Cisco IOS XR Release 6.3.2 contains all features released in Cisco IOS XR Release 6.3.1. Release 6.3.1 is a limited availability (LA) release. For more information on IOS XR Release 6.3.1 features, see Release Notes for Cisco NCS 6000 Series Routers, IOS XR Release 6.3.1
The Cisco Network Convergence System (NCS) 6000 series router
delivers outstanding network agility, packet optical convergence, and a system
scale measured in petabits per second. It also facilitates the build-out of
next-generation core to:
capacity at the lowest total ownership cost
high-bandwidth mobile, video, and cloud services
Running the Cisco IOS XR operating system, Cisco's innovative
virtualized operating environment, the Cisco NCS 6000 series router advances
the concept of distributed routing and virtualization. With Cisco Virtualized
IOS XR, the Cisco NCS 6000 series router brings new levels of programmability
and virtualization to:
application service offerings
The Cisco NCS 6000 series router is engineered for environmental
efficiency, with the use of adaptable power consumption. The Cisco NCS 6000
series router is powered by the Cisco nPower Network Processor Units (NPU).
These technologies aid the Cisco NCS 6000 series router to achieve the lowest
carbon footprint in service provider routing.
The Cisco NCS 6008 router, part of the Cisco NCS 6000 series routers, is the next-generation core routing system that provides industry-leading 16 Tbps of full-duplex network bandwidth through single chassis, and 32 Tbps of full-duplex network bandwidth through multi-chassis with eight line cards per chassis.
The Cisco NCS 6008 router runs on Cisco IOS XR software with
Linux as the underlying host operating system. A Kernel-based Virtual Machine
(KVM) hypervisor provides a virtualized environment to independently run system
administration and routing functions on separate virtual machines. This
provision makes the new system versatile and robust, and provides immense
flexibility for future expansion without the need for a complete system
A multi-slice architecture of line cards enables the system to
be configured in a mixed operating mode, simultaneously supporting traffic at
10 Gbps and 100 Gbps on slice-level granularity.
This release notes describe the features provided in the Cisco IOS XR Software Release
for the Cisco NCS 6000 series router and are updated as needed.
