a problem with UT and SNMPv3

[ROMAN TOMASEK]

The customer uses LMS2.6. He had used SNMPv1 for management Cisco devices by the LMS. The funcionality of LMS was OK. He changed the SNMP v1 to SNMPv3 (AuthNoPriv) and some problem with UT occured. Some end devices are not discovered using UT. The switches, where the end devices are connected, are discovered and displayed in the Topology View (the state is green). This behaviour is for different type of switches. These switches are available using SNMPv3. Do you have any idea for solving this problem? Thank you.

When you migrate to SNMPv3, you must allow LMS to poll SNMPv3 contexts to get the STP and end host information. The problem is not all switches support SNMPv3 contexts. These posts may help you:
