I configured my devices with snmp v3 authnopriv. On all devices I configured snmp context for all vlan.:-( Is it necessary for LMS 3.1 to configure snmp context for all vlans? I had to configure cca. 40 snmp contexts;-( But when I used device discovery and data collection, the links between devices are red dashed:-( Without contexts these links were discovered correctly.. I use IE 7.0.5730. What is recommendation setting for network where few devices are Cat2950 and the rest devices are 2960,3560 ,and 3750?? Is possible to configure snmpv3 with context configuration (on Cat2950 - it isn't possible) or configure all devices with snmp v2c??? Thank you.
