With Cisco phones and switches, what is the proper way to set up the switch to allow a PC and phone at the same time, so that both the PC and phone work?

With Cisco phones and switches, what is the proper way to set up the switch to allow a PC and phone at the same time, so that both the PC and phone work?

• switchport access vlan #, switchport voice vlan #
• switchport access voice vlan #
• This is not possible
• Use the HTTP webUI to configure the switches 

EXPLANATION

Switchport mode access
switchport access vlan (data)
switchport voice (voice vlan)
spanning-tree portfast

CDP will figure out if it is a phone or not and allow clients plugged in behind the phone (through the phone) to use the data vlan


The switch uses CDP to identify the other device as a ip phone and will automatically place that traffic on the voice vlan.  If this is not a Cisco phone you will have hardcode the phone to tag its traffic as vlan x.
