The problem is that i keep getting an alert about snmp authentication failure wrong community name. I verified that both ends have the same community name. When i also try to do an snmpwalk every thing works no problem i tried v1 and v2c. Same thing i did with opennms changed from v1 to v2c but nothing still the same error. The weird thing is that it graphs SNMP node data but not the interface. The device that im using is a FortiWLC MC1550.
