The slices screen provides a way for you, as a network administrator, to partition networks into many logical networks. This feature allows you to create multiple disjoint networks and assign different roles and access levels to each one. Each logical network can be assigned to departments, groups of individuals, or applications. Multiple disjoint networks can be managed using the Cisco Nexus Data Broker application.
The slices are created based on the following criteria:
Network devices—The devices that can be used in the slice.
Network devices can be shared between slices.
Network device interfaces—The device interfaces that can be used in the slice.
Network device interfaces can be shared between slices.
Flow Specification—A combination of source and destination IP, protocol, and source and destination transport ports used to identify the traffic that belongs to the slice.
Flow specifications can be assigned to different slices if the associated network devices and interfaces are disjointed.
You can also use VLAN IDs to segregate the slice traffic.
Slices must be created by a Cisco Nexus Data Broker user with the Network Administrator role. After creation, the slices can be managed by a user with the Slice Administrator role.
Slices can overlap if each slice has at least one unique attribute. For example, a slice can share the same physical switches and ports, but be differentiated by the type of traffic it receives.
