Chapter 6.  LLDP  
NETGEAR 8800 User Manual 
You can configure an optional TLV to advertise or not to advertise the device’s management 
address information to the port’s neighbors. With XCM8800, when enabled, this TLV sends 
out the IPv4 address configured on the management VLAN. If you have not configured an 
IPv4 address on the management VLAN, the software advertises the system’s MAC address. 
LLDP does not send out IPv6 addresses in this field. 
Supported TLVs
The TLVs are contained in the LLDPDU portion of the LLDP packet, and the LLDPDU cannot 
exceed 1500 bytes. Some TLVs are mandatory according to the 802.1ab standard, and the 
rest are optional. The mandatory and system description TLVs are included by default as 
soon as you enable LLDP. The system description TLV is enabled by default on the 
XCM8800 LLDP implementation. Additionally some TLVs can be repeated in one LLDP.
Note:  
To avoid exceeding the 1500-byte limit, NETGEAR recommends 
sending information on only one or two VLANs on the LLDP port. 
Any TLVs that exceed the limit are dropped.
The following TLVs are enabled by default when LLDP transmit is enabled on a port:
•     
Chassis ID
•     
Port ID
•     
Time to live
•     
System description
•     
End-of-LLDP PDU
All of these TLVs that are sent by default are mandatory for the protocol and cannot be 
disabled, except the system description. You can configure the system not to advertise the 
system description when LLDP is enabled; the other four TLVs cannot be configured not to 
advertise. 
 lists all the defined TLVs, if they are included by default after you enable 
LLDP, if they can be configured, if they are mandatory or optional, and if you can repeat that 
TLV in one LLDP packet.
