Configuring the Stack Connection Mode

Configuring the Stack Connection Mode

Context

Stack member switches can be connected through MPU or LPU connection mode. The two connection modes differ in locations of stack management links:
  • MPU connection mode: Stack management links are established on SIP ports of MPUs. This mode separates management links from forwarding links to improve system reliability.

  • LPU connection mode: Stack management links are integrated with data forwarding links. This mode does not use SIP ports on MPUs and therefore simplifies network deployment and maintenance.

NOTE:
  • Stack member switches must use the same connection mode. Otherwise, they cannot set up a stack.

  • You are advised to preferentially use the MPU connection mode. This mode separates management links from forwarding links, ensuring high reliability of the stack system.

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 link-type { mainboard-direct | linecard-direct } command to specify the stack connection mode.

    By default, the MPU connection mode is used. After changing the stack connection mode, restart the switch for the configuration to take effect.

    When a switch already has the stacking function enabled, run the stack member { member-id | all } link-type { mainboard-direct | linecard-direct } command to change the stack connection mode of the switch.

  4. Run the commit command to commit the configuration.
