Comment 3 Elliot Lee 2002-06-21 11:40:39 EDT
Someone with one of these phones will need to do the testing & fixing.

Comment 5 shanes sullivan 2002-06-24 18:17:30 EDT
This bug is listed incorrectly. It is not a Cisco issue. The issue was 
discovered using an Avaya VoIP phone. However it is not a phone issue, it is a 
pxelinux issue. We have done some more testing of this issue in our lab and 
determined that the problem arises when the host running the pxe daemon 
receives is on the same subnet as the ip phone and the dhcp server. you can use 
this link to download a utility that exactly mimics the Avaya IP Phone boot 
process. http://support.avaya.com/BootTest/ 

We have another doc that we have created on this issue that will explain our 
findings further.

While this is indeed not a phone issue, this is also not a PXELinux issue.  
The issue is with the PXE Daemon.  PXELinux is not even being used at the time 
when the problem happens.  The PXE Daemon is seg-faulting when it doesn't 
understand the PXE Packets.
Comment 7 Elliot Lee 2002-07-11 15:59:34 EDT
BootTest is what I'm looking for, except for the fact that it is a Windows program (and won't 
run under wine for want of iphlpapi.dll). If someone wants to write a tiny UNIX program to 
do the equivalent, that'd be much more useful.

Required DLL, put in \windows\system32
Comment 9 Norm Murray 2002-07-24 15:22:12 EDT
Also apparently needed is MPRAPI.DLL

Can someone test this under wine to let us know if this is possible to get
working, and ideally if the BootTest will indeed be sufficient to reproduce the
crash of the pxeserver?
Comment 10 Elliot Lee 2002-07-29 17:32:25 EDT
Errata probably necessary, *sigh*
Comment 11 Elliot Lee 2002-08-08 13:15:19 EDT
The errata is in the queue, I'll pretend I don't have to do anything more on this issue.
Comment 12 Elliot Lee 2002-08-30 09:16:47 EDT
An errata has been issued which should help the problem described in this bug report. 
This report is therefore being closed with a resolution of ERRATA. For more information
