C HAPTER 15 | Basic Administration Protocols
Link Layer Discovery Protocol
– 209 –
ES-2000 Series
Every management address TLV that reports an address that is
accessible on a port and protocol VLAN through the particular port
should be accompanied by a port and protocol VLAN TLV that
indicates the VLAN identifier (VID) associated with the management
address reported by this TLV.
■
Port Description – The port description is taken from the ifDescr
object in RFC 2863, which includes information about the
manufacturer, the product name, and the version of the interface
hardware/software.
■
System Capabilities – The system capabilities identifies the
primary function(s) of the system and whether or not these primary
functions are enabled. The information advertised by this TLV is
described in IEEE 802.1AB.
■
System Description – The system description is taken from the
sysDescr object in RFC 3418, which includes the full name and
version identification of the system's hardware type, software
operating system, and networking software.
■
System Name – The system name is taken from the sysName
object in RFC 3418, which contains the system’s administratively
assigned name. To configure the system name, see "Displaying
System Information" on page 47.
◆ 802.1 Organizationally Specific TLVs – Configures IEEE 802.1
information included in the TLV field of advertised messages.
■
Protocol Identity – The protocols that are accessible through this
interface.
■
VLAN ID – The port’s default VLAN identifier (PVID) indicates the
VLAN with which untagged or priority-tagged frames are associated
(see "IEEE 802.1Q VLANs" on page 93).
■
VLAN Name – The name of all VLANs to which this interface has
been assigned (see "IEEE 802.1Q VLANs" on page 93).
■
Port and Protocol VLAN ID – The port-based protocol VLANs
configured on this interface (see "IEEE 802.1Q VLANs" on page 93).
◆ 802.3 Organizationally Specific TLVs – Configures IEEE 802.3
information included in the TLV field of advertised messages.
■
Link Aggregation – The link aggregation capabilities, aggregation
status of the link, and the IEEE 802.3 aggregated port identifier if
this interface is currently a link aggregation member.
■
Max Frame Size – The maximum frame size. (See "Configuring
Support for Jumbo Frames" on page 50 for information on
configuring the maximum frame size for this switch
