Hi,<br><br>I prefer the second option, it's more explicit, indeed How can one single cable carry Data VLAN and Voice VLAN if there isn't a trunk? in this way 802.1Q / 802.1p is clear. <br><br>see: <a href="http://www.javvin.com/protocol8021P.html">

<p>Hello,</p>
<p>I have always configured the switch IOS ports where IP phones are connected
this way:</p>
<p>int fa0/1</p>
<p>switchport access vlan DATA</p>
<p>switchport voice vlan VOICE</p>
<p>switchport mode access</p>
<p>spanning-tree portfast</p>
<p> </p>
<p>But I've seen in the CCVP courses that the configuration is
different:</p><font face="Helv" size="2">
<p>interface fastethernet 0/1</p>
<p>switchport trunk encapsulation dot1q</p>
<p>switchport trunk native vlan DATA</p>
<p>switchport mode trunk</p>
<p>switchport voice vlan VOICE</p>
<p>spanning-tree portfast</p>
<p>Can anybody explain me the differences between them and if any of them
have any advantage respect the other one? I prefer the first one rather than the
second, I don't like to configure a trunk to connect a phone, but I want to
understand why Cisco recommends the second configuration respect the first
one?</p>
<p>Thanks in advance,</p>
<p>Ruben</p></font></div>
