I just installed UDT 3.3 (30 days test license) on our environment (NPM 12.2, NCM 7.7, IPAM 4.5.2)
I added 2 switches to our UDT for testing. 1 core switch and 1 access switch.
Did a port discovery for those devices and they are now showing on UDT.
BUT... I can't see the VLAN or MAC Address that are on the ports.
I then added a device to the watch-list and I can see that it get's the correct VLAN and Subnet but it tracks it to the Layer 3 interface on the Core switch and not on the interface on the access switch.
Does anyone have the same issue?
BTW my access switch is a Cisco Catalyst 2960-X.
on the Discovery I marked it to get Layer 2 and Layer 3 Topology.
After opening a support case I found where the issue was.
To get the mac address information of a vlan on a switch you need to allow context on snmp (If your switch support it)
Here is a link describing this:
