Traditional stack unit identification

Stack units are identified by numbers 1 though 12 on ICX 7250, ICX 7450, and ICX 7750 devices (1 through 8 on some legacy devices). You can display stack unit IDs by entering the show stack command.

A new device (one that has not been connected in a traditional stack or that has not been manually assigned a stack unit number) ships with a default number of 1. Once you enable stacking and the unit becomes part of a traditional stack, its default stack unit number changes to the lowest available number in the stack. You can configure the stack suggested-id command in a standalone unit before it joins a stack to assign this unit the suggested ID.

Stack units must each have a unique identification number. Every stack member, including any standalone units, retains its stack unit number unless that number is already being used in the stack, or until you manually renumber the unit using secure-setup. For more information about how to renumber stack IDs using secure-setup, refer to Renumbering stack units.
