C9000 Series Syntax Parameters stack-unit unit-number {type unit-type | priority value} To de-provision or delete a port extender stack unit, use the no stack-unit unit-number {type unit-type | priority value} command. stack-unit unitnumber type PE-type priority value Enter the stack-unit ID number to locate a specific stack unit. Stack unit number range is 0-7. Enter a value for the stack-unit type. Enter the master priority value for the unit. The priority value range is from 1 to 14. The unit with the numerically highest priority value is elected the master. Default None Command Modes PE CONFIG Command History This guide is platform-specific. For command information about other platforms, see the relevant Dell Networking OS Command-Line Reference Guide. The following is a list of the Dell Networking OS version history for this command. Version Description 9.11(0.0) 9.9(0.0) Introduced the port extender types for the N20xx and N30xx series. Introduced on the C9010. Usage Information You can pre-provision a port extender stack unit using the stack unit command in the PE configuration mode and specify the stack-unit type. Only similar types of stack units are provisioned under a single port extender. The maximum number of stack units allowed for provisioning is 8. In a PE stack, by default, the stack unit with the highest MAC address is elected master; the stack unit with the second highest MAC address is elected standby. To change the default master and standby assignment, you can assign stack-unitpriority value. If multiple units tie for the highest priority, the unit with the highest MAC address is elected master. In the following example, stack-unit 0 with priority 14 is the master and stack-unit 1 with priority 13 is the standby. NOTE: You can configure a stack-unit priority only when the unit is online. Example (stackunit priority) Dell(conf)#pe 2 Dell(conf-pe-2)#stack-unit 0 priority 14 Dell(conf-pe-2)#stack-unit 1 priority 13 Example (stack unit type) Dell(conf-pe-201)#stack-unit 1 type ?
