ProSafe M4100 and M7100 Managed Switches The following table provides switch stack configuration scenarios. Most of the scenarios assume at least two switches are connected through their stacking ports. Table 1. Switch Stack Master Scenarios Scenario Action Result Stack master election specifically determined by existing stack masters. Note: This is not recommended. Connect two powered-on switch stacks through the stacking ports. Only one of the stack masters becomes the new stack master. No other stack members become the stack master. Stack master election specifically determined by the stack member priority value. • Connect two switches through their stacking ports. • Use the global configuration command switch stack-member-number priority new-priority-number to set a stack member to a higher member priority value. • Restart both stack members at the same time. The stack member with the higher-priority value is elected stack master. Stack master election specifically determined by the MAC address. Assuming that both stack members have the same priority value and firmware image, restart both stack members at the same time. The stack member with the higher MAC address is elected stack master. Add a stack member. • Power off the new switch • Through their stacking ports, connect the new switch to a powered-on switch stack. • Power on the new switch. The stack master is retained. The new switch is added to the switch stack. Stack master failure. Remove (or power off) the stack master. One of the remaining stack members becomes the new stack master. All other members in the stack remain stack members and do not reboot. Preconfigure a Switch You can preconfigure (supply a configuration to) a new switch before it joins the switch stack. You can specify the stack member number, the switch type, and the interfaces associated with a switch that is not currently part of the stack. Note: If you are replacing a switch with the same model in the same position in the stack, you do not need to preconfigure it. The new switch assumes the same configuration as the previous switch. 364 | Chapter 19. Switch Stacks
