SNMP Driver Polling Issue in Redundant System

[paramesh1985]

Hi,

We are using SNMP driver to receive the SNMP trap signal from Passeler system.

We are not able to send the active server information to Passeler.

For that reason Passeler system is sending the same trap signal to both the redundant server A and B independent of which server is active.

But now both the server is polling the information. We want only the active server should receive the trap signal and passive server will discard the message.



As per the help file i entered the below mentioned config entry;

[SNMPDrv_3]
OnlyActivePolls = "Yes"

But its not working. Still we are polling the trap signal in both the sever.

Hi,

SNMP Traps are sent unsolicited by the agent (In your case the Passeler system.)

So for receiving traps there is no polling required. Therefore also the config
entry OnlyActivePolls has no influence.

But in any case if the Passeler system sends the traps to both SNMP driver in a redundant
WinCC OA system, the passive Event manager will discard the resulting value change message
and so you should receive the Trap only once in your system.

best regards
