RHEL 5.6 ethernet question

I installed RHEL 5.6 and configured the network successfully

I could putty in without problem

Then I rebooted and reconfigured the machine to disable hyperthreading.  I made no other system changes.

After RHEL came up, I could not putty in

I went into RHEL from the IMM, and could not start eth2 (the 10GB card).  It said

"eth2 has a different MAX address than expected'

Open in new window


How can I resolve this ?

I understand I have to modify the ifcfg-eth2, what I do not understand is how to find out what the correct MAX address is

I performed a yum update before the reboot, so reading the referenced threads, that is apparently what happened to change the MAX address

However, I can not tell from the referenced note how to find out what the origiinal MAX was.  The ifconfig up eth2 will not work, that will only show the current MAX, not the origianl

How do I find the original MAX
