Stacks

The NS9600 and NS9500 Sensors offer the solution of stacking multiple Sensors to achieve scalability. The individual Sensors in the stack are interconnected using external stacking cables. A stack of Sensors create a unified data plane view across the stack. This allows the Manager to manage the stack as a unified device. In a stack, some of the Sensor properties like signature set and call back detector update etc. are managed at the stack level and remaining like port configuration, troubleshooting etc. are managed at the device level.

To manage a stack, go to Devices → <Admin Domain Name> → Global → Device Manager → Stacks tab. The Stacks tab displays the following details:

Option	Definition
Stack Name	Displays the name of the device. Double-clicking the name opens the Stack Details window where you can view the details of the stack.
Capacity	Displays the throughput of the stack.
Member Sensors	Displays the number of devices that are currently part of the stack. Click the number to view the names of devices that are part of the stack.
License	Displays on of the following: Required: The reason can be one of the following: License has not been assigned to the stack. The license is assigned, but its capacity is less than the stack's configured capacity. Present: The license is present for the stack. Expired: The license is assigned, but has expired. Grace Period: The license has expired and running on grace period. Note A grace period of 30 days is provided to subscription-based System licenses after they expire. Note You can view or assign license(s) to the stack by clicking the icon. For more details, see Add a stack to the Manager.
Deployment Mode	Displays one of the following based on the mode configured during creation of stack: Direct Indirect
HA Pair	If the stack is part of a HA pair, the name of the HA pair is displayed.
Comment	Displays the comment added for the stack.
