which includes Standard

Microsystems' enterprise extensions (variables speciﬁc to the ATX).

All ATX MIB variables are listed and described in the ATX MIB

Reference Guide.

This manual provides LCM commands you can use to conﬁgure

your ATX. If you are using a tool other than LCM, refer to its

accompanying documentation.

3.1 CONFIGURING BRIDGING

A bridge is a device that makes it possible to link two or more

networks together. Figure 3-1 shows a typical bridging application

in which three bridges are used to connect three local area

networks (LANs) to a ﬁber optic “backbone” network. Bridges

make interconnected network segments look and function like a

single network while reducing intersegment trafﬁc.
