Configuration Examples for Switch Stacks Switch Stack Configuration Scenarios Most of these switch stack configuration scenarios assume that at least two devices are connected through their StackWise ports. Table 2: Configuration Scenarios Managing Switch Stacks Configuration Examples for Switch Stacks Command Description show switch stack-ports [summary] Displays port information for the stack. Use the summary keyword to display the stack cable length, the stack link status, and the loopback status. show switch stack-ports [detail] Displays the stack link status and information for each stack member.
Use the detail keyword to display the stack interface status, errors, drops, packet transmission and bandwidth details. show redundancy Displays the redundant system and the current processor information. The redundant system information includes the system uptime, standby failures, switchover reason, hardware, configured and operating redundancy mode. The current processor information displayed includes the active location, the software state, the uptime in the current state and so on. show redundancy state Displays all the redundancy states of the active and standby devices.
Scenario Result Active switch election specifically determined by existing active switches Connect two powered-on switch stacks through the StackWise ports. Only one of the two active switches becomes the new active switch. Active switch election specifically determined by the stack member priority value 1. Connect two switches through their StackWise ports. 2. Use the switch stack-member-number priority new-priority-number EXEC command to set one stack member with a higher member priority value. 3. Restart both member switches at the same time. The stack member with the higher priority value is elected active switch. Managing Switch Stacks 10
