Stack pre-provisiong supported in AOS version 7.1.3 and later, allows user to configure the role and member-id of the members. The members are configured using the Serial Numbers, which could be located at the back of the switch. The cli command
“show stacking members” command also display the serial number.
Once configured the two Primary-Capable switches elect one member as a Primary and Secondary among themselves using the Stacking Primary-Election algorithm. If the Primary unit is away, the Secondary takes over as Primary. No secondary member is elected in this scenario. Members configured as Primary-Capable are part of the election process. Line-card members do not take part in the election process and maintain their role.
When Moving from a dynamic stack configuration to preset stack or vice versa, User has to delete the existing configuration under stack-profile The members go through a reset process. Reboot is not required.
Two members must be configured as Primary-Capable and rest of the members as line-card.
