LLDP
Configuring LLDP on an AP
17-9
Time to live (Type 3): Defines the length of time that neighbors will consider LLDP
information sent by this agent to be valid. Calculated by multiplying Transmit interval
by the Multiplier.
Optional TLVs
Port description (Type 4): A description of the port.
System name (Type 5): Administrative name assigned to the device from which the TLV
was transmitted. By default this is the SNMP system name. If the Dynamic system name
option is enabled, the system name is replaced by the dynamically generated name.
System description (Type 6): Description of the system, comprised of the following
information: operational mode, hardware type, hardware revision, and firmware version.
System capabilities (Type 7): Indicates the primary function of the device. Set to: WLAN
access point.
Media endpoint discovery (MED) features
The MED LLDP extensions specify two kinds of network devices: network connectivity and
endpoint. Network connectivity devices connect endpoint devices to an IEEE 802-based LAN
infrastructure. This means that HP access points and controllers are network connectivity
devices. Endpoint devices are located at the network edge, and include devices such as IP
phones, IP media servers, and IP communication controllers.
A network connectivity device does not send LLDP-MED TLVs on any port unless it detects
an endpoint device connected to the port and receives LLDP-MED TLVs from the endpoint
device.
The LLDP-MED TLVs supported by HP APs are as follows:
TLV name Description
LLDP-MED Capabilities Indicates the supported capabilities on the device by setting
the appropriate bit to 1.
Bit 0: LLDP-MED Capabilities
Bit 1: Network Policy
Bit 2: Location Identification
Bit 3: Extended Power via MDI - PSE (only supported on
the MSM317)
Bit 4: Extended Power via MDI - PD (not supported)
Bit 5: Inventory inventory
Bits 6-15: Reserved
