ProSafe M5300 Switch Stack Master Election All stack members are eligible stack masters. If the stack master becomes unavailable, the remaining stack members participate in electing a new stack master from among themselves. The following factors determine which switch is elected the stack master: • The switch that is master always has priority to retain the role of master • Assigned priority • MAC address When the stack is powered up and completes the boot process or the original stack master becomes unavailable, the stack master is determined through an election process. The rules for stack master Election are as follows: • If a unit had previously been elected stack master, then it will remain the stack master and other units will simply be stack members. • If no units were stack masters, or more than one unit was a stack master, then the unit with the highest management preference is elected stack master. The management preference can be assigned by the administrator. However, if all units have the same management preference, then the unit with the highest MAC address is assigned as the stack master. Factory Defaults Reset Behavior If the stack master is reset to the factory default settings (see Factory Default on page 281), the stack master applies the default settings to all the stack members and resets the stack, including all participating stack members. When the stack boots, the stack master election process begins. A switch can be described in terms of three semi-independent functions called the forwarding plane, the control plane, and the management plane. The forwarding plane forwards data packets. The forwarding plane is implemented in hardware. The control plane is the set of protocols that determine how the forwarding plane should forward packets, deciding which data packets are allowed to be forwarded and where they should go. Application software on the management unit acts as the control plane. The management plane is application software running on the management unit that provides interfaces allowing a network administrator to configure and monitor the device.
