254 Stacking
Dell EMC Networking N1100-ON and N1500 Series switches do not stack
with different Dell EMC Networking Series switches or other Dell EMC
Networking switches. Dell EMC Networking N1124T-ON/N1148T-
ON/N1124P-ON/N1148P-ON Series switches only stack with other Dell EMC
Networking N1124T-ON/N1148T-ON/N1124P-ON/N1148P-ON Series
switches. Dell EMC Networking N1108T-ON/N1108P-ON switches do not
stack. Dell EMC Networking N1500 Series switches only stack with other
Dell EMC Networking N1500 Series switches.
Dell EMC Networking N2000 Series switches stack with Dell EMC
Networking N2100 Series switches up to eight units. Dell EMC Networking
N3100-ON Series switches stack with Dell EMC Networking N3000E-ON
switches up to twelve units. Dell EMC Networking N2200-ON switches stack
with other N2200-ON switches. Dell EMC Networking N3200-ON switches
stack with other stacking-capable N3200-ON switches up to twelve units.
How is the Stack Master Selected?
A stack master is elected or re-elected based on the following considerations,
in order:
1
The switch is currently the stack master.
2
The switch has the higher MAC address.
3
A unit is selected as standby by the administrator, and a fail over action is
manually initiated or occurs due to stack master failure.
In most cases, a switch that is added to an existing stack will become a stack
member, and not the stack master. When a switch is added to the stack, one
of the following scenarios takes place regarding the management status of the
new switch:
If the switch has the stack master function enabled but another stack
master is already active, then the switch changes its configured stack
master value to disabled.
If the stack master function is unassigned and there is another stack
master in the system then the switch changes its configured stack master
value to disabled.
If the stack master function is enabled or unassigned and there is no other
stack master in the system, then the switch becomes stack master.
