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.

We have some servers in a DMZ and want to manage them through a firewall. I need know what direction the traffic is flowing.<BR />Thanks for any help Fri, 21 May 2004 07:04:23 GMT https://community.hpe.com/t5/server-management-systems/insight-manager-snmp-traffic/m-p/3283043#M3084 David Turner_5 2004-05-21T07:04:23Z https://community.hpe.com/t5/server-management-systems/insight-manager-snmp-traffic/m-p/3283044#M3085 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.
