LLDP-MED Extended Power-Via-MDI TLV
In the TLV for the outgoing LLDPDU, the binary value for Power Type is set to “0 1”
to indicate the power type for phone is PD Device. The Power source for the
phone is set “PSE and local” with binary value “1 1”. The Power Priority is set to
binary “0 0 0 0” to indicate unknown priority while the Power Value is set to
maximum power value based on phone type:
For the incoming LLDPDU, the TLV is ignored and not validated. Only one TLV is
allowed in the outgoing and incoming LLDPDUs. The phone will send out the TLV
for wired network only.
The LLDP-MED standard was originally drafted in the context of Ethernet.
Discussion is ongoing for LLDP-MED for Wireless Networks. Refer to ANSI-TIA
1057, Annex C, C.3 Applicable TLV for VoWLAN, table 24. It is recommended that
the TLV is not applicable in the context of the wireless network. This TLV is
targeted for use in the context of PoE and Ethernet. The TLV, if added, will not
provide any value for network management or power policy adjustment at the
switch.
LLDP-MED Inventory Management TLV
This TLV is optional for Device Class III. For the outgoing LLDPDU, we support only
Firmware Revision TLV. The value for the firmware revision is the firmware version.
For the incoming LLDPDU, the TLVs are all ignored and not validated. Only one
Firmware Revision TLV is allowed for the outgoing and incoming LLDPDUs.
Final Network Policy Resolution and QoS For the Phone
The following sections describe network policy and QoS for the IP phones.
Special VLANs
VLAN=0, VLAN=1 and VLAN=4095 are treated the same way as an untagged
VLAN. As the VLAN is untagged, CoS is not applicable.
