Figure 12 shows a stack without redundant connections. When the FlexStack link indicated by B breaks, the
FlexStack will break into two logical switches. The top two members will form one logical stack with two members,
and the other logical stack will contain a single member.
Figure 12. Broken Stack
Since the stack in the connection in Figure 12 has broken into two, only two members will have their stack port
status shown. The third member has been removed from the stack.
Stack port connections for the broken stack shown in Figure 12:
