About trap management

Trap management enables you to ensure that traps received from network devices are forwarded to ports where they can be handled by Network Manager and other network management systems.

In most networks, traps arrive on a single default port (usually port 162). This can cause problems if you have Network Manager and another network management system installed on the same server. Both of these systems might need to listen for traps; however, only one process can bind to one port at a time.

The SNMP Trap Multiplexer is a Network Manager process that resolves this problem: it listens to a single port and forwards all the traps it receives to a set of host/socket pairs.

By default, the SNMP Trap Multiplexer listens for traps on port 162, but you can change this by inserting an alternative port number into the trapMux.config database table.

The ncp_trapmux process can also store trap events in a binary format file (containing trap and timing information) that can be used to recreate the trap events in the order they occurred at a later date. This is useful mainly for debugging purposes.
