1. Check the Layer 2 switch and ensure that
the port is not shut down (see “Network
Configuration Examples” on page 317 for
more information).
2. For a Cisco Layer 2 switch: verify that this

Native Lan is untagged and Voice Lan is
tagged.

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 the port for the
corresponding VLAN/subnet correctly;
OR
If this is a router on a switch, verify that
this is a trunk port on L2 switch, and
ensure this trunk port allows both native
and voice LAN to pass through.
4. On the router's subinterface, verify that
the proper VLAN is associated to the
subinterface (see “Network Configuration
Examples” on page 317).
