The switch with the highest priority number is elected Master. The switch with the
next highest priority number is elected Standby Master and takes over stack
management if the Master Switch fails. For example:

Managing a Stack
Master and Member Switches
You can manage a stack of MXL 10/40GbE Switches as a single entity when
connected together. Manage the stack from the CLI through the serial
console connection or a remote Telnet session over the OOB management IP
address.
When you create a stack is created, one switch automatically becomes the
Master Switch and another switch is elected Standby Master. The Master
Switch maintains stack operation with minimal impact in the event of:
•
Switch failure
•
Inter-switch stacking link failure
•
Switch insertion
•
Switch removal
If the Master Switch goes off line, the Standby Master replaces it as the new
master and the switch with the next highest MAC address or priority becomes
Standby Master.
Stack Startup
Topology Discovery
When a stack is formed, a topology discovery process builds up a database
that contains information about all of the switches in the stack, including the
Dell Networking OS version, hardware version, management priority, and
switch MAC address. To view this information, use the show system
command.
