There are two separate Cat6513 chassis each contain a CSM.We configured as active/standby mode. In future, we will upgrade image of CSM from 4.2(3) to 4.2 (11). After I finish upgrade image and reboot the standby one,
My question is if the A/S mode could be generated because of different image at that time?
Through the CSM configurationguide 4.2 from Cisco website, I found the topic "Configuring a Hitless Upgrade". Another question is when we will reboot the active CSM. Until old standby one is online?
Please advice. Thanks a lot first.
