Introduction 85
be on the Data VLAN. If the DHCP server is not
on the Data VLAN, the IP Phone 1140E fails
to receive the DHCP information and fails to
register. In addition, another DHCP server must
reside in the Voice VLAN to provide the network
parameters required. For more information, see
the section on DHCP Auto VLAN Discovery.
4095
All telephony traffic that is transmitted on the
telephony port has an 802.1q header appended
and its Voice VLAN ID is set to the value
manually configured here. Place the cursor over
the 4095 and press the enter NAV key to modify
this value to the desired Voice VLAN tag. Note
that the value 4095 is not a valid VLAN ID. This
is intentional to ensure a proper VLAN ID is
entered.
VLAN Filter
Configure the VLAN Filter (not available if Voice VLAN is set to No).

Result
Enabled (box is checked) Traffic is forwarded to the IP Phone 1140E port,
based on a review of the MAC address of the
packet as well as the 802.1q tag value. Traffic
is forwarded through the IP Phone 1140E port,
(to the network stack of the telephone), only if
the packet matches the MAC address of the IP
Phone 1140E and contains the Voice VLAN tag.
If the Automatic VLAN Discovery feature is used,
the filter is adjusted dynamically as the IP Phone
1140E validates the VLAN suggested by DHCP.
Disabled The VLAN filter is disabled by default. If the
VLAN filter is disabled, traffic is forwarded to the
IP Phone 1140E port based only on a review of
the MAC address of the packet. The IP Phone
1140E accepts traffic addressed to the MAC
address of the IP Phone 1140E as well as any
broadcast or multicast packets from any VLAN.
Disable PC Port
With a disabled PC Port, the IP Phone 1140E with SIP Firmware does not
receive or send packets to or from the PC port. No device can use the
PC port to connect to the network.
