Hi All,
I had a understanding of setting the config register to 0x2102 before IOS upgrade of any router/switches to load the config from NVRAM & IOS from flash during next bootup. This would throw up a prompt under show version as 0x2102 in next reload.
When i followed a same on 3850 stack with setup of 0x2102 switch came up with config which was a success but it always shows up 0x102 under show version output. I have seen this behavior in 2 upgrades of 3850.
This was not seen in other switches like 3750,4500 which shown up correct value 0x2102 after upgrade.
Any idea why is it so with 3850 showing as 0x102? Is that a bug as i am not finding any concrete reason for this on support forums.
Regards,
Vishal
