Control of the IP Phone 802.1Q
The 802.1Q header in the outgoing packets from the IP Phones is enabled
by one of the following:
•
•
•
802.1Q and the Voice Gateway Media Cards
The Voice Gateway Media Cards cannot send the 802.1Q header because
the card operating system does not support it. The switch ports connecting
the Voice Gateway Media Card TLAN network interface should be
configured for untagged operation so if a 802.1Q header is present, it is
stripped before a packet is passed to the card.
The configuration in TM 3.1 and Element Manager is for the control of the
priority bits in the 802.1Q header sent by the IP Phones only.
Three-port switch support
The IP Phone three-port switch does not interpret the 802.1Q header.
Instead, the three-port switch allows the packets to pass through unmodified.
Packet priority is achieved on a per-port basis. IP Phone port traffic has a
higher priority than traffic for the Ethernet port to which the PC is connected.
An IP Phone can receive broadcast frames from a PC data VLAN. Any
broadcast storm packets from the data network are seen by the IP Phone.
However, this type of traffic does not adversely affect the IP Phone.
Data Path Capture tool
IP Line contains the Data Path Capture tool, a built-in utility used to capture
audio information. This tool helps debug audio-related gateway problems
and allows after-the-fact analysis of what the user heard.
The Data Path Capture process is controlled by a set of CLI commands.

pool per subnet and VLAN is used. A relay agent is required if it is
a PC-only network.
If the IP Phone VLAN GUI response is set to 1, then the 802.1Q
functionality is enabled. All packets from the IP Phone have the 802.1Q
header as part of the Ethernet frame.
If the IP Phone VLAN GUI response is set to 2, then the 802.1Q
functionality is enabled after the DHCP response is received with the
VLAN ID.
If the TM or Element Manager configuration enables the use of the p bits,
after downloaded to the IP Phone, the 802.1Q functionality is enabled.
