Configuring Ports Excluded from Shutdown When a Stack Has No Forwarding Link

Configuring Ports Excluded from Shutdown When a Stack Has No Forwarding Link

Context

In MPU connection mode, if there is no forwarding link between two member devices, service ports of one member device enter the error-down state.
  • If two member devices are 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.

To retain services on some ports, configure these ports as ports excluded from shutdown. These ports then will not set to error-down state.
NOTE:
  • This function can be configured only when the stack connection mode is MPU connection.

  • Physical member ports cannot be configured as ports excluded from shutdown. Ports excluded from shutdown cannot be configured as physical member ports either.

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 no-stack-link exclude interface interface-type { interface-number1 [ to interface-number2 ] } &<1-32> command to configure ports excluded from shutdown.

    By default, no port is configured as a port excluded from shutdown.

  4. Run the commit command to commit the configuration.
