Understanding Virtual Chassis Roles in an EX8200 Virtual Chassis
The roles of Virtual Chassis members in an EX8200 Virtual Chassis are defined by uptime and hardware type. The XRE200 External Routing Engine with the most uptime assumes the primary role; the external Routing Engine with less uptime assumes the backup role. EX8200 member switches are always in the linecard role.
Table 1 provides a summary of the EX8200 Virtual Chassis roles.
