enterprise - When sending an SNMP trap, does the agent need to know the port number of the receiver? -


i new snmp. when sending snmp trap, agent need know port number of receiver? or needs know receiver's ip address? , receiver should specify agent's ip + port when subscribes?

when snmp traps sent, port managers listen 162. may happen port different, that's precise purposes. yes agent needs know port of receiver. ip address, yes agent needs know ip address of manager. (when manager here i'm talking receiver).

and receiver should "know" sender's ip in way needs authorize him send traps him. if done in config.

i don't know you're using, net-snmp great tool learn snmp.

hope helps
