Before installing SNMP Manager, you must ensure that all the correct ports are open, so Security Center can communicate properly with SNMP devices.

The following table lists the default network ports that are used by SNMP Manager.

Computer Inbound Outbound Port Usage Configurable
The Security Center server that hosts the plugin role UDP 162   Listen for notifications (SNMP traps and informs) from SNMP devices. No
The Security Center server that hosts the plugin   UDP 161 (default) Polling the objects on SNMP devices to get latest values and states. Yes
NOTE: A UDP port range can be configured for outbound ports to increase polling performance.
