Dynamic Slot Numbering and
Management Role Assignment
When a stack of OmniSwitch 6800 Series switches boots, the
system software automatically detects the switch in the stack
with the lowest MAC address. This switch is assigned the
primary management role and, by default, is given the slot
number 1. The module connected to the primary’s stacking
port A is automatically assigned the secondary management
role and given the slot number 2.
As the other modules in the stack become operational, they are
assigned idle roles and are automatically assigned unique slot
numbers (3–8, depending on the number of switches in the
stack). The slot numbering for idle modules is determined by
each module’s physical location in the stack.
Note.
As the slot numbers are dynamically assigned,
boot.slot.cfg
files are auto-generated in the /flash direc-
tory of each switch. When the stack is subsequently
booted, each switch reads its slot number assignment from
this file and comes up accordingly.
In the example below, the fourth switch from the top is elected
the primary management module for the stack. (It can be
assumed that this switch has the lowest MAC address in the
stack.) This switch is automatically assigned slot number 1.
The switch immediately below is connected to the primary
switch’s stacking port A and, as a result, is assigned the
secondary management role and given slot number 2.
Slot 1 - Primary
Slot 2 - Secondary
Slot 3 - Idle
Slot 4 - Idle
Slot 5 - Idle
Slot 6 - Idle
Slot 7 - Idle
Slot 8 - Idle
