Planning a Switch Stack
Stack Bandwidth and Partitioning Examples
Figure 2-5 shows a stack that provides full bandwidth with redundant connections.
Figure 2-5 Stack with Full Bandwidth Connections
Figure 2-6 shows a stack with incomplete stack cabling connections. This stack provides only half
bandwidth and does not have redundant connections.
Figure 2-6 Stack with Half Bandwidth Connections
In Figure 2-7 , the stack cable is bad in link B; therefore, this stack provides only half bandwidth and
does not have redundant connections. In Figure 2-8 , link B is bad; therefore, this stack partitions into
two stacks, and switch 1 and switch 3 are stack masters.
