Stacking
This section describes the basic functions which enable a properly connected set of
switches to function as a single logical entity for management purposes. For
information on how to physically connect units into a stack, see the Hardware
Installation Guide. For detailed information on how stacking is implemented for this
type of switch, refer to “Stack Operations” in the CLI Reference Guide.
Setting the
Master Unit
Use the System > Stacking (Configure Master Button) page to configure a unit as
the stack master.
Command Usage
◆ The switch must be rebooted to activate this command. Note that the
configured setting is not affected by changes to the start-up configuration file.
◆ Set the front panel 10G ports to stacking mode with the Configure Stacking
Button page prior to rebooting the switch.
◆ If the stack has not been initialized, the master button must be disabled on all
other units in the stack, and those units rebooted.
◆ If the stack has been initialized, and this page is used to configure a new stack
master, then the master button on the old master unit must be disabled before
rebooting the stack.
◆ After the newly configured stack master has been rebooted, the front panel
unit identifier will the updated on each unit in the stack.
◆ The bootup messages on all slave units will be halted when the master unit is
rebooted, and configuration through the CLI will be restricted to the master
unit.
Parameters
The following parameters are displayed:
◆ Unit – Shows the stack members according to assigned identifiers.
◆ Master Button – Enables the specified unit as the stack master.
(Default: Disabled)
