Hello, Thanks very much for the explanation, Dave. We can now work a solution on the management station end using the added hostname varbind you suggest.

You can append whatever varbinds you like to the payload of the trap. This could potentially include a string varbind, containing the hostname. But always ensure that the varbinds listed in the MIB definition for the trap come first. > 2) If I use the snmptrap command and specify the hostname I am sending it > from, the IP address always appears at the management station end.

The standard structure of an SNMPv1 trap includes a field for the IP address. SNMPv2-style traps don't necessarily include this value, but there is a standard varbind defined for it. But in both cases, this is an IP address, not a hostname. So yes, typically the hostname will be resolved first, and this IP address then sent in the trap.
