ExtremeWare XOS 11.3 Concepts Guide
153
NOTE
The system description TLV is automatically enabled once you enable LLDP and is always sent as part of the
LLDPDU. Although this TLV is not mandatory according to the standard, the ExtremeWare XOS software includes this
TLV in all LLDPDUs by default; you can configure the system not to advertise this TLV.
This section discusses the following optional TLVs:

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
ExtremeWare XOS implementation sends this TLV, by default, whenever you enable LLDP on a port.
You can disable sending this TLV once you enable LLDP; but, by default, the system sends this TLV.
When enabled, the system sends the image information (from the
show version
command) in the
system description TLV:
