2.2.2. Setting up SNMP in RipEX

As we have mentioned, SNMP agent is always running to answer the queries from SNMP manager.

Generating SNMP traps for alarms can be turned on and set up in Settings menu, section Device, item

Alarm management. For more information see on-line help or chapter Advanced configuration

of the

manual.

2.2.3. Setting up SNMP in manager

It is important to realise that the average size of a single query and response to a specific OID is ap-

proximately 180 Bytes. The following images shows monitoring of part of a communication, with time

stamps, between manager 192.168.131.178 and agent (RipEX) 192.168.141.212. Get-request alternates

with specific OID and get-response. The lower part shows message size and src and dst ports.

Fig. 2.1: Record of communication between manager and agent

The entire MIB for a single RipEX is 10 kilobytes. If SNMP data is downloaded over the radio channel,

SNMP generates significant traffic which can influence network performance (collisions, response

times, etc.). That's why we recommend using the radio channel to query only selected OIDs and not

all data. Set longer SNMP query interval in your manager device. The shortest recommended interval

is minutes to tens of minutes.

If possible, use RipEX Ethernet interface for SNMP communication to relieve the radio channel.
