Switch Stack Configuration Files - NETGEAR ProSafe GSM5212P Software Administration Manual

5. Install the new switch in the rack:
• If you are installing the same model switch, put it in the same position in the stack as
the one that you just removed.
• If you are installing a different model switch you can either put it in the same position
as the previous switch, or at the bottom of the stack.
6. Cable the new switch, following the established order of stacking cables.
7. Power up the new switch. Verify, by monitoring the master switch console port, that the new
switch successfully joins the stack by issuing the show switch command. The new switch
should join as a member (never as master; the existing master of the stack should not
change).
8. If the code version of the newly added member is not the same as the existing stack, update
the code as described in

Switch Stack Configuration Files

The configuration files record settings for all global and interface-specific settings that define
the operation of the stack and individual members. Once a save config command is
issued, all stack members store a copy of the configuration settings. If a stack master
becomes unavailable, any stack member assuming the role of stack master will operate from
the saved configuration files.
When a new, out-of-box switch joins a switch stack, it uses the system-level settings of that
switch stack. However, if you want it to store this system level configuration, you must issue a
save config command.
You back up and restore the stack configuration using the copy command the same way that
you would for standalone switch configuration.
The following table provides switch stack configuration scenarios. Most of the scenarios
assume at least two switches are connected through their stacking ports.
Table 1. Switch Stack Master Scenarios
Scenario
Stack master election specifically
determined by existing stack
masters.
Note: This is not recommended.
Stack master election specifically
determined by the stack member
priority value.

Action
Connect two powered-on switch stacks
through the stacking ports.
• Connect two switches through their
stacking ports.
• Use the global configuration
command switch
stack-member-number priority
new-priority-number to set a
stack member to a higher member
priority value.
• Restart both stack members at the
same time.

Result
Only one of the stack masters
becomes the new stack master.
No other stack members become
the stack master.
The stack member with the
higher-priority value is elected
stack master.
