Configuring Security, Quality, and Network Features
Configuring VLAN Settings for IP Phones
Cisco Small Business SPA300 Series, SPA500 Series, and WIP310 IP Phone Administration Guide 151

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.
NOTE 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.
Default QoS for SIP Mode
If there is no network policy from CDP or LLDP-MED, the default network policy is
used. CoS is based on configuration for the specific extension. It is applicable only
if the manual VLAN is enabled and manual VLAN ID is not equal to 0, 1, or 4095.
ToS is based on configuration for the specific extension.
