I also want to know best configuration.

Senario:
PC traffic :vlan 1
Phone traffic:vlan :31

Whitch is right,trunk or access mode for Voice Vlan?

swi trunk end dot
swi mode trunk
swi trunk native vlan 1
swi voice vlan 31
mls qos trust cos
spanning portfast

or

swi mode acc
swi acc vlan 1
swi voice vlan 31
mls qos trust cos
spanning portfast

PC traffic connected to Phone is untagged traffic. (right ?)

Subject: Data Voice VLAN

Interface FastEthernet0/3
 switchport trunk encapsulation dot1q
 switchport mode trunk
 switchport access vlan 1 -----------------------Default
 switchport voice vlan 31
 no ip address
 mls qos trust cos
 spanning-tree portfast

The spanning-tree port-fast command enabled automatically, I beleive because
of the voice vlan configuration. What I like to know if it is necessary to
configure "Spanning-tree bpduguard" command to put the port in err-disable
mode if someone connects a switch to the other end instead of the host. I
have done that for Data only configuration, but do I need to do that where
both voice/data vlans are configured on the same port, and PC will be
connected to the IP Phone. Please advise.

Can someone help configuring the same commands with CAT-OS as it doesn't
have
a such command "Switchport voice vlan x" instead it requires "Auxilary Port"
command. I did search on CCO, but I am not very clear about it.

Regards,

Richard
