The page includes the following fields:
Object Description
Specifies the type of topology for the stack: 
Stack Topology
Chain : A chain of switches, that is, no redundant forwarding paths.
Ring : A ring of switches, thereby providing redundant forwarding paths.
Back-to-Back : Two switches interconnected on both stacking ports.

Stack Member Count The number of switches in the stack.

Last Topology Change The time of the last topology change in the stack.
The MAC address of the current stack master switch. 
Master Switch
The time of the last master change in the stack. 
Last Master Change
 Stack List
For each switch in the stack, the following information is shown: The MAC address, Switch ID, product name and version,
and master election state. The master election state is normally "No". Only when a forced master election is enforced by the
user, the master election state takes the value "Yes". For details about the master election algorithm, see Stack Configuration.
The Stack List screen in Figure 4-19-8 appears.
