4.2.3. Configure the Voice and Data VLAN for the FS726TP
For this configuration 135 was selected as the Voice VLAN and 100 as the Data VLAN. The
choice of 135 for the Voice VLAN and 100 for the Data VLAN can be changed as appropriate
for the LAN where the FS726TP is being used. Different values can be used but the Voice QoS
policy must be established end-to-end in the enterprise.
Select VLAN from the right hand menu. Select IEEE 802.1Q VLAN in the right hand window.
If a pop-up box appears select OK. From the pull down menu select Add new VLAN. In the
box to the right, enter the Voice VLAN ID (135). For each of the 12 PoE ports select U (Untag
egress packets). For the uplink port that will be used to connect the FS726TP to the router, select
T Tag egress packets. Leave the reminder of the ports out (Not member) of the Voice VLAN.

Select Apply. Repeat the process to create the Data VLAN (100).
Note that this configuration is removing the tags (U) from Voice and Data packets going towards
the telephones. This is consistent with the recommendations in the Avaya IP Telephony
Implementation Guide [1]. The telephones will ignore the IEEE802.1Q. Additionally some NIC
cards can be confused by IEEE802.1Q tags so removing the tags reduces the chance of that
conflict occurring.
