Note – It is recommended not to disconnect and reconnect the stack links after the stack is formed. If the stack links are disconnected, stack operation can become unstable as the stack reconfigures, and traffic can be disrupted, causing data loss.
7.On the designated Master switch, configure the Master interface for the stack.
>># cfg/stack/mif
>>Master Switch Interface# addr 10.10.1.1
>>Master Switch Interface# mask 255.255.0.0
>>Master Switch Interface# gw 10.10.20.2
Note – The mif menu is available only on the Master switch once the stacking mode has been set (Step 4) and the switch has been rebooted (Step 5).
