Dear Observium community,

we have got some  misleading port info in D-Link xStack switches. First stack always show nice and clear port number, but the second one jumps ~60 ports up for unknown reason. Same thing with third, fourth etc. Other monitoring soft like Cacti or Zabbix showing the same graphs.

D-Link support refuses to make output corrections and tells us the formula:

(port + 64*(unitID – 1))

Can we make a fix?

Thank you.
