4 SNMP Installation
This section describes how to configure and use SNMP (simple network management
protocol) on the wireless link. The wireless bridge includes an SNMP agent that collects
valuable statistical and configuration information about the network interface card inside your
wireless link. Network administrators analyze this information to keep their networks
operating at peak efficiency.
The SNMP agent maintains a database of statistical and configuration information in RAM. It
obtains this information directly from the wireless bridge during operation. With this true
SNMP agent, any SNMP manager (e.g., Hewlett Packard’s Openview, Sun Microsystem’s
SunNet Manager) can directly monitor the LAN side of the wireless bridge.
If you purchased the SNMP upgrade package, you can use the SNMP agent with IPX and
TCP/IP networks. Although the SNMP agent does not require you to load a particular
operating system or protocol stack, an IP address must be available if it is to communicate
with SNMP stations using TCP/IP protocol. You can configure the SNMP at any time.
You need a monitor and keyboard to configure the SNMP agent in the wireless bridge. An
editor is included with the bridge to allow you to edit a file called pcagent.cfg. The agent is
configured when you use the editor to edit this file. The procedure for using this editor is:
1. From the main service monitoring screen that shows the bar graphs, press the
X key.
The system exits the bridge’s normal operating mode and displays a DOS-like prompt.
2. At this prompt, type
CLS and then press <Enter> to clear the screen.
3. Type
E pcagent.cfg and press <Enter>.
4. Edit the displayed fields or accept the defaults. Refer to Table 1 for the fields and their
default values.
5. Hold down the
<ALT> key and press the X key to exit and save the file.
6. Hold down the
<CTRL> and <ALT> keys, and press the <DELETE> key to reboot the system
and return it to the normal operating mode, or power off and on the system again.

• * smcDosWsIpAdr is the IP address string in the configuration file. It is assigned a value
in the form X.X.X.X, where each X is a value from 0 to 255. The alphabetic object name
is upper- and lower-case sensitive. You need an IP address if agent/SNMP
communicates with SNMP management stations using the TCP/IP protocol.
