MSM7xx Controllers Configuration Guide v6.4.0

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 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
(Only supported on the HP 517 or MSM317.)
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:
DescriptionTLV name
Indicates the supported capabilities on the device by setting the
appropriate bit to 1.
LLDP-MED Capabilities
• Bit 0: LLDP-MED Capabilities
• Bit 1: Network Policy
• Bit 2: Location Identification
• Bit 3: Extended Power via MDI - PSE
• Bit 4: Extended Power via MDI - PD (not supported)
• Bit 5: Inventory inventory
• Bits 6-15: Reserved
The network policy TLV is a fixed length TLV that indicates a port VLAN
type, VLAN identifier (VID), and both the Layer 2 and Layer 3 priorities
associated with a specific set of application types.
Network Policy
Indicates the physical location of the device using the following form:
• Emergency Call Services ELIN, as described for example by NENA
TID 07-501.
Location Identification
Indicates the IEEE 802.1af (PoE) power related information on the device
which includes:
Extended Power-via-MDI
• Power type
• Power source
