Cisco SPA504G - network ports on the back -vlans

Hi,

I have some Cisco SPA504G phones which have Windows computers piggy backed off them using the PC port.

I want to seperate my VOICE and DATA into seperate VLANS.

I have a switch which has VLAN: 10 for VOICE and VLAN: 20 for DATA setup.

How do I go about setting the phone to use VLAN10 and the PC port on the Cisco phone to use the VLAN: 20 DATA?

Hi,

if your switch config looks like below the Phone and PC will get the correct VLAN:

!

interface FastEthernet1/0/2

switchport access vlan 20

switchport mode access

switchport voice vlan 10

spanning-tree portfast

Thanks for this. Does the phones need to be plugged into tagged ports? (sorry might be the HP term)

"interface FastEthernet1/0/2" What interface is this referring to?

No guru with cli, by configuring the switch as above, I just plug the phone into any port on the cisco switch?

on a cisco switch the ports is either fastethernet 1/0/1 or fastethernet 0/1 or gigbitethernet 0/1

so on CLI you need to enter conf t mode.

then go to the port number the phones is plugged into say for instance port 4 to port 8

then you can do

interface range fa0/4 - 8

switchport access vlan 20

switchport mode access

switchport voice vlan 10

spanning-tree portfast

exit

exit

wr

so yes you need to configure the ports on the cisco switch in which you plug the phones in.
