I have a stack of 2 x 3750G-12S-S. Is it possible to upgrade the stack to EMI version (SP Services) ? If yes what is the product reference in Cisco list ?
And another question, if I have a stack with 2 x 3750G-12S-S and I stack one other 3750 with EMI version. Is the stack capable to use the dynamic routing (EMI version) or does I need to have my 3 switches in EMI version ?
Thanks a lot for your help !
Product Number for EMI upgrade is CD-3750G-EMI=
If you make the master of the stack the switch with the EMI image, the entire stack is capable of EMI features. If that switch fails and a non-EMI switch assumes master, it will lose all the EMI features. It's best to upgrade all switches in the stack to EMI.
Hope that helps.
