IP Phone problem

[tolganetwork]

Hello Community

Clients taking IP from the untagged vlan subnet as wanted but also Phones taking IP from the untagged vlan subnet. That shouldnt be like this.
In other vendor switches phones taking IP from the voice vlan with same config. Phone settings are default, auto negotiation and LLDP enabled.

Phone Model : SIP T46S
Topology connection is switch --> Phone --> Client
My switch config 

Summit # create vlan voice
Summit # configure vlan voice tag 10
Summit # configure vlan voice add port 1,11-12 tagged
Summit # create vlan data
Summit # configure vlan data tag 11
Summit # configure vlan data add port 1 tagged
Summit # configure vlan data add port 5,11-12 untagged

Also i tried QOS config template but did not work either.

Summit #create qosprofile qp7
Summit #configure diffserv examination code-point 46 qp7
Summit #config dot1p type 6 qp7
Summit # enable diffserv examination port 1
Summit # disable dot1p examination port 1

Can somebody help me to figure out.

It is better described in this article.

You need something like below.

• configure lldp port <port number> advertise vendor-specific med capabilities
• configure lldp port <port number> advertise vendor-specific dot1 vlan-name vlan <VOIP vlan>

Do you know if the phones use CDP or LLDP to "move" to the voice vlan?

If using LLDP, you may need something like the following added:
