Brocade FastIron Ethernet Switch Stacking Configuration Guide - Manual (Page 157)

Mixed stack example
In this example, ICX 6450 peripheral devices are removed from a mixed stack. The mixed stack
contains two ICX 6610 devices in a ring configuration in the backbone. There are two substacks of three
ICX 6450 devices each in the mixed stack.
The following show stack output shows the configuration of the mixed stack before the stack
unconfigure mixed-stack command is executed. The show stack command is executed on the active
controller.
Brocade(config)# show stack

The following sequence shows the stack unconfigure mixed-stack command being executed on the
active controller. After confirmation, all peripheral ports and peripheral trunks are removed from the ICX
6610 devices. The peripheral ICX 6450 devices recover their configurations from before they were
members of the mixed stack, and they are reloaded.
Brocade# stack unconfigure mixed-stack
All the peri-ports/trunks will be removed and all the ICX6450 units will recover
pre-mixed-stacking configuration. Are you sure? (enter 'y' or 'n'): y
Removed peri-ports from configuration: 1/3/1 1/3/7
Removed peri-trunks from configuration: 2/3/1-to-2/3/2 2/3/7-to-2/3/8
The show stack command is executed on the active controller. The output shows that the ICX 6450
devices are no longer part of the mixed stack, because the MAC addresses are all zeroes, the State
column shows “reserve,” and the device status in the Comment column does not show “Ready.”
The Role column still shows “member” because the active controller retains the configuration of the
former stack member in reserve so that it can form a stack later if stack merge or stack formation
happens.
