phones getting IP from data VLAN
|
|
| Curt Shaffer 2007-11-24, 7:11 pm |
| I have a series of phones on the network that seem to keep getting an IP
from the data VLAN DHCP server. All of my switch ports are configured the
same. It's just some work and some don't. I have searched docs and the web
about this and found that there are some issues with older firmware but the
thing is that I have phones that did this at first and work fine now and
some phones worked fine at first and now do this. It's really quite odd. Has
anyone seen such an issue or got any advice? I'm not onsite so I can't
easily span the port and grab a capture today. DCHP is coming from the CME
router just FYI.
Here are the specs:
Phone models:
7940 and 7960
Version :
P0030301MFG2
Switch IOS (x2):
Cisco IOS Software, C3560 Software (C3560-IPBASE-M), Version 12.2(35)SE5,
RELEASE SOFTWARE (fc1)
Router IOS:
Cisco IOS Software, 2800 Software (C2800NM-SPSERVICESK9-M), Version
12.4(15)T1,RELEASE SOFTWARE (fc2)
Thanks
Curt

| Yes they are right out of the box. When you are saying put them directly
into the voice vlan you mean only adding switch port voice vlan xx on the
switch port only?

Are these newly deployed phones? There was (and still is likely) an issue
with phones out of the box that need to be put on the voice vlan directly in
order to get the ball rolling. People have said the TAC told them the same
thing.
I ran into this and once the initial upgrade happened, things were fine.

no - add the voice vlan to the port as if it were the data vlan, plug in the
phone, let it do it's thing, then you can resort back to voice/data vlan
config.
or rather than changing ports all over the switch, just bring the phones to
a depot with the right config, let the phones upgrade, then redeploy.

| Make your access and voice vlan the same, so the port is only in one
VLAN until the phone gets updated off the MFG phone load.
Sample:
switchport access vlan 20
switchport mode access
switchport voice vlan 20 (not needed with this temp config)
spanning-tree portfast
After the phone gets upgraded to your phoneload version, you can
revert the switchport config back to normal config.
switchport mode access
switchport access vlan 10
switchport voice vlan 20
spanning-tree portfast
What type of switch are you using?
I had posted about this issue 3-4 weeks again, as this issue has been
around a very long time with phones shipped out with a MFG load on
them. It goes back to the early 3.x days from my experience.

it and let it go for like 15 or 20 minutes. Then check back.

they aren't made by Cisco.
I have never seen this with a Selsius phone.

| If you go the phones web page, you can see if it took a phoneload
update to a newer version.
Or you can look under show cdp details for the switch port the phone
is plugged into, the phoneload version is reported in the CDP
information.
If the phoneload still has a MFG in it, then maybe the CME router is
not serving up the new phoneload via TFTP correctly if one is set.

| I'm being to lazy to read the whole thread, but is your Data Vlan getting DHCP from a Windows 2003 or later server? I just did an install for a school board where half way through they migrated there DHCP service to new servers and the situation you desc
ribed started. We had to make sure the switchport the server was attached to was access mode only and did not have a voice vlan configured. Initially all copper ports were configured for phones. Not all the phones had the problem. About 1/3rd of them w
orked.

no - add the voice vlan to the port as if it were the data vlan, plug in the phone, let it do it's thing, then you can resort back to voice/data vlan config.
or rather than changing ports all over the switch, just bring the phones to a depot with the right config, let the phones upgrade, then redeploy.
your choice.

Are these newly deployed phones? There was (and still is likely) an issue with phones out of the box that need to be put on the voice vlan directly in order to get the ball rolling. People have said the TAC told them the same thing.
I ran into this and once the initial upgrade happened, things were fine.

I have a series of phones on the network that seem to keep getting an IP from the data VLAN DHCP server. All of my switch ports are configured the same. It's just some work and some don't. I have searched docs and the web about this and found that the
re are some issues with older firmware but the thing is that I have phones that did this at first and work fine now and some phones worked fine at first and now do this. It's really quite odd. Has anyone seen such an issue or got any advice? I'm not onsit

| Actually despite all that was mentioned I think this was it. I did a quick
show on all mac addresses, put the mac's from the servers (2 DHCP servers
for data) in the data VLAN only, rebooted the phones and all looks well.
This is very interesting seeing that I had the same config (i.e. switchport
voice VLAN 20) on all of the ports. But in any case it looks good now. And
due to information from another member I have removed trunk settings as
well. This did not cure the issue like the removal of the servers from the
switchport voice vlan but seems to make a cleaner config.
Thanks to all for your help!
Curt
