Probable Causes

does not have enough
IP addresses.
Corrective Action
3.
If there is a physical
interface on the router for
each VLAN, make sure
that the L2 switch is set to
access port for the
corresponding VLAN/
subnet correctly (see
Appendix A on page 215
for more information);
OR
4.
If there is one physical
interface on the router for
multiple VLANs , ensure
that this is a trunk port on
the L2 switch, and ensure
that this trunk port allows
both native and voice lan
to pass through.
On the router
subinterface, ensure
that proper the VLAN
is associated to the
remote subinterface
(see Appendix A on
page 215).
Create a larger scope
with more IP
addresses on the
DHCP server.
