3750 stacked IOS update

Hi,

Is case, If we update the IOS of 3750 which are stacked together and are accessed by a single management IP address, then are all switches in stack are updated ( falsh ) or we need to update each switch separately.

Any docuemnt on cisco.com?

Thanks

If you use the automatic method then yes you download the software image onto the stack master and it is propogated to the rest of the stack members. However you can also use the manual method which involves updating the IOS on each switch manually. See this doc for full details -
