Hai,
Trunking uses certain protocols such as isl or 802.1q for identifying the
vlan information. When the packets are usually passed on to the pc this vlan
information is stripped off.But if you put the pc on a trunk the vlan
informations will be passed on to the pc and it has no means of interpreting
it. So dont put the pc on a trunk link.
