Poor performance using archive download-sw 3750

[misd.network.support]

Hi,

I have a stack of 4 3750 switches. I wanted to upgrade the IOS and used the "archive download-sw /overwrite /imageonly http://...." command to do so.

After the process had been running a minute or so, I lost a bunch of switches further connected to the stack, and a lot of servers hosted by these switches dropped off the network a few times.

Is this expected behaviour? Is it possible to throttle the CPU usage of the upgrade command.

Cheers,

Ben

Never have heard of being able to do anything like that for a tftp session for downloading code.
