Resilient IP Interface for Management Access

The stack functions as one integral system for management and
configuration purposes. You can therefore manage the stack through any
IP interface configured on the stack. The Master unit does not even have
to include an active port member in the VLAN interface used for
management access. However, if the unit to which you normally connect
for management access fails, and there are no active port members on the
other units within this VLAN interface, then this IP address will no longer
be available. To retain a constant IP address for management access across
fail over events, you should include port members on several units within
the primary VLAN used for stack management.

Resilient Configuration

If a unit in the stack fails, the unit numbers will not change. This means
that when you replace a unit in the stack, the original configuration for the
failed unit will be restored to the replacement unit. This applies to both the
Master and Slave units.

Renumbering the Stack

The startup configuration file maps configuration settings to each switch
in the stack based on the unit identification number. If the units are no
longer numbered sequentially after several topology changes or failures,
you can reset the unit numbers using the "Renumbering" command in the
web interface or CLI. Just remember to save the new configuration settings
to a startup configuration file prior to powering off the stack Master.

Ensuring Consistent Code is Used Across the Stack

Consistent Runtime Code in Each Switch – The main board runtime
firmware version for each unit in the stack must be the same as the Master
unit's runtime firmware. After Auto-ID assignment is completed, the
Master unit checks the image versions for consistency. If the firmware
versions (i.e., runtime code) configured for bootup on any slave units are
