(Remote IP phone
(statically

address) cannot
access MN3300
across WAN).
Problems (continued)
Probable Causes
The PC behind the IP
Phone is changing
speed 100/10.
IP phone fails to
receive Keepalive
message in
30 seconds.
There is electrical
interference.
The Layer 2 switch
port for the phone
interface is shut down
or not configured
properly.
Troubleshooting
Corrective Action
Depending on the
NIC, you may need to
hardcode to 100 MB
instead of auto
negotiation.
Verify if the network or
the Controller is down.
Verify the power
source, and change
the location of the
power source.
1.
Check The Layer 2
switch and ensure that
the port is not shut down
(see Appendix A on page
215 for more
information).
2.
For a Cisco Layer 2
switch: verify that this is a
trunk port with Dot1q
encapsulation, and
ensure this trunk port
allows both native and
voice lan to pass through.
3.
For an HP Layer 2
switch: verify that Native
Lan is untagged and
Voice Lan is tagged.
