Thank you, native vlan for the trunk ports was the problem.

Hello Experts,<br />
I have the following config on the switchports of a 3550 switch:<br />
<br />
interface FastEthernet0/x<br />
&nbsp;switchport access vlan 3<br />
&nbsp;switchport trunk encapsulation dot1q<br />
&nbsp;switchport mode trunk<br />
&nbsp;switchport voice vlan 2<br />
&nbsp;spanning-tree portfast<br />
<br />
VTP is transparent<br />
VLAN1 is shutdown<br />
VLAN2 is voice<br />
VLAN3 is data<br />
<br />
I am trying to get the port to act like a switchport when a computer is plugged into it and a trunkport when a VoIP phone is plugged into it (non-cisco phone).<br />
<br />
TIA for any and all help!<br />
<br />
Sincerely,<br />
Bob

Does the trunk command negate the switchport access command?

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Switches / Hubs

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
