Stacking Configuration Tasks; Assigning Unit Numbers To Units In An Stack; Creating A Virtual Stack Unit On A Stack - Dell S3048-ON Configuration Manual

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.

Following are the stacking configuration tasks:
• Assigning Unit Numbers to Units in a Stack

• Displaying Information About a Stack
• Influencing Management Unit Selection on a Stack
• Managing Redundancy on a Stack
• Resetting a Unit 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
