changing vlan setting on 4620 handsets 1

[IPOnewboy]

Hi Hope you can help ??
How do i set up the 4620 handset to permantly search for vlan 2 instead of 0
problem being ,when network goes down,we have a power outage or we do an immeadiate load of config the phones all start search for their DHCP server on Vlan 0

so as a consequence we have to reboot phone and then hit the * key and manually set it to vlan 2

BIT of a pain to do 141 of them !!!!

we are running an IP Office 412 manager version 2.1 (27) as advised by Avaya

Regards

Add an L2QVLAN = 2 entry in the 46xxsettings.txt file located in the Manager folder and then reboot the IP phones. That should do it. I think. Hope that helps.

Staticall addressed phones shouldn't be lossing settinsg when rebooted but thats a separate issue.

You need to setup a 46xxsettings.txt file with a line like:

SET L2QVLAN 2

or add it to the existing file if you already have one.


Put the file in the same location as the 46xxupgrades.scr file. Leave Manager running to act as TFTP server and reboot the phones (x 141 - sorry) (where's the remote reboot command when you need it).

Similar to the static settings, the phone should remember its previous used settings if it reboots and timesout on finding the file again.

have done this ,but the phone does not even get to the stage where it downloads the 46xxsettings.txt file as it seems to be constantly trying vlan 0

hmmm, challenging - if only on how to recreate it in order to test any fix to it.

I don't want to say RTM but the 4600 LAN Administrators Guide may hold some clues. Its written from the Definity/MV/ACM perspective but much is still applicable to IPO. Need to dig around support.avaya.com.

I've pasted the section below. It talks mainly about a VLANTEST parameter (default 60 seconds) that define how long a rebooting phone should wait for DHCPOffer when using a VLAN other than zero - at which point it defaults to zero.



4600 Series IP Telephone Release 2.1 LAN Administrator’s Guide 65
July 2004
If your LAN environment does not include Virtual LANs (VLANs), ignore this section. Otherwise, this
section contains information on how to administer 4600 Series IP Telephones to minimize registration
time and maximize performance in a VLAN environment.
The system value L2QVLAN (initially set to “0”), identifies the 802.1Q VLAN IDentifier. This default
value indicates “priority tagging” as defined in IEEE 802.IQ Section 9.3.2.3, which specifies that the
Ethernet switch in your network closet should automatically insert the default VLAN for the switch port
without changing the user priority of the frame (cf. IEEE 802.1D and 802.1Q).
However, you might not want the default VLAN to be used for voice traffic; for example, you may have
administered a VLAN specifically for IP telephony. In this case, you need to ensure the switch is
configured to allow frames tagged by the 4600 Series IP Telephone through without overwriting or
removing them. In addition, you will want to set the system value L2QVLAN to the VLAN ID
appropriate for your voice LAN.
Another system value you can administer as of Release 1.8 software, is VLANTEST, which stands for
the number of seconds the 4600 IP Series Telephone waits for a DHCPOFFER message when using a
non-zero VLAN ID (the default is “60” seconds). Using this value insures the telephone can return to the
default VLAN if an invalid VLAN ID is administered or if the phone is moved to a port where the value
in L2QVLAN is invalid. The default value is fairly long, to allow for the scenario that a major power
interruption is causing the 4600 Series IP Telephones to restart, but time should be allowed for network
Server Administration
Administering Options for the 4600 Series IP Telephones
routers, the DHCP/TFTP Servers, etc. to be returned to service. If the telephone is restarted for whatever
reason and the VLANTEST time limit expires, the telephone assumes the administered VLAN ID is
invalid and re-initiates registration with the default VLAN ID.
Setting VLANTEST to “0” has the special meaning of telling the phone to attempt DHCP using a nonzero
VLAN, indefinitely. In other words, the telephone will not return to the default VLAN.
NOTE:
If the telephone has returned to the default VLAN but must be put back on the L2QVLAN
VLAN ID, you need to Reset the telephone according to the procedure in Chapter 3 of the
4600 Series IP Telephone Installation Guide.
The telephone will ignore any VLAN ID administered on the media server if a non-zero
VLAN ID is administered manually, via DHCP, and/or via TFTP.

reply to sizbut

i actually downloaded the Lan Admin manual re your earlier reply and found the info about the VLANTEST=0
This was on the Morning of system go live day !!!!
so i avoided the problem of 141 unhappy people
Thanks For pointing me in the right direction,Definately saved my bacon

Remote Reboot of IP Phone
Disconnecting the switch that the IPOhones are connected to from the IPO (or powering it down) will cause all the conected phones to reboot.


Universal Plan "B": when all else fails CHEAT!
