For a parent stack that is split into two child stacks, A and B, each with multiple units:
•
If one of the new stacks receives the master and the standby management units, it is unaffected by the split.
•
If one of the new stacks receives only the master unit, that unit remains the stack manager, and Dell Networking OS elects a new
standby management unit.
•
If one of the new stacks receives only the standby unit, it becomes the master unit of the new stack, and Dell Networking OS elects a
new standby unit.
•
If one of the new stacks receives neither the master nor the standby management unit, the stack is reset so that a new election can
take place.
Stacking Configuration Tasks
Following are the stacking configuration tasks:
•
Assigning Unit Numbers to Units in a Stack
•
Creating a Virtual Stack Unit in a Stack
•
Displaying Information About a Stack
•
Influencing Management Unit Selection on a Stack
•
Managing Redundancy on a Stack
•
•
Assigning Unit Numbers to Units in an Stack
Each unit in the stack has a stack number that is either assigned by you or Dell Networking OS.
Units are numbered from 1 to 6. Stack numbers are stored in NVRAM and are preserved upon reload.
•
Assign a stack-number to a unit.
EXEC Privilege mode
stack-unit
old-unit-number
renumber
new-unit-number
Renumbering the stack manager triggers the whole stack to reload, as shown in the message below. When the stack comes back online,
the master unit remains the management unit.
Dell#stack-unit 2 renumber 1
Renumbering master unit will reload the stack.
WARNING: Interface configuration for current unit will be lost!
Proceed to renumber [confirm yes/no]: yes
Creating a Virtual Stack Unit on a Stack
Use virtual stack units to configure ports on the stack before adding a new unit.
•
Create a virtual stack unit.
