Configure more than one channel selector

Use the Channel Selector for the Trap Port setting, but also to set the number of Simultaneous Requests you want to make to your managed devices.

• With multiple simultaneous requests configured, tests have shown an improvement in throughput and performance.

• Even without multiple simultaneous requests, using the default setting (1), a new thread is created for each new Channel Selector. Multiple threads instead of single one, will also improve performance.

If you observe performance issues in your SNMP configuration, we recommend the following hierarchy:

1. Create one Channel Selector for the devices from which you want to receive traps.

2. Create additional Channel Selectors to improve performance of the Communication Driver and to use simultaneous connections for devices from which you don't want to receive traps, but from which you want to process values for greater numbers of OIDs.

   Note: A limitation of multiple Channel Selectors or a channel selector with enabled simultaneous requests is that these configurations will show higher memory and CPU usage by the Communication Driver.
