Troubleshooting a strictly provisioned, mismatched type

Cause

When the MAC address matches a strictly provisioned configuration, it either matches the configured type and succeeds, or it does not match the type and fails. This is because the MAC address is unique and you cannot have duplicate MAC addresses.

The log messages indicate that this was the type of failure. The information in the log message helps you correct the configuration.

Action
  1. The switch that fails to join automatically reboots. Execute the show stacking command to view the mis-configured entry.

    Displaying the mis-configured entry

    switch(config)# show stacking

    The configuration entry for member 4 matches a J9726A switch that will be added, however, it will fail because it is configured as a J9728A switch.

  2. The following example shows the log entries with the failure to join the stack.
    Log entries displaying stacking failures
    W 10/06/00 03:24:37 03255 stacking: ST2-STBY: Provisioned switch with Member ID 4 
      removed due to loss of communication
    I 10/06/00 03:24:37 02558 chassis: ST2-STBY: Stack port 4 is now on-line.
    I 10/06/00 03:24:35 02558 chassis: ST4-MMBR: Stack port 2 is now on-line.
    W 10/06/00 03:24:35 03274 stacking: ST1-CMDR: Member 4 (1cc1de-4da900) 
      cannot join stack due to incorrect product id: J9278A

    You cannot retype the configuration command with the same MAC address, member ID, and a different J-number. You must remove the configuration and then reconfigure this switch member entry.

  3. Removing a stack member and reconfiguring
    switch(config)# stacking member 5 remove
    
    The specified stack member configuration will be erased. The
    resulting configuration will be saved. Continue [y/n]? Y
    
    switch(config)#: stacking member 5 type J9726A mac 1cc1de-4da900
    This will save the current configuration. Continue [y/n]? Y

  4. Boot the switch with the matching MAC/Type.
