VLAN Set up

[Mojo1]

We currently have our ip phones running over the network. What is the first step in setting them up to be on their own VLAN?

[thisisshanky]

Its a good idea to keep vlans separate for phones and Pcs, especially if you are daisy chaining PCs to the phones. For a smaller network, you will need,

a. two vlans - one data vlan, one auxiliary vlan (voice vlan)

b. two subnets (one for data, one for phones)

For a IOS based switch,

here is a sample,

vlan 100

name Data

vlan 200

name Voice

int vlan 100 (if l3 switch)

ip add 10.10.10.1 255.255.255.0

int vlan 200

ip add 10.10.20.1 255.255.255.0

ip dhcp pool Phones

network 10.10.20.0/24

default-router 10.10.20.1

option 150 ip

ip dhcp pool Data

network 10.10.10.0/24

default-router 10.10.10.1

individual port configuration -

int fa0/1

switchport mode access

switchport access vlan 100

switchport voice vlan 200

spanning-tree portfast

You can apply the same config to rest of the ports using the range command.

You should also enable QOS on the switch. QOS configs are different for different switches, so that topic would be something that I would recommend you to read the following link..its a lot to read..
