This field shows the primary function of the neighboring device. The possible application types are:
Voice: This is for dedicated IP phones. These devices are typically deployed on a separate VLAN for ease of deployment and enhanced secu-

Voice Signalling: This is for network topologies that separate voice media and signalling policies.

Guest Voice: This supports a limited feature-set voice service for guests with their own IP phones.

TAG:

This field shows whether the specified application type is using a tagged or an untagged VLAN. The possible application types are:
Untagged: The device is using an untagged frame format and as such does not include a tag header as defined by IEEE 802.1Q.

Tagged: The device is using the IEEE 802.1Q tagged frame format.

VLAN ID:

This field shows the VLAN identifier (VID) for the port as defined in IEEE 802.1Q-2003. A value of
ID. A value of 0 (Priority Tagged) is used if the device is using priority tagged frames as defined by IEEE 802.1Q-2003, meaning that only the IEEE
802.1D priority level is significant and the default PVID of the ingress port is used instead.
