Renumbering stack units

Renumbering a Master, Standby or member unit, requires the stack-unit renumber command and a
reload of one or more switches:



Renumbering the Master switch requires a reload of the entire stack



Renumbering the Standby switch only requires that switch to reload, but a different member
switch is elected as the new Standby



Renumbering a member switch requires a reload of that switch only



Renumbering any unit in the middle of a daisy-chain topology stack may require a stack-split
and subsequent stack-merge to occur



Renumbering a switch to a number already assigned to another stack unit results in following
error message:

“Renumbering will reset the unit. Warning: Interface configuration for current unit will be
lost! Proceed to renumber [confirm yes/no]:”

Use the following command to renumber:

FTOS#stack-unit 1 renumber 5
Renumbering will reset the unit. Proceed to renumber [confirm yes/no]:

If the new number which we want to assign is already used by an existing member of the stack, the
below error will occur.
