Chapter 3: Configuring Stacking Switches | 83
GS752TXS Smart Switch Software Administration Manual
Web GUI, the system applies default settings to all the Stack member units and would reset
the Stack including the participating stack members.
When the stack is powered up and completes the boot process or the original Master Switch
becomes unavailable, the Master Switch is determined through the Master Switch Election
process.
The rules for Master Switch Election are as follows:
• If a unit had previously been elected Master Switch, then it will remain the Master Switch
and other units will simply be Subordinate Switches.
• If no units were Master Switches, or more than one unit was a Master Switch, then the
unit with the highest management preference is elected Master Switch. The management
preference can be assigned by the administrator. However, if all units have the same
management preference, then the unit with the highest MAC address is assigned as the
Master Switch.
Configuration
Stack Configuration
This page moves the Primary Management Unit functionality from one unit to another. Upon
execution, the entire stack (including all interfaces in the stack) is unconfigured and
reconfigured with the configuration on the new Primary Management Unit. After the reload is
complete, all stack management capability must be performed on the new Primary
Management Unit. To preserve the current configuration across a stack move, save the
current configuration to the NVRAM before performing the stack move. A stack move causes
all routes and layer 2 addresses to be lost. The administrator is prompted to confirm the
management move.
To display the Stack Configuration page, click System  Stacking  Basic  Stack
Configuration. A screen similar to the following displays.
