Hi,

Does anyone know the correct way to configure a voice port on Cisco 3550? Cisco seem to use different config on every switch family.. it is a bit confusing..

eg: Voice vlan:100 with 802.1Q Frames, data vlan: 50.

it this the correct config??

!

interface FastEthernet0/10

switchport access vlan 50

switchport mode access

switchport voice vlan 100

spanning-tree portfast

!

also, how to config the switch if voice vlan use 802.1p Priority-Tagged Frames?

thanks

regards,

sean

I can go through the steps individually but I think it is more appropriate if you read it in detail from the relevant portion of the configuration guide:

http://www.cisco.com/en/US/products/hw/switches/ps646/products_configuration_guide_chapter09186a00801cdf35.html

If you still have specific questions we are here to help out.

Thanks. i have read the doco before.

my question is:

do i need to manually set the port to "access"? if yes, how does IP hone set the COS?

Hi

The switch is going to detect it through CDP and set the COS values.make sure u have enabled CDP on the ports.

Thanks

does it mean i only can use this config on Cisco ip phone?

could someone show me the 802.1p with data vlan switch configuration example. thanks.
