To begin using the RISE features, first install the Cisco Nexus 7000 series switch and the NetScaler ADC. Then, connect the NetScaler ADC to the Cisco Nexus 7000 switch either directly or indirectly. If you plan to connect the NetScaler ADC directly to the Cisco Nexus 7000 switch, the initial setup is done automatically by the auto-discovery feature. The following figure explains the flow of steps in the configuration of RISE.
You need to first install the Cisco Nexus 7000 series switch, and then install the NetScaler ADC.
Installing Cisco Nexus 7000 Series Switch
To install the Cisco Nexus 7000 Series Switch, see Installing Cisco Nexus 7000 Series Switch.
Installing NetScaler ADC
To install the NetScaler ADC, see Installing NetScaler ADC.
To install a virtual NetScaler ADC appliance, see Installing NetScaler Virtual Appliances on XenServer or Installing NetScaler Virtual Appliances on VMware ESX.
After you have completed the installation process, you can access the Cisco Nexus Series 7000 switch through the command-line interface (CLI) and the Citrix NetScaler appliance through the graphical user interface (GUI) or the CLI. To perform administrative tasks and also, to configure RISE, you need to access the Cisco switch and the NetScaler ADC.
Accessing the Cisco Nexus Series 7000 Switch
After installing the Cisco Nexus 7000 series switch, you can access it using the command line interface. To access the Cisco Nexus 7000 Series Switch, see Accessing the Cisco Nexus 7000 series switch.
Accessing the NetScaler ADC
After you install the Cisco Nexus 7000 series switch and the NetScaler ADC, configure the appliance to work in direct mode, indirect mode, VPC direct mode, or VPC indirect mode.
The NetScaler ADC which is directly connected to the switch is automatically configured for RISE mode and all of its ports are in operation mode. No configuration is required on the appliance in a direct mode deployment. For details on configuring RISE in direct mode, see Configuring RISE in Direct Mode.
If the direct mode is disabled. all Layer 2 (L2) discovery messages are dropped and L2 RISE discovery does not take place. While, if the direct mode is enabled, the L2 discovery messages are parsed. If L2 RISE discovery messages are successfully parsed, the Indirect Mode is automatically enabled.
If indirect mode is disabled, NetScaler RISE daemon does not listen on TCP ports 8000 and 8001. As a result, RISE heartbeats stop and RISE profiles go down. While, if indirect mode is enabled, NetScaler RISE daemon starts listening on TCP ports 8000 and 8001. As a result, RISE heartbeats may be exchanged and RISE profiles may come up.
The default setting for RISE is direct attach mode as enabled and indirect mode as disabled. With these settings, the direct attach mode works. However, indirect mode will not work. If you want to deploy NetScaler in an indirect mode setting with N7K then use the following setting:
set rise param -indirectMode ENABLED
However, if the direct mode is enabled, and NetScaler starts receiving L2 RISE discovery messages, it automatically turns the indirect mode as enabled. Otherwise, RISE direct mode does not work.
With active RISE profiles in Indirect Attach mode, the set rise param -indirectMode DISABLED command displays a warning message; Warning: Disabling indirect mode will cause any active RISE profile(s) to go down leading to RISE profiles on Indirect Attach going down.
vPC Direct Mode
The NetScaler ADC which is directly connected to the switch is automatically configured for RISE mode and all of its ports are in operation mode. No configuration is required on the appliance in a direct mode deployment. For details on configuring RISE in direct mode, see Configuring RISE in vPC Direct Mode.
vPC Indirect Mode
For information on configuring RISE, see Configuring RISE.
In a High Availability setup, the RISE deployment uses a maximum of two NetScaler ADCs. If one ADC becomes unavailable, the traffic flow is seamlessly switched to the other ADC.
For information about high availability configuration, see High Availability.
