Possible Cause
The L2 switch port
for the phone
interface is shut
down or not
configured properly.
Corrective Action
Check the L2 switch and ensure that the port is
1.
not shut down.
For a Cisco L2 switch, ensure that this is a trunk
2.
port with Dot1q encapsulation, and that this
trunk port allows both native and Voice LAN to
pass through.
For an HP L2 switch, ensure that Native Lan is
3.
untagged, and that Voice LAN is tagged.
Verify whether there are two physical interfaces
4.
to the router (one per VLAN), or a router on a
stick configuration (one physical with virtual
sub-interfaces).
Ensure that the ports on both sides (L2 switch
5.
and router) are not shut down (See "Network
Configuration Examples" in the "Typical
Network Configurations" chapter of the Techni-
cian's Handbook).
If there is a physical interface on the router for
6.
each VLAN, make sure that the L2 switch is set
to correctly access port for the corresponding
VLAN/ subnet.
If there is one physical interface on the router
7.
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 sub-interface, ensure that the
8.
proper VLAN is associated to the remote
sub-interface.
