– 377 –
◆
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 26, "System
Capabilities," on page 374 .)
◆
System Capabilities Enabled – The primary function(s) of the
system which are currently enabled. (See Table 26, "System
Capabilities," on page 374 .)
◆ 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.
