## Frequently asked questions

### Difference between SNMP polling and traps?

Polling is scheduled pulls by the manager (UDP 161). Traps are asynchronous pushes from the agent to a receiver (UDP 162). Pull vs push.

### Are SNMP traps reliable?

Classic traps are not reliable—no acknowledgment, UDP can drop them. InformRequest adds ack/retransmit. Still design for loss.

### Should I use traps or polling?

Both, in most production networks. Poll metrics and health; trap (or inform) discrete events. Trap-only or poll-only each leave holes.

### What port do traps use?

UDP 162 on the trap receiver / manager side. Queries use UDP 161 on the agent.
