This section highlights new NCS 4000 features for Release 6.5.25:
Software
The following software features have been introduced in Release 6.5.25:
1+1+R
In 1+1+R protection mechanism, a circuit is protected by two redundant paths, one is the protect path and the other one is the restore path. When a failure occurs on the working and the protect paths, then the restore path takes over. Wait to Restore (WTR) timers are available on both the working and protect paths. Restoration path signaling is triggered as soon as a defect is detected on either of the paths (working or protect). When the working path fails, the traffic shifts to the protect path. In this period of time, the restore path is also ready to take over, if the protect path fails.
Affinity Support for OTN GMPLS
The Affinity Support for OTN GMPLS feature steers the selection of paths for MPLS TE tunnel, adhering to affinity constraints.The feature enables you to handle ISSU (OLR) upgrades on NCS4K more gracefully.
AINS Support for Controllers
The automatic-In-Service (AINS) state with a soak time period can be configured on a controller so that after the completion of a maintenance window, the controller can be removed from the maintenance state without manual intervention. After the expiry of the soak time period, the state automatically goes to the normal or the In-Service state.
BGP Labeled Unicast and Prefix Independent Convergence
BGP labeled unicast (LU) enables MPLS transport across IGP boundaries. By advertising loopbacks and label bindings across IGP boundaries, we can communicate with other routers in remote areas that are not part of the local IGP. BGP LU advertisements impact edge routers and border routers. The Border Gateway Protocol Prefix Independent Convergence Unipath (BGP PIC Unipath) primary/backup feature provides the capability to install a backup path into the forwarding table. Installing the backup path provides prefix independent convergence in the event of a primary PE–CE link failure. The primary/backup path provides a mechanism for BGP to determine the best backup path.
Cable Management Utility
The cable management wizard can be used to make CXP connections between the fabric cards of the FCCs and LCCs in a multi-shelf configuration. The CXP connections are color coded.
FAT Pseudo wire
FAT pseudo wires are used to load balance traffic in the core. A flow label is a unique identifier to distinguish a flow within the pseudowire and is derived from the payload of a packet. On the imposition PE node, the flow label is inserted. At the disposition PE node, hashing is performed using the terminated headers, including the flow label to balance traffic across bundle members.
Inter-rack RP pairing
In a multi chassis (MC) system, there is a possibility that the rack which houses the active RP and standby RP may go down. This results in the reboot of all the line card chassis, thus impacting traffic of the MC system. Inter-rack (or cross-rack) pairing allows pairing route processors (RP) between racks to provide high availability (HA) against rack failures. The RP of one rack is paired with an RP in the next rack. In case of failure of the rack which houses the active RP, the standby RP which is in another rack takes over.
Inter-rack Timing
In a multi chassis (MC) system, the source and destination ports of the cross connect can be across racks. Inter-rack (or cross-rack) timing allows the timing information to be passed across racks for segmentation and re-assembly needs.
L3 Link Aggregation
Link Aggregation (LAG) is a mechanism used to aggregate physical interfaces or ports to create a logical entity called link bundle. LAG is a trunking technology that groups together multiple full-duplex Ethernet interfaces to provide fault-tolerant high-speed links between switches, routers, and servers. LAG is supported for both L2 and L3 interfaces.
Low rate on 24LR card
To handle low rate client signal on NCS4K, this feature provides low rate (OC3/OC12/STM1/STM4 ) data path support on NCS4K-24LR-O-S line card.
Migration from NCS4K-ECU to NCS4K-ECU2
ECU2 is the external connection unit intoduced to support NCS4K Multi Chassis environment. The procedure provides steps to migrate from NCS4K-ECU to NCS4K-ECU2.
For more information on the above software features, see the Configuration Guide for Cisco NCS 4000 Series.
Single Chassis to Multi Chassis Migration
Multiple Cisco NCS 4016 single chassis (SC) are connected to one or more NCS 4000 fabric card chassis (FCC) to form a multi chassis (MC) system. This enables scalability with single admin and control plane. The MC system contains two types of chassis - line card chassis (LCC) which is the NCS 4016, and the FCC. The supported MC configurations are:
-
1 LCC and 1 FCC (1+1)
-
2 LCCs and 1 FCC (2+1)
-
3 LCCs and 1 FCC (3+1)
-
4 LCCs and 1 FCC (4+1)
-
1 LCC and 2 FCCs (1+2)
-
2 LCCs and 2 FCCs (2+2)
-
3 LCCs and 2 FCCs (3+2)
-
4 LCCs and 2 FCCs (4+2)
-
1 LCC and 3 FCCs (1+3)
-
2 LCCs and 3 FCCs (2+3)
-
3 LCCs and 3 FCCs (3+3)
-
4 LCCs and 3 FCCs (4+3)
-
4 LCCs and 4 FCCs (4+4)
For more information on the above software features, see the Migration of Single Chassis to Multi Chassis for Cisco NCS 4000 Series.
Support TCA as an Alarm
Threshold Cross Alert (TCA)started when the Performance Monitoring (PM) counters cross the predefined threshold values. For details about this alarm, see the Alarms Troubleshooting Guide for Cisco NCS 4000 Series .

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.
