Device capability, network policy, PoE status and location data
The medTlvEnable option on the switch is enabled in the default configuration and supports the following LLDP-MED TLVs:
- LLDP-MED capabilities: This TLV enables the switch to determine:
Whether a connected endpoint device supports LLDP-MED
Which specific LLDP-MED TLVs the endpoint supports
The device class (1, 2, or 3) for the connected endpoint
Network policy operating on the port to which the endpoint is connected (VLAN, Layer 2 QoS, Layer 3 QoS.)
PoE (MED Power-over-Ethernet.)
Physical location data.
LLDP-MED operation requires the macphy_config
TLV subelement (enabled by default) that is optional for IEEE 802.1AB
LLDP operation. For more information, see the dot3TlvEnable
macphy_config
command.
