Jan 21 2017 at 0012 UTC You will need to setup the phone VLAN first setup DHCP with option 66 for tftp and option 144 for VLAN tag on the phones.

Ip phone vlan. Configure vlan x voice tagged x The voice command is what will force the phone to be placed in your phone VLAN. DHCP service is on and DHCP scope for IP Phone are correctly configured on DHCP server 19216810254. Untaged packets will be broadcasted fro.

On our cisco switch when port is configured with data and voice vlan the phone picks up an IP address from the data vlan and in turn doesnt register. Tag the phone on the port facing the phones and also untag your data VLAN on that same port. The Cisco IP Phone and a device attached to the phone cannot communicate if they are in the same VLAN and subnet but use different frame types because traffic in the same subnet is not routed routing would eliminate the frame type difference.

Those Polycom phones use LLDP to send discovery requests which is how they figure out which VLAN to be on. I understand with just 2 ports its not possible to fit 3 different devices but I guess if the user just wants VoIP feature along with internet then it should be supported. If using DHCP when the IP phone starts it first makes a DHCP request without a VLAN tag.

VLAN 12 are configured on all network devices. The command voice vlan dot1p Instructs the switch port to use 802. The Admin username of NEC is ADMIN password is 6633222.

When the switch is connected to a Cisco 7960 IP Phone the phone sends voice traffic with Layer 3 IP precedence and Layer 2 class of service CoS values which are both set to 5 by default. A workstation can be connected via the PC port on the IP phone in the default or different VLAN. The PC port will work only with the switchports access vlan ID.

Once that is done you can tag the VLAN on your managed switches reboot one phone and test. The phone will also discover what the voice VLAN ID is. If the DHCP reply contains a new VLAN setting as part of the SSON scope the phones will release all its existing IP address and makes a new DHCP request using the newly supplied VLAN ID If the IP Phone does not get a new VLAN ID it will continue with the settings provided in the original DHCP reply.
