Instructions


1. Update each switch to the latest firmware using the instruction in the .zip file.

2. Configure ports to be used for stacking. It is recommended to use at least two ports on each switch to allow a ring topology connection.

 
NOTE: A reboot of the switch is required for the ports to transition into stacking mode.
 
NOTE: You may stack on the 10 Gigabit or Forty-Gigabit ports, but not both.
 
Command Parameters
console>enable Enter Privileged EXEC mode.
console#configure  Enter configuration mode.
console(config)#stack Enter Stack Configuration mode.
console(config-stack)#stack-port [Port name] [Port Number] stack Configure Port as stack port.
console(config-stack)#end Go Back to Configuration Mode.
console#copy running-configuration startup-configuration Save Configuration
console#reload Reboot


The below example demonstrates how to convert a Forty-Gigabit ports port to a stack port.

We are using ports fortygigabitethernet 1/1/1 and fortygigabitethernet 1/1/2 as an example.

console>enable
console#config
console(config)#stack
console(config-stack)#stack-port fortygigabitethernet 1/1/1 stack
console(config-stack)#stack-port fortygigabitethernet 1/1/2 stack
console(config-stack)#end
console#copy running-configuration startup-configuration
console#reload

Below example demonstrates how to convert a 10 Gigabit ports to a stack port.

We are using ports tengigabitethernet 1/0/23 and stack-port tengigabitethernet 1/0/24 as an example.

console>enable
console#config
console(config)#stack
console(config-stack)#stack-port tengigabitethernet 1/0/23 stack
console(config-stack)#stack-port tengigabitethernet 1/0/24 stack
console(config-stack)#end
console#copy running-configuration startup-configuration
console#reload
 

3. After a successful reboot, verify the stack ports are configured properly.

Use command "show switch stack-ports"


Sample output
 

console#show switch stack-ports

              Configured Running

               Stack        Stack      Link        Link           Admin

Interface   Mode      Mode      Status       Speed (Gb/s)  Status

---------------- ---------- ---------- ------------ ------------ -----------

Te1/0/23     Stack     Stack       Link Up    10       Enabled

Te1/0/24     Stack     Stack       Link Up    10       Enabled

 

4. Power off the switches. Connect the stacking ports in a ring topology.

5. Power on the wanted primary switch first and wait until you can manage it. Afterward power on the next switch one at a time until every switch is powered on. They add themselves to the stack.
 

NOTE: The Primary and Operation Standby switches keep the startup configuration of the stack. You can only access the console port from the Primary.
 
NOTE: The N4000 series switches support up to 12 units in a stack.
  
 

To unstack a member from N4000 stack, do the following


1. Power off the member and remove stacking cables from the member which has to be removed from the stack

2. In the primary switch, remove the member id of the member which is powered off
 

Command Parameters
console>enable Enter Privileged EXEC mode.
console#configure  Enter configuration mode.
console(config)#stack Enter Stack Configuration mode.
console(config-stack)#no member <member id> Remove member


 

NOTE:  This command removes the configuration that is associated with that member from the running configuration.  The command will not work if the switch is an active member. This is not a command to renumber the unit.  It will only remove the switch as a member of the stack.
 

Sample output
 

Consider we are removing member 2 from stack.

console(config)#stack
console(config-stack)#
console(config-stack)#no member 2
 

3. If you want to use, convert the stacking ports to Ethernet use the below commands.

NOTE:  You must reboot the switch for ports to transition into Ethernet mode.

 
Command Parameters
console>enable Enter Privileged EXEC mode.
console#configure  Enter configuration mode.
console(config)#stack Enter Stack Configuration mode.
console(config-stack)#stack-port [Port name] [Port Number] ethernet Configure Port as ethernet port.
console(config-stack)#end Go Back to Configuration Mode.
console#copy running-configuration startup-configuration Save Configuration
console#reload Reboot


Below example demonstrates how to convert a 10 Gigabit port to an ethernet port.

console>enable
console#config
console(config)#stack
console(config-stack)#stack-port tengigabitethernet 1/0/1 ethernet
console(config-stack)#stack-port tengigabitethernet 1/0/1 ethernet
console(config-stack)#end
console#copy running-configuration startup-configuration
console#reload


4. After a successful reboot verify that the ports have changed to Ethernet mode.

Use command "show switch stack-ports"


Sample output
 

console#show switch stack-ports

               Configured Running

                Stack        Stack      Link        Link           Admin

Interface   Mode      Mode      Status       Speed (Gb/s)  Status

Te1/0/2     Ethernet Ethernet   Link Up    10       Enabled
