We have two very similar Aruba switch devices. For one of the devices, the VLAN information is shown directly under the physical ports, once you expand the physical interface from the interface tab you can see which VLAN that port belongs too and this is our preferred method.
For the other Aruba device, we see that the VLANs are being displayed at the same level in the interface tab, therefore we do not know which VLANs are assigned to each interface.
Why does Spectrum provide this information for 1 device but not the other?

The device that does not show the VLANs under the physical port does not support the Q-BRIDGE-MIB.
