The object is to add an additional Management CPU to the NetScaler MPX for Management data processing and monitoring.
You can use the NetScaler CLI, GUI, or NITRO API to allocate an extra management CPU. This section includes the following topics:
Allocate or deallocate an extra management CPU by using the NetScaler CLINote: After you enable and disable this feature, the NetScaler appliance displays a warning to restart the appliance, for the changes to take effect.
To show the configured and effective state of an extra management CPU
Note: In this example, the show command is entered before restarting the appliance.

To allocate an extra management CPU by using the NetScaler GUI:
Use the following NITRO methods and formats to enable, disable, and show an extra management CPU.
To enable an extra management CPU
HTTP Method: POST
URL: http://<NSIP>/nitro/v1/config/systemextramgmtcpu?action=enable
Payload: {"systemextramgmtcpu":{}}
curl -v -X POST -H "Content-Type: application/json" -u nsroot:nsroot http://10.102.201.92/nitro/v1/config/systemextramgmtcpu?action=enable -d '{"systemextramgmtcpu":{}}'
To disable an extra management CPU
HTTP Method: POST
URL: http://<NSIP>/nitro/v1/config/systemextramgmtcpu?action=disable
Payload: {"systemextramgmtcpu":{}}
curl -v -X POST -H "Content-Type: application/json" -u nsroot:nsroot http://10.102.201.92/nitro/v1/config/systemextramgmtcpu?action=disable -d '{"systemextramgmtcpu":{}}'
To show an extra management CPU
HTTP Method: GET
URL: http://<NSIP>/nitro/v1/config/systemextramgmtcpu
curl -v -X GET -H "Content-Type: application/json" -u nsroot:nsroot http://10.102.201.92/nitro/v1/config/systemextramgmtcpu
