I have Cisco LMS 4.2 installed i was using SNMP V2c for polling my devices. After i turned on SNMPv3 all devices are reachable and even when i make credentials check it's ok, but the issue when i access any device from search pane it shows me in the collector status " Discovery failure"
Steps i made to troubleshoot but not succeeded :
1. Rediscover Devices
2. Modify SNMP timeout & retry settings
Devices: Catalyst 2960 , Catalyst 3560
I've attached a snapshot of collector error
