Step Task
5 Configure the ports on the added switch for
stacking, where:
stack-unit 0 defines the default ID unit-number
in the initial configuration of a switch.
stack-group
stacking.
6 Save the stacking configuration on the ports.
7 Reload the switch. FTOS automatically assigns a
number to the new unit and adds it as member
switch in the stack. The new unit synchronizes its
running and startup configurations with the stack.
If a standalone switch already has stack groups configured.
Step Task
8 Attach cables to connect the ports already configured as stack groups on the switch to one or more switches in the
stack.
9 FTOS automatically assigns a number to the new unit and adds it as member switch in the stack. The new unit
synchronizes its running and startup configurations with the stack.
FTOS Behavior: When you add a new switch to a stack:
• If the new unit has been configured with a stack number that is already assigned to a stack member,
the stack avoids a numbering conflict by assigning the new switch the first available stack number.
• If the stack has been provisioned for the stack number that is assigned to the new unit, the
pre-configured provisioning must match the switch type. If there is a conflict between the provisioned
switch type and the new unit, a mismatch error message is displayed.
Merge Two S-Series Stacks
You may merge two stacks while they are powered and online. To merge two stacks, connect one stack to
the other using user port cables from the front end user port.
• FTOS selects a master stack manager from the two existing managers based on the priority of the
stack.
• FTOS resets all the units in the losing stack; they all become stack members.
• If there is no unit numbering conflict, the stack members retain their previous unit numbers.
Otherwise, the stack manager assigns new unit numbers, based on the order that they come online.
• The stack manager overwrites the startup and running config on the losing stack members with its own
to synchronize the configuration on the new stack members.
