Basic Concepts

Basic Concepts

Stack technology involves the following key concepts:

  • Role

    Switches that have joined a stack are member switches. Each member switch in a stack plays one of the following roles:
    • Master switch

      The master switch manages the entire stack. A stack has only one master switch.

    • Standby switch

      The standby switch is the backup of the master switch. When the master switch fails, the standby switch takes over all services from the master switch. A stack has only one standby switch.

    • Slave switch

      A slave switch forwards service traffic. The more slave switches in a stack, the higher forwarding performance the stack can provide. Apart from the master and standby switches, all the other switches in a stack are slave switches.

  • Stack ID

    The stack ID of a member switch is the slot ID of the member switch within the logical switch. Each member switch in a stack must have a unique stack ID.

  • Stack priority

    The stack priority of a member switch determines the role of the member switch in role election. A larger value indicates a higher priority and higher probability that the member switch will be elected as the master switch.
