As it turns out SNMP is broken in more ways then just the poll rate. There is only 2 traffic counters on the standard interfaces oid, namely 19 and 20, one of those two is the LAN port (i assume the 20). I have 3 WAN ports active, they don't show up or the traffic is not counted.

Another issue (has been noted in the forums allready) that the set community is gone since the last 2 firmeware updates. 

I conclude that the ER7206 isn't quite ready for business use. 

The Current Firmware fixes the issue of not being able to adress the different WAN ports (1.2.0 Build 20220117 Rel.74491) The issue of a 10 second poll rate remains. Is there a performance reason for this or just an oversight ? Maybe it could be an option, so I could set it to 1 second ? Please respond.
