Configuring a Stack Member ID

Configuring a Stack Member ID

Context

Stack member IDs are used to identify and manage member switches in a stack. Each member switch has a unique stack member ID.

If stack member IDs conflict in a stack, the master switch assigns new stack member IDs to member switches. That is, the master switch checks stack member IDs in ascending order (from 1 to the largest stack member ID) to find an unused stack member ID and then assigns the found stack member ID to the member switch with a conflicting stack member ID.

Procedure

  1. Run the system-view command to enter the system view.
  2. Run the stack command to enter the stack management view.
  3. Run the stack member member-id renumber new-member-id [ inherit-config ] command to configure a stack member ID for the local switch.

    By default, the stack member ID of a switch is 1. After changing the stack member ID, restart the switch for the configuration to take effect.

    If you specify inherit-config, the switch inherits the original stack configuration after it restarts, including the stack priority, stack domain ID, and physical member port configuration.

    If you do not specify inherit-config, the current stack configuration is lost after the switch restarts, and the configuration related to the new stack member ID in the configuration file takes effect.

    For example, if a switch uses a stack member ID 1 and has the following stack priority configuration:
    #
    stack member 1 priority 150
    #
    If inherit-config is specified when the stack member ID is changed to 2, member ID 2 will inherit the stack priority configuration of member ID 1 after the switch restarts. For example:
    #
    stack member 1 priority 150      // Configuration of member ID 1 becomes the offline configuration.
    #
    stack member 2 priority 150      // Member ID 2 inherits the stack priority configuration of member ID 1.
    #
    If inherit-config is not specified, member ID 2 will not inherit the stack priority configuration of member ID 1 after the switch restarts. For example:
    #
    stack member 1 priority 150      // Configuration of member ID 1 becomes the offline configuration, and configuration of member ID 2 is empty.
    #
    If the switch already has offline configuration of member ID 2 before restarting, for example:
    #
    stack member 1 priority 150
    #
    stack member 2 priority 200      // The switch already has offline configuration of member ID 2 before restarting
    #
    When the stack member ID is changed to 2, inherit-config cannot be specified. The switch will use the configuration of member ID 2 in the configuration file after restarting. For example,
    #
    stack member 1 priority 150      // Configuration of member ID 1 becomes the offline configuration
    #
    stack member 2 priority 200      // Configuration of member ID 2 in the configuration file takes effect.
    #
    NOTE:
    • If the configuration file contains offline configuration for the new stack member ID, do not specify inherit-config in the command.

    • Common service port configurations, for example, port split configuration, will be lost after the stack member ID is changed and the switch restarts.

  4. Run the commit command to commit the configuration.
