Auto Stack ID Assignment
During the stack formation process, every switch is assigned a Stack ID. Once Stack ID assignment
is complete, each switch saves its Stack ID into the nonvolatile FLASH memory. You can use
the CLI or the Web interface to view the stack IDs.
Firmware Version Checking
Following Stack ID assignment, the Master Switch performs a consistency check to make sure
that all switches in the stack are running the same firmware version.
If the switch software versions do not match, then the ports on the member switch will not become
valid for operation. This condition is known as the Suspended Stacking Mode. You can then
synchronize the firmware on the member switch with the firmware that is running on the Master
Switch.
System Initialization
If the Master Switch determines during the firmware version consistency check that all switches are
running the same version of firmware, the switch will be initialized for Stacking Mode.
System Initialization for Normal Stacking Mode
The Master Switch will initialize the stack using the last saved system configuration file. For those
switches that do not have a configuration file, the system will apply default settings to those
switches.
If the configuration file is corrupted, the Master Switch will initialize the stack and set it to the
Factory Default Configuration.
You can save the configuration file. The Master Switch automatically distributes the configuration
file to the member switches. If the Master Switch later becomes unavailable, a Member Switch
becomes the new Master Switch and configures the stack with the latest configuration
synchronized from the Master Switch.
System Initialization for Suspended Stacking Mode
After system initialization is complete, the Master Switch will enter Suspended Stacking Mode
if the firmware versions of the stack are inconsistent. In this mode, only the Master Switch is
initialized with configuration file information. None of the member switches are initialized.
This forces all member switches to remain in non-operational mode.
NOTE:
All ports disabled by default.
