New Features for Release 5.2.4
This section highlights new NCS 4000 features for Release 5.2.4. For detailed documentation of each of these features, see the user documentation
Hardware
Cisco NCS 4009 and Cisco NCS 4016 chassis have been introduced as part of Cisco NCS 4000 Series.
Route Processor Card
The route processor card provides the intelligence of the system by functioning as the shelf controller for NCS4K-2H-W or OTN applications and by providing route processing and chassis management. The route processor card also monitors system alarms and control the system fans.
Fabric Card
The fabric card provides the switch fabric for the routing system and perform the cross-connect function of the routing system, connecting every line card to each other. The switch fabric receives ingress user data from one line card slot and performs the switching necessary to route the data to the appropriate egress LC slot.
20-Port 10GE OTN Line Card
The 20-port 10GE OTN LC (NCS4K-20T-O-S) line card supports any combination of the following interfaces, up to:
2-Port 100GE OTN Line Card
The 2-port 100GE OTN LC (NCS4K-2H-O-K) supports any combination of 100GE and OTU4 interfaces using Cisco NCS4K-2H-O-K pluggable optics.
2-Port 100GE NCS4K-2H-W Line Card
The 2-port 100GE NCS4K-2H-W line card (NCS4K-2H-W) card is a tunable NCS4K-2H-W trunk card, which simplifies the integration and transport of two 100 Gigabit Ethernet or OTU-4 signals into enterprises or service provider networks. The card is ITU-T G.709 compliant and supports 96 wavelengths, spaced at 50-GHz over the entire C band. The card also features two NCS4K-2H-O-K pluggable optics that can map each client signal to a single NCS4K-2H-W line interface
Software Packages
The following software packages are present in Cisco NCS 4000, Cisco IOS XR Release 5.2.4:
New Software Features
These software features have been introduced in Release 5.2.4:
ODU and ODU Cross Conections
In the case of channelization, ODU is created as a sub controller of an OTU controller Optical Channel Data unit (ODU ) allows you to support tandem connection monitoring (TCM), path monitoring (PM) and automatic protection switching (APS) of OTN traffic.End-to-end path supervision and client adaptation is made possible by using the OPU. The ODU provides two important overheads : the PM overhead and the TCM.
OSPF
Open Shortest Path First (OSPF) is a routing protocol designed to run an autonomous system. It maintains an identical database describing the topology of an autonomous system. From the identical database, a shortest path-tree calculates the routing table. OSPF-TE allows controlling the data packet's path.
Tandem Connection Monitoring
Tandem Connection Monitoring (TCM) application is performed at ODUk layer, some bytes of the overhead are reserved for applications.
TCM application allows you to setup and monitor the Trail Trace Identifier (TTI) as well as the BIP-8 error monitoring to receive alarms or manage statistics.
Multiplex Container
Based on definitions for G.709, the following multiplex containers are supported:
Multiplex Mapping and Rate Adaptation
Based on definitions for G.709, the following multiplex mapping and rate adaptation are supported:
GCC Management
General Communication Channel (GCC) is an in-band side channel that carries transmission management and signaling information within optical transport network elements. Maximum 30 channels are supported in GCC links.
ISSU Upgrade
In-Service Software Upgrade (ISSU) is a technique used to update the software packages on a network device without affecting the traffic. By using ISSU, you can apply bug fixes and deploy new features and services of the complete Cisco IOS XR Software image.
GMPLS
Generalized Multi-Protocol Label Switching (GMPLS) allows to define and view the fiber and alien wavelength parameters that are used during GMPLS circuit creation. It ranges the packet based data on MPLS protocol to allow the creation and maintenance of channels across the networks. It contains non-packet switching devices.
Cisco Bug Search Tool
Use the Bug Search Tool (BST) to view the list of outstanding and resolved bugs in a release.
BST, the online successor to Bug Toolkit, is designed to improve the effectiveness in network risk management and device troubleshooting. The tool allows partners and customers to search for software bugs based on product, release, and keyword, and aggregates key data such as bug details, product, and version. The tool has provision to filter bugs based on credentials to provide external and internal bug views for the search input.
Search Bugs in BST
Procedure
Step 1 Go to https://tools.cisco.com/bugsearch/. You will be prompted to log into Cisco.com. After successful login, the Bug Toolkit page open. Step 2 To search for release 5.2.4 bugs, enter the following parameters in the page: Step 3 Press Enter.
By default, the search results include bugs with all severity levels and statuses, and bugs that were modified during the life cycle of the bug. After you perform a search, you can filter your search results to meet your search requirements.
An initial set of 25 search results is shown in the bottom pane. Drag the scroll bar to display the next set of 25 results. Pagination of search results is not supported.
