Great! We love to see IXP Manager being used around the world :-)

Okay - is there any error? What make and model of switches are you using?

calculated based on the ifHighSpeed of the switch port which requires
SNMP to work.
If we can solve the SNMP issue above and get SNMP switch polling 
working, this will all solve itself.
