Voice and Data Vlans

[Malcolm2]

I need to setup a switch (X460P) to be able to use a VOIP Phone (Polycom) and to be able to use a PC also. The PC MIGHT be plugged into the phone, or there may not be a phone at all, just a PC plugged into a port.

All ports on the switch would need this ability.
So far, I would do this:
Create Vlan Voice tag 10
Config Voice IPAddress 192.168.102.2/24
Config voice add ports 1-48 tag
config vlan default ipaddress 192.168.100.2/24
config vlan default add ports 1-48
ena ipforward voice
ena ipforward default
Config iproute add default 192.168.100.250

I would configure DHCP for each vlan

Now comes my real question.
How does the switch know that I'm plugging in a phone, rather than a PC (or printer or other device). ? I want the voice vlan to get DHCP from the scope I create for Voice, but if a PC gets plugged in, I want DHCP from the data scope I create.
How it know?

The commands are for switches with XOS operating system - the C3 uses EOS.

Take a look into this KB article for EOS...

Hello Marcus!

We have 2 Enterasys (C3G124-48, 48 ports) in our network, the rest are Cisco.

We are implementing Asterisk with IP telephones (cisco 7911) so we have a somewhat complicated scenario.

We have a voice Vlan (303)
We have a data vlan (1)

How do we configure the 44 ports of the Enterasys (1-44)?

The Trunk nodes for the voice vlan were configured with:

set vlan egress 303 ge.1.45-48 tagged

The show vlan portinfo command shows us

Port VLAN Ingress Egress
Filter Vlan

ge.1.45 1 N tagged: 1,303
ge.1.46 1 N tagged: 1,303
ge.1.47 1 N tagged: 1,303
ge.1.48 1 N tagged: 1,303

How do we configure the nodes so that the phone takes the address of the dhcp (172.15.1.x) and the PC of the user that is in the port of the phone take the DHCP Ip (172.16.x.x, data segment with vlan 1)?

We appreciate your valuable help.

The Cli commands that you give up lines did not work with us.

Thanks everybody. This has been helpful!

Hello,

Usually the DHCP server phone PABX or Telefone central...every time when the device ask for ip address inside SVI, the dhcp server through option 82, reply with correct ip address for each device...Usually ip phones have vlan id default depends of vendor, and many central have feature for not delivery ip address for PC just for phones too, you can use this option on you central.

Thanks!

Here is an article that explains the configuration for lldp with a polycom phone:

Hope this helps!
