I am about to replace the supervisor engine in our pair of distribution switches in our data center. We currently have a FWSM module installed in each of my distribution switches running 3.1(20) code. The old sup720 are running 8.6(4) and the mfsc are running 12.2(17d)SXB11a. I am wondering about the compatibility of running the FWSM with the same code after installing the new VS-S720 modules. I do not plan on configuring virtual switch yet and did plan on upgrading the FWSM to 4 code train but just not immediately. Will I be able to run my FWSM using the current 3.1(20) code after I install my new VS-S720 running in native mode?
If I have to upgrade the FWSM then I need to know if I have to upgrade the module in each distribution switch at the same time? Furthermore I do not believe that the FWSM 4 code is supported in hybrid mode, which means that I will have to convert to native before upgrading to FWSM 4 before I install the VS-S720 in one of my distribution switches. Currently the FWSM modules are in active/standby mode in different chassis.
I had planned to install the VS-S720 module in one of my distribution switch and do the other installation a week later. I would rather not have to convert to native and upgrade the FWSM modules in both distribution switches during the first switch upgrade. Please let me know what my options are for this pending maintenance.
