Cisco Cisco Extensible Network Controller (XNC) Version 1.5

Dot1q support (QinQ) for Monitor Manager application edge port VLAN frame tagging.

Felix console integration to manage osgi bundles.

Manual consistency check and fix.

VLAN support within flow specs. 

Support for TIF rule installation on pure onePK nodes.

Support for deny rules, bidirectional filters, and other rule and filter enhancements in Monitor 
Manager application.

Release 1.5 adds support for the following application:

Virtual Patch Panel Application (P2P Forwarding application)—provides port-to-port traffic 
management within a switch or across the network without any need for physical connection 
changes or rewiring. 

Release 1.0 supports the following software features:

Extensible, modular architecture—modules can be added, updated, or deleted without restarting the 
Cisco XNC application. The architecture allows Cisco XNC functions to be extended using Java. 
The Service Abstraction Layer (SAL) enables extensible southbound interface support beyond 
OpenFlow. 

Multiple access methods and controls—management access is available through the built-in GUI or 
through Java APIs or REST APIs. Security features include role-based access control (RBAC), 
integration with enterprise authentication, authorization, and accounting (AAA), and secure control 
protocols.

Network visibility and troubleshooting—there are functions to support network topology discovery, 
network device management and forwarding rules programming, and access to detailed network 
statistics. Troubleshooting tools provide flow-level visibility for each device.

High availability through clustering—multiple instances can be deployed in an active-active model. 
The active-active deployment model makes the controller both highly available and scalable. 
Synchronization of information and state across all controllers is provided in real time, which helps 
prevent loss of information in the event of a failure.

Multiprotocol support—multiprotocol interface support allows OpenFlow 1.0 to communicate with 
devices. This support enables business applications to extend their use cases transparently across a 
multivendor network.

Release 1.0 provides the following applications:

Monitor Manager application—applies the SDN approach to provide visibility into the network 
traffic. 

Network Slicing application—provides the capability to partition the network based on physical or 
logical (flow) criteria.

Topology Independent Forwarding (TIF) application—provides the capability to define the 
forwarding path in the network based on application requirements.
