For the "Inter-Switch / Trunk Graphs", we briefly mention these in the
docs: https://docs.ixpmanager.org/grapher/mrtg/#backend-mrtg

So, since 2018 we have actually worked on it and finished it but we need 
to document, code review and then release. In the mean time the old way 
still works but it's manual.

You need a skinned config file like:

https://github.com/inex/IXP-Manager/blob/v5.0.0/resources/skins/inex/services/grapher/mrtg/trunks.foil.php

and then a 'config/grapher_trunks.php' file based on this:

https://github.com/inex/IXP-Manager/blob/v5.0.0/config/grapher_trunks.php.dist

This config file generates the menu and links it to the appropriate 
graph in the config file.

And be sure to set GRAPHER_BACKEND_MRTG_SNMPPASSWD="xxx" in the .env file.


Yeah, sorry, this is awkward. But we should have a better way in the 
next few weeks.


For "VLAN / Per-Protocol Graphs", you need to configure and enable sflow 
p2p graphs:

Hope this helps,
