Network Statistics
The following network statistics hyperlinks on a phone’s web page provide information about network
traffic on the phone. To display a network statistics area, access the web page for the phone as described
in the
Accessing the Web Page for a Phone, page 8-2 .
Span to PC Port Indicates whether the phone will forward packets transmitted and received on the network
port to the access port.
PC VLAN VLAN used to identify and remove 802.1P/Q tags from packets sent to the PC.
Forwarding Delay Indicates whether the internal switch begins forwarding packets between the PC port and
switched port on the phone when the phone becomes active.
LLDP: PC Port Indicates whether Link Layer Discovery Protocol (LLDP) is enabled on the PC port.
LLDP-MED: SW Port Indicates whether Link Layer Discovery Protocol Media Endpoint Discovery
(LLDP-MED) is enabled on the switch port.
LLDP Asset ID Identifies the asset ID assigned to the phone for inventory management.
Wireless Headset
Hookswitch Control Enables users to receive notifications of incoming calls and answer or end calls while
working in a wireless environment.
LLDP Power Priority Advertises the phone’s power priority to the switch, enabling the switch to appropriately
provide power to the phones. Settings include:
• Unknown—default
• Low
• High
• Critical
CDP: PC Port Indicates whether CDP is supported on the PC port (default is enabled).
Enable CDP on the PC port when Cisco VT Advantage/Unified Video Advantage (CVTA)
is connected to the PC port. CVTA does not work without CDP interaction with the phone.
Note When CDP is disabled in Cisco Unified Communications Manager, a warning is
displayed, indicating that disabling CDP on the PC port prevents CVTA from
working.
Note The current PC and switch port CDP values are shown on the Settings menu.
CDP: SW Port Indicates whether CDP is supported on the switch port (default is enabled).
• Enable CDP on the switch port for VLAN assignment for the phone, power
negotiation, QoS management, and 802.1x security.
• Enable CDP on the switch port when the phone is connected to a Cisco switch.
Note When CDP is disabled in Cisco Unified Communications Manager, a warning is
presented, indicating that CDP should be disabled on the switch port only if the
phone is connected to a non-Cisco switch.
Note The current PC and switch port CDP values are shown on the Settings menu.
