Insight Manager SNMP Traffic

[David Turner_5]

Do the SNMP clients push data or does it get pulled. We have some servers in a DMZ and want to manage them through a firewall. I need know what direction the traffic is flowing.
Thanks for any help

hpSIM and IM7 use SNMP on the wire for 4 basic purposes: device identification (pull), status polling (pull), data collection (pull) and event traps (push)--from the perspective of the agent. You do need to have both directions enabled because of the request/reply model of the pull functions.

In terms of firewall you have to open port 161 from HPSIM server to the managed servers, so HPSIM will be able to read (pull) the devices. And you will need to open port 162 from managed servers to the HPSIM server, so the managed servers will be able to sent traps.
