“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.
