Hi Oliver,

This is off the top of my head, so not perfect, but you need something
like this...

control-plane
 management-plane
  inband
   interface XXX
    allow SNMP peer
     address ipv4 172.20.18.0/28

Have tried the various debug commands to see why your packets are
being dropped? If not, add the control-plane rule above, then run some
debugs and report back to the list what you see in the logs.

Cheers,
James.
