Customer has snmp listening on several non standard ports. I have to edit all the items of the customer, and specify the snmp-port.

For the SNMP community I don't have to do it: I define a macro like {$SNMPCOM} for the host and reference it from inside the item. This method is not allowed for the snmp-port, because no macro is allowed in the field.

So I would like to request a new feature: that the snmp-port value inside an item may not only be a value, but also a macro.

Is it a good idea?

from the manual:
