Command SWITCHPORT VOICE VLAN

Hi,

I tried to summarize the behavior of the switch depending on the configuration of the command "switchport voice vlan".

The attached file indicates:

- the way the frame is encapsulated: Tagged or Untagged

- if tagged: the VLAN used in the Tag

- for Voice & Data frames

- for frames sent:

     * from IP phone to Access Switch

     * from Access Switch to IP Phone

     * from Access Switch to Distribution Switch

Any comment on this output would be appreciated.

Thanks,

Navid

Here is an updated version again...

Thank you Francisco, this link is the same as the cisco documentation, and does not say much about the "untagged" and "none" cases.
