Elixir and Erlang both run on the same virtual machine (BEAM), and it’s possible to call Erlang functions from Elixir.

For example, here’s the syntax for calling the date/0 (0-argument function, date) in the erlang module.

iex(1)> :erlang.date()
{2019, 5, 23}

Similarly, to run Erlang’s interactive SNMP configuration generator, config/0 in the snmp module you’d type:

iex(2)> :snmp.config()

Simple SNMP configuration tool (version 5.2.11)
------------------------------------------------
Note: Non-trivial configurations still has to be
      done manually. IP addresses may be entered 
      as dront.ericsson.se (UNIX only) or
      123.12.13.23
------------------------------------------------

Configure an agent (y/n)? [y]

Erlang ships with a lot of SNMP-related modules and functions, so looking through the docs I linked and tinkering around in iex should give you a sense whether it supports what you need.

Why not use Erlang’s library directly?
