M4300 Series and M4300-96X Fully Managed Switches Stack Members A switch stack can include up to eight stack members connected through their stack ports. A switch stack always includes one stack master. A standalone switch is a switch stack with one stack member that also operates as the stack master. You can connect one standalone switch to another to create a switch stack containing two stack members, with one of them being the stack master. You can connect standalone switches to an existing switch stack to increase the stack membership. The operation of the switch stack continues uninterrupted during membership changes unless you remove the stack master or you add powered-on standalone switches or switch stacks. Stack Member Numbers A stack member number (1 to 8) identifies each member in the switch stack. The member number also determines the interface-level configuration that a stack member uses. You can display the stack member number by issuing the show switch user EXEC command. A new, out-of-the-box switch (one that did not join a switch stack or was not manually assigned a stack member number) ships with a default stack member number of 1. When the switch joins a switch stack, the default stack member number of the switch changes to the lowest available member number in the stack. Stack members in the same switch stack cannot be assigned the same stack member number. Every stack member, including a standalone switch, retains its member number until you manually change the number or unless the number is already being used by another member in the stack. Fore more information, see Renumber Stack Members on page 466. Stack Member Priority Values You can change a stack member priority. This is useful if you want to change the master of the stack. To change the stack member priority, issue the switch unit priority value command in the global config mode. Install and Power-up a Stack Many switch models include a Hardware Installation Guide with information about rack mounting and stack cabling. Switch Stacks 453 Software Administration Manual
