Note: If you want to send traps for LLDP MED, you must configure it
separately. Use the enable snmp traps lldp-med {ports
[all | <port_list>]} command to enable these traps.
Configuring Optional TLV Advertisements
By default, all optional TLVs are not added to the LLDPDU, or not advertised.
You can add optional TLVs to the LLDPDU but be aware that the total LLDPDU cannot
exceed 1500 bytes, including the mandatory TLVs. Any optional added TLVs that exceed the
1500-byte limit are dropped. You can see if you have dropped TLVs from your LLDPDU by
referring to the EMS log or by issuing the
show lldp statistics command.
Note: NETGEAR recommends that you advertise only one or two VLANS
on specified ports to avoid dropping TLVs from the LLDPDU.
This section describes the following types of optional TLVs:
• Configuring Standards-based Optional TLVs on page 167
• Configuring LLDP MED Optional TLVs on page 169
Configuring Standards-based Optional TLVs
You configure LLDP ports to advertise any of the following optional TLVs:
• Port description TLV
• System name TLV
• System capabilities TLV
• Management address TLV
• VLAN name TLV (repeatable TLVs)
• Port VLAN ID TLV
• Port and protocol VLAN ID TLV (repeatable TLVs)
• MAC/PHY configuration/status TLV
• Power via MDI TLV
• Link aggregation TLV
• Maximum frame size TLV
See Standards-based TLVs on page 160 for complete information on each optional TLV.
