Renumbering a Stack Unit To renumber a stack unit to reset the unit numbering for a master, standby or member unit, enter the stack-unit renumber command in EXEC Privilege mode and reload the switch. Task Assign a stack-number to a unit. Command Syntax stack-unit unit-number renumber new-number Command Mode EXEC Privilege • If you renumber the master switch, you are prompted to reload the entire stack. • If you renumber the standby switch, only the switch reloads and is replaced by a member switch that is elected as the new standby. • If you renumber a member switch, only the member switch reloads. • If you renumber a switch to a number already assigned to another stack unit, the following error message is displayed: Figure 31-6. Example FTOS#stack-unit 5 renumber 0 % ERROR: stack unit 0 already exists. Provisioning a Stack Unit You can logically provision a stack-unit number to accept only an MXL 10/40GbE Switch. Provisioning is a type of pre-configuration that is stored on the master switch and applied when a stacked unit is assigned the unit number. When you provision a unit number for an MXL 10/40GbE Switch: • The base-module ports on the switch (ports 33 and 37/stack groups 0 and 1) are pre-configured for 40GbE operation. • The 40GbE ports on FlexIO modules (ports 41 and 45 in slot 0; ports 49 and 53 in slot 1) are pre-configured for 4x10GbE (quad mode) operation. To provision a stack unit, use the stack-unit provision command in Global Configuration mode, save the provisioning configuration, and reload the stack. To provision a stack unit, use the following command: Task Create a virtual stack unit by logically provisioning a switch.
