Stack Configuration Cannot Be Edited; Configuring A Stack With A Specific Member Switch As The Master Switch - Alaxala AX6700S series Troubleshooting Manual

3. Troubleshooting Functional Failures During Operation

3.4.2 Stack configuration cannot be edited

If you can make a stack configuration but cannot edit the configuration, check the software
information.
Execute
remote command all show version
information of all member switches in the stack configuration. Even if you already have a stack
configuration, the following software information must be consistent before you can edit the
configuration:
• Software type (OS-L3SA-A/OS-L3SA or OS-L3SL-A/OS-L3SL)
• Software version
If the above are not consistent, make sure that the software information is consistent for all member
switches in the stack configuration.

3.4.3 Configuring a stack with a specific member switch as the master switch

Even if you set a high master selection priority for a member switch you want to make the master
switch, and start (or restart) all the member switches in the stack configuration simultaneously, a
member switch with a high master selection priority might not become the master switch. This is
because the time taken to start up can change due to the following causes, upsetting the
synchronization of the startup of member switches:
• The switch is being restarted
• The software type or software version is different
• The startup configuration is different
• The software was updated or upgraded before startup
If you want to the member switch that becomes the master switch to be fixed, configure the stack
by using either of the following methods:
• Start up the member switch that you want to make the master switch first. After confirming
that this member switch has started and become the master switch, start the remaining
member switches.
• Set a value of
make the master switch, and set
switches. Afterward, start all the member switches.
