If they are using Kilo then Control Center 11.0 Beta has to be used.



How to patch driver

V1 Setup: Patch NetScaler v1 driver to neutron-lbaas as follows.
Copy the driver netscaler_driver.py from netscaler_driver_v1.zip to neutron_lbaas/services/loadbalancer/drivers/netscaler/netscaler_driver.py

Changes in configuration files:

(/etc/neutron/)neutron.conf #Ensure LBaaS v1 plugin is enabled in service plugin.

??

service_plugins = neutron.services.l3_router.l3_router_plugin.L3RouterPlugin,neutron_lbaas.services.loadbalancer.plugin.LoadBalancerPlugin

??

#NCC related changes

??

[netscaler_driver] netscaler_ncc_uri = http://<ncc ip>:80

netscaler_ncc_username = openstack_driver

netscaler_ncc_password = freebsd

periodic_task_interval = 5

netscaler_status_collection=False,300

is_synchronous=False

netscaler_ncc_cleanup_mode = False

??

(etc/neutron/)neutron_lbaas.conf

#Ensure netscaler v1 driver is enabled in servcie provider.

??

service_provider=LOADBALANCER:NetScaler:neutron_lbaas.services.loadbalancer.drivers.netscaler.netscaler_driver.NetScalerPluginDriver

??

Restart neutron service.

OpenStack was not updated correctly
There was also an issue where??driver files are not patched properly from the driver bundle. Please make sure files ( ncc_client.py and netscaler_driver.py ) are patched.??
