Stacked Device and Version Requirements

Stacked Device and Version Requirements

Licensing Requirements

Stack is a basic feature of a switch and is not under license control.

Device and Version Requirements

Table 1-2 lists the devices models and versions used to set up stacks.

V200R002C50 and later versions

NOTE:
  • Switches of different series cannot set up a stack. That is, a stack cannot be set up between CE12800, CE12800S, and CE12800E.

  • Switches of the same series but different models can set up a stack. For example, a stack can be set up between CE12804 and CE12808, and between CE12804S and CE12808S.

  • The CE12800E does not support the stacking function after FD-X series cards are installed.

Card Requirements

  • MPU: Each member switch needs to have at least one MPU installed regardless of any connection mode. To ensure high reliability, it is recommended that each member switch have two MPUs installed.

    NOTE:

    To set up a stack, two stack members must use MPUs of the same model. Switches using MPUs of different models cannot set up a stack together. For example, a switch using CE-MPUA cannot set up a stack with a switch using CE-MPUB.

  • LPU: Each member switch needs to use at least one LPU to set up a stack. To ensure high reliability, it is recommended that each member switch use two or more LPUs to set up a stack.

    In V200R001C00 and earlier versions and MPU connection mode, if all forwarding links fail and the master switch has working LPUs, all service ports on the standby switch enter the Error-Down state.

    In V200R002C50 and later versions and MPU connection mode, if there is no forwarding link between two member devices, all service ports of one member device enter the Error-Down state.
    • If two member devices are not connected through the forwarding link when setting up a stack or the forwarding link has not been Up after a stack is set up, service ports on the standby switch enter the Error-Down state.
    • If the forwarding link changes from Up to Down, service ports on the member device with fewer LPUs enter the Error-Down state. If the two member devices have the same number of LPUs, service ports on the standby switch enter the Error-Down state.
