The switch with the next highest MAC address is elected as Standby Master. To configure the stack so that the roles are assigned according to pre-determined priorities, enter the stack-unit priority command as described in the Note below. To reload the stack, connect the terminal to the Master Switch and enter the reload command in EXEC Privilege mode. If you connect the terminal to a member (non-Master) switch, you will not be able to access the CLI. To determine which switch is the Stack Master, enter the show system command at the terminal. To remove a port from stacking mode, use the no form of the stack-unit stackgroup command; for example, no stack-unit 0 stack-group 0. After entering the command, save the configuration and reload the switch for the change to take effect. When the reload completes, the port comes up in 40GbE mode if it is on the base module and in 4x10GbE (quad) mode if the port is on a plug-in module. NOTE: You can also manually configure the switch that will be master by entering the stack-unit unit-number priority number command in CONFIGURATION mode on each stacked switch, where: stack-unit unit-number identifies the switch in the stack. priority number specifies the management priority.

Assembling a Switch Stack

lower 40GbE base-module port and
stack-group 1
defines the stack group
for the upper 40GbE base-module port. To display the ports in each stack
group, enter the
show system stack-unit
unit-number
stack-group
command.
2
Save the stacking configuration on the 40GbE ports:
FTOS# write memory
3
Repeat Steps 1 and 2 on each
MXL 10/40GbE Switch
in the stack by
entering the
stack-unit 0 stack-group 0
and
stack-unit 0 stack-group 1
commands and saving the configuration.
4
Reboot each switch by entering the reload command in EXEC Privilege
mode:
FTOS# reload
If the stacked switches all reboot at approximately the same time, the
switch with the highest MAC address is
automatically elected
as the
Master Switch. The switch with the next highest MAC address is elected
as Standby Master.
To configure the stack so that the roles are assigned according to
pre-determined priorities, enter the
stack-unit priority
command as
described in the Note below.
To reload the stack, connect the terminal to the Master Switch and enter the
reload
command in EXEC Privilege mode. If you connect the terminal to a
member (non-Master) switch, you will not be able to access the CLI.
To determine which switch is the Stack Master, enter the
show system
command at the terminal.
To remove a port from stacking mode, use the
no
form of the
stack-unit stack-
group
command; for example,
no stack-unit 0 stack-group 0
. After entering the
command, save the configuration and reload the switch for the change to take
effect. When the reload completes, the port comes up in 40GbE mode if it is
on the base module and in
4x10GbE (quad) mode if the port is on a plug-in
module.
NOTE:
You can also manually configure the switch that will be master by entering
the
stack-unit
unit-number
priority
number
command in CONFIGURATION mode on
each stacked switch, where:
stack-unit
unit-number
identifies the switch in the stack.
priority
number
specifies the management priority. Range: 1-14. Default: 0.
The switch with the highest priority number is elected Master. The switch with the
next highest priority number is elected Standby Master and takes over stack
