• System Capabilities Enabled – The primary function(s) of the system which are currently
enabled. (See Table 172 on page 921.)
• 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-based protocol
VLANs, and whether the port-based 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.
Port Details – 802.3 Extension Port Information
• Remote Port Auto-Neg Supported – Shows whether the given port (associated with remote
system) supports auto-negotiation.
• Remote Port Auto-Neg Adv-Capability – The value (bitmap) of the
ifMauAutoNegCapAdvertisedBits object (defined in IETF RFC 3636) which is associated with a
port on the remote system.
