interface is shut down

it is a router on a stick

information).
2.
Ensure the port(s) on
both sides (Layer 2
switch and router) are not
shut down.
3.
If there is physical
interface on the router for
each VLAN, make sure
that the Layer 2 switch is
set to access port for the
corresponding
VLAN/subnet correctly;
