We have problem with UT in Campus Manager, there are no any hosts there. UT starts and finished without results.
In accordance with https://supportforums.cisco.com/message/2007198 (thanks to Joseph) we have changed our config and it has started to work.
snmp-server group writeonly v3 auth context vlan-xxxx
But there are huge amount devices and huge amount of vlans need to be configured.
Is there any workaround?
