Currently, entries in the list of SNMP interfaces in dropdowns have format <address> : <port>.  But to be compliant with requirements  we need to modify this format.

It's proposed to change it by adding SNMP version + community (for SNMPv2c) or SNMP version + security name + context (for SNMPv3).

To reduce clutter we might add these fields only when there are multiple interfaces which cannot be distinguished solely by address and port. For example, if there are two SNMPv2 interfaces with ports 161 and 1161 then we display these as:

127.0.0.1 : 161

127.0.0.1 : 1161

But if there are two SNMPv2 interfaces with communities public and secret then:

127.0.0.1 : 161 : public

127.0.0.1 : 161 : secret

Additionally, community names and SNMPv3 parameters can be truncated to a reasonable length suitable for the dropdown.
