Link Layer Discovery Protocol

– 420 –

◆

Port Description – A string that indicates the port’s description. If RFC

2863 is implemented, the ifDescr object should be used for this field.

◆

Port ID – A string that contains the specific identifier for the port from

which this LLDPDU was transmitted.

◆

System Capabilities Supported – The capabilities that define the

primary function(s) of the system. (See

Table 25, "System

Capabilities," on page 417

◆

System Capabilities Enabled – The primary function(s) of the

system which are currently enabled. (See

Table 25, "System

Capabilities," on page 417

◆

Management Address List – The management addresses for this

device. Since there are typically a number of different addresses

associated with a Layer 3 device, an individual LLDP PDU may contain

more than one management address TLV.
If no management address is available, the address should be the MAC

address for the CPU or for the port sending this advertisement.

Port Details – 802.1 Extension Information

◆

Remote Port VID – The port’s default VLAN identifier (PVID) indicates

the VLAN with which untagged or priority-tagged frames are

associated.

◆

Remote Port-Protocol VLAN List – The port-based protocol VLANs

configured on this interface, whether the given port (associated with

the remote system) supports port and protocol VLANs, and whether the

port and protocol VLANs are enabled on the given port associated with

the remote system.

◆

Remote VLAN Name List – VLAN names associated with a port.

◆

Remote Protocol Identity List – Information about particular

protocols that are accessible through a port. This object represents an

arbitrary local integer value used by this agent to identify a particular

protocol identity, and an octet string used to identify the protocols

associated with a port of the remote system.
