[ixpmanager] Aggregate graphs break graphing

[Miku, E. Cornelius]

Hi Barry,

>From the web front end it just says "Could not query a.b.c.d via SNMP"
I could give you the logs just let me know which log file.

I was using a Cisco 2960 before but currently using a TP-LINK TL-SG3424.

Thanks & Regards,
