Multiple NIC and SNMP issues?

kenshin138

We are using ipMonitor 10 to monitor about 400 servers right now. We are moving forward with a new backup system that runs on a separate network. To make this work we are installing a secondary NIC in all of our systems. On my ipMonitor box after I installed the secondary NIC I started getting SNMP failures on most systems. So my question is, is this normal?

Setup:
NIC Team: internal network (default gateway set)
Secondary NIC: backup network  (no default gateway)

We are registering DNS for both as well. I'm trying to determine if the second NIC/network caused the issue or if it was something else. Using a SNMP test utility it would fail as well. I have since disabled the secondary NIC and things seem ok, but I did have to restart a great many systems' SNMP service before they came back online.

If it did cause the problem, is there a way to make ipMonitor only work via one of the connections? We aren't using Traps at all, just simple SNMP for things like drive space, CPU, etc.

Thanks!

    Hi guys, I see this is an old post but I still have a question about SNMP with multiple NIC's.

    I have 1 Server with 5NIC's all running static IP addressees. Adding the system to Orion, I needed to figure out witch IP address would respond on the SNMP Community String.
    Once added to the Orion database the machine showed all the graphs I need. But.. when I rebooted the machine, Orion did not get any more SNMP data from the machine, only ping.

    So.. the responding IP address for SNMP was changed (Interface or IP picked by Windows I guess).
    Once I changed the IP address in Orion NPM, I received all readouts again.
    I gave the machine another reboot to see if it would change again, and it did.. so now my question...

    Can I bind the SNMP polling only to 1 interface and/or IP address ?

    Hope I was clear enough. Thanks guys!!
