Standards-based TLVs
Note: The system description TLV is automatically enabled after you
enable LLDP and is always sent as part of the LLDPDU. Although
this TLV is not mandatory according to the standard, XCM8800
software includes this TLV in all LLDPDUs by default; you can
configure the system not to advertise this TLV.
This section describes the following optional standards-based TLVs:
• Port description TLV on page 160
• System name TLV on page 160
• System description TLV on page 160
• System capabilities TLV on page 161
• Management address TLV on page 161
• VLAN name TLV on page 161
• Port VLAN ID TLV on page 161
• Port and protocol VLAN ID TLV on page 162
• MAC/PHY configuration/status TLV on page 162
• Power via MDI TLV on page 162
• Link aggregation TLV on page 162
• Maximum frame size TLV on page 163
Port description TLV
You configure this TLV to be advertised or not advertised. The port description TLV contains
the ifDescr object, which is the ASCII string you entered using the
configure ports
display-string
command. If you have not configured this parameter, the TLV carries an
empty string.
System name TLV
You configure this TLV to be advertised or not advertised. The system name TLV contains the
device’s configured system name, if previously configured using SNMP. This is the sysName
as defined in RFC 3418, which you define using the
configure snmp sysname command.
System description TLV
This is the only TLV that is enabled by default but not mandatory according to the standard.
The XCM8800 implementation sends this TLV, by default, whenever you enable LLDP on a
port. You can disable sending this TLV after you enable LLDP; but, by default, the system
sends this TLV.
