– 383 –
u
Port Description – A string that indicates the port’s description. If RFC
2863 is implemented, the ifDescr object should be used for this field.
u
Port ID – A string that contains the specific identifier for the port from
which this LLDPDU was transmitted.
u
System Capabilities Supported – The capabilities that define the
primary function(s) of the system. (See Table 22, "System
Capabilities," on page 380 .)
u
System Capabilities Enabled – The primary function(s) of the
system which are currently enabled. (See Table 22, "System
Capabilities," on page 380 .)
u
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.
Port Details – 802.1 Extension Information
u
Remote Port VID – The port’s default VLAN identifier (PVID) indicates
the VLAN with which untagged or priority-tagged frames are
associated.
u
Remote VLAN Name List – VLAN names associated with a port.
u
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
u
Remote Port Auto-Neg Supported – Shows whether the given port
(associated with remote system) supports auto-negotiation.
