Secondary Management Module Selection
In order to provide effective management module redundancy, all OmniSwitch 6350 stacked
configurations dynamically assign a backup, or secondary, management module during the boot process.
OmniSwitch 6350 stacks use two different methods for selecting the secondary switch.
These methods are:
•
Stacking connection to the primary switch
•
Saved slot number
Using the Stacking Connection to the Primary Switch
By default, the switch that is connected to the primary switch’s stacking port A is automatically assigned
the secondary management role. This applies to stacks on which there is no preassigned slot information—
i.e., there is no
boot.slot.cfg
file present in any switch.
For more information on using the stacking connection to the primary switch to determine the secondary
management module, refer to the diagram below:

Note.
For information on dynamic slot numbering for idle elements within the stack, refer to
Four OmniSwitch 6350 switches are stacked
and connected via stacking cables, as shown.
All switches are currently powered off. None
of the switches have preassigned slot num-
bers—i.e., there are no boot.slot.cfg files pres-
ent. The user powers on all switches in the
stack in close succession and the stack begins
the boot process.
By default, the switch connected to
the primary’s stacking port A is
automatically assigned the second-
ary management role. The second-
ary switch is dynamically assigned
slot number 2.

When the elements in the stack come
online, the switch with the lowest
MAC address is given the primary
management role and is dynamically
assigned slot number 1.
