[CLUE-Tech] What is 802.1q from cisco?

[black at galaxy.silvren.com]

To clarify a little (sorry if this seems pedantic) trunking is a way to
carry multiple VLAN traffic over a single link. Normally a port is only a
member of one VLAN, but if you have an uplink to a switch for example that
needs to carry traffic for several VLANs, trunking is the way to
accomplish this.
