Link Layer Discovery Protocol
– 352 –
◆ System Capabilities Supported – The capabilities that define the primary
function(s) of the system. (See Table 23, "System Capabilities," on page 348 .)
◆
System Capabilities Enabled – The primary function(s) of the system which
are currently enabled. (See Table 23, "System Capabilities," on page 348 .)
◆ 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.
