These carry the traffic of multiple VLANs--from 1 to 1005 at a time. You
can't run them on 10Mbps links.
same time. This can be a real advantage. For instance, you can actually set
things up to have a server in two broadcast domains simultaneously, so
that your users won't have to cross a layer-3 device (router) to log in and
access it. Another benefit to trunking is when you're connecting switches.
Trunk links can carry some or all VLAN information across the link, but
if the links between your switches aren't trunked, only VLAN 1 informa-
tion will be switched across the link by default. This is why all VLANs are
configured on a trunked link unless cleared by an administrator by hand.
Both switches can communicate to all VLANs because of the trunk link
between them. And remember, using an access link only allows one
VLAN to be used between switches. As you can see, these hosts are using
access links to connect to the switch, so that means they're communicat-
ing in one VLAN only.
