I have a stack containing:
1 3750G (gigabit speed ports)
All are 24 port. The gigabit 3750g is the master. I want to upgrade the IOS to the crypto version: the only IOS image I can find is:
which works fine on the standard 3750s when they are not stacked, however when stacked, the master (the 3750g) takes this image and when loaded as boot image, it complains of incompatible software so I must roll back.
Am I right in configuring a stack with 2 types of switch as this? - if so, how do I upgrade the IOS to the version I want?
