When we do a topology discovery using Campus Manager version 3.1, the layer-2 view shows 15 devices are discovered. However, the VTP domain view shows only 5 devices discovered. We have check the configuration for the 10 undiscovered devices and confirmed that they belong the same VTP domain as the 5 discovered devices.
1) All the devices are Cat4006 running the same CatOS 6.3.3
2) All switches are CDP enabled
Kindly advice. Thx.
