Configure MQTT by using protocol extensions
The following steps add a MQTT protocol to the NetScaler appliance.
Import the extension file to the NetScaler appliance, from either a web server (using HTTP) or your local workstation. For details about importing the extension file, see Import extensions.
import ns extension local:mqtt_generic_fs.lua mqtt_code
Add a new user TCP based protocol to the system by using the extension.
add user protocol MQTT -transport TCP -extension mqtt_code
Add a service of type USER\_TCP to indicate that this is a user-defined protocol.
add service s1 10.102.90.112 USER_TCP 80
Add a user load balancing vserver and bind backend services to it.
add lb vs mysv USER_TCP
bind lb vs mysv s1
Add a user virtual server for the newly added protocol and make the load balancing virtual server configured in the previous step the default load balancer.
add user vs v_mqtt MQTT 10.217.24.28 80 -defaultlb mysv
Optionally, enable MQTT session persistence based on ClientID, set the persistence type to USERSESSION.
set lb vserver mysv -persistenceType USERSESSION
