To display the stack MAC addresses, enter the show stack command.
device(config)# show stack
alone: standalone, D: dynamic config, S: static config
ID Type Role MAC Address Prio State Comment
1 S FCX648p active 0000.00d5.9380
80 local Ready
2 S FCX648 member 0000.0066.8880
0 remote Ready
3 S FCX624 standby 0000.00dc.0ec0
40 remote Ready
Current persistent MAC is 0000.00d5.9380
device(config)# stack mac 000.011.111
Error: persistent stacking MAC address timer is configured
device(config)#
The following example shows what the Persistent MAC information looks like in the output of the show
stack command when the standby controller becomes the active controller.
device# show stack
alone: standalone, D: dynamic config, S: static config
ID Type Role MAC Address Prio State Comment
1 S FCX648P active
0000.0000.0000 80 reserved
2 S FCX648 standby
0000.0066.8880 0 remote Ready
3 S FCX624 master 0000.00dc.
0ec0 40 local Ready
device#Persistent MAC timer expires in 59 minutes 52 seconds.
Current persistent MAC is 0000.00d5.9380
Unconfiguring a traditional stack
The stack unconfigure command is a runtime command that returns stack units to their pre-stacking
state. When a stack unit is unconfigured, its stacking flash is removed, and its startup-config.txt flash file
is recovered. These actions apply to all units to which this command is applied, regardless of the role of
the unit in the stack.
When the stack unconfigure command is applied to the active controller, it removes stack enable
from the runtime configuration but not from the startup configuration. If you want to remove the
command from the active controller permanently, you must enter the write memory command.
When the stack unconfigure command is applied to the standby controller or a stack member (besides
the active controller) it removes stack enable from the recovered startup-config.txt and resets the unit.
NOTE
When a stack member becomes a standalone unit after the stack unconfigure command, it could
become a clean unit if it had no startup configuration flash. When a clean unit matches the active
controller’s static configuration, the active controller integrates the clean unit into the stack. Thus, the
standalone unit is reloaded to be a member of the stack. Users can avoid this problem by disconnecting
the member unit from the stack, and issuing the stack unconfigure me command at the unit to change
it to a standalone unit.
To remove the configuration from a specific traditional stack unit, or from the entire stack, enter a
command similar to the following.
device# stack unconfigure me
Syntax: stack unconfigure [ stack-unit | all | me | clean | mixed-stack ]
• stack-unit - Unconfigure the stack member with this ID
• all - Unconfigure every unit including this unit
