Link Layer Discovery Protocol
Current Capabilities – The set of capabilities that define the primary
◆
function(s) of the port which are currently enabled.
Port Details – Network Policy
Application Type – The primary application(s) defined for this
◆
network policy:
Voice

Tagged Flag – Indicates whether the specified application type is
◆
using a tagged or untagged VLAN.
Layer 2 Priority – The Layer 2 priority to be used for the specified
◆
application type. This field may specify one of eight priority levels
(0-7), where a value of 0 represents use of the default priority.
Unknown Policy Flag – Indicates that an endpoint device wants to
◆
explicitly advertise that this policy is required by the device, but is
currently unknown.
VLAN ID – The VLAN identifier (VID) for the port as defined in IEEE
◆
802.1Q. A value of zero indicates that the port is using priority tagged
frames, meaning that only the IEEE 802.1D priority level is significant
and the default PVID of the ingress port is used instead.
DSCP Value – The DSCP value to be used to provide Diffserv node
◆
behavior for the specified application type. This field may contain one of
64 code point values (0-63). A value of 0 represents use of the default
DSCP value as defined in RFC 2475.
Port Details – Location Identification
◆
Location Data Format – Any of these location ID data formats:
Coordinate-based LCI
■
resolution, latitude, longitude resolution, longitude, altitude type,
altitude resolution, altitude, and datum.
