What's New in Cisco NCS 4000 Series, Release 6.5.35
Cisco is continuously enhancing the product with every release and this section covers a brief description of key features and enhancements.
| Feature | Description |
|---|---|
|
Hardware Installation |
|
|
The NCS4K-4H-QDD-P line card is a new addition to the NCS 4000 platform. It uses the Bright DCO pluggable variant, DP04QSDD-HE0, to scale WDM traffic from 100G to 400G in 100G increments, providing flexibility and high performance across regional, metro, and long-haul routes.This line card has eight port interfaces:
|
|
|
The NCS4K-4H-OPW-QC2 line card is compatible with the QSFP-100G-ZR4-S pluggable for ports 0,1,5, and 6, supporting a data rate of 100 Gbps. The QSFP-100G-ZR4-S pluggable supports configurations for Ethernet or Ethernet over OTN controllers only. |
|
| Feature | Description |
|---|---|
|
Configuration |
|
|
The 100MHz flex-grid-spacing feature is now supported on the NCS4K-4H-QDD-P card. Configuration can be done on Bright ZRP optics ports 4 to 7 using the Cisco Transport Controller (CTC) interface or command-line interface (CLI). |
|
|
BFD fast detect strict-mode when enabled allows to block the establishment of a BGP session until a BFD session is successfully established. In default behaviour, BGP session establishment operates independently of the BFD state change, meaning a BGP session can be established even if the BFD state is down or dampened. The newly introduced optional keyword, strict-mode, prevents a BGP session from being established if the BFD is in a down state. When BFD is dampened or down, the routing protocol states or sessions cannot be initiated. Keyword Added:
|
|
|
You can now perform an Ethernet Service Activation Test (SAT) on the NCS4K-4H-QDD-P Line Card. Ethernet SAT helps test service turn-up, installation, and troubleshooting of Ethernet-based services. |
|
|
Field Programmable Device (FPD) Upgrade for NCS4K-4H-QDD-P Line Card |
You can now perform FPD upgrades on the NCS4K-4H-QDD-P line card. Upgrading the line card is essential to ensure its proper functioning. |
|
GMPLS UNI circuits can now be created for the NCS4K-4H-QDD-P line card. This enhancement optimizes network resources and improves network utilization across packet and optical networks. |
|
|
You can now configure the NCS4K-4H-QDD-P line card in port mode and breakout mode with 25GE, 100GE, and 400GE data rates. This enhancement offers flexibility and high performance across regional, metro, and long-haul routes. |
|
|
Link Layer Discovery Protocol (LLDP) for NCS4K-4H-QDD-P Line Card |
You can now configure LLDP on the packet interfaces of the NCS4K-4H-QDD-P line card. |
|
This feature enables the redirection of test traffic from the destination network to the source network in Loopback Message (LBM) format. The Loopback Message allows the measurement of various parameters and performance metrics, such as frame delay, frame loss rates, and QoS settings, after the traffic has completed its round trip. Such comprehensive measurement helps identify issues within the network setup. You can also use it to ensure the service is running and meets the SLA. |
|
|
The Pseudo Wire ping enables you to test connectivity between Provider Edge (PE) devices and identify any connection breakages. |
|
|
This feature introduces a secret command that enables you to choose encryption types, such as Type 5, Type 8, Type 9, and Type 10, for encrypting the Secret. This feature employs hashing algorithms to build a more secure, strong, and robust secret to enhance the device security. Commands added: |
|
|
This feature introduces strong password security policies to strengthen the secret and password configuration of usernames. These policies also have the option of blocking a local user from accessing the router for a configurable amount of time if the maximum number of attempts to log in to the device is reached. The feature thus enhances router security by enforcing strong user password policies. Commands added: |
|
|
NCS 4000 devices now support Route Reflector functionality for VPNv6 prefixes, reflecting routes without participating in data forwarding. Acting as a P-node, it uses IPv4 MPLS label switching to carry VPNv6 traffic, enabling scalable, hardware-compatible deployments with reduced control-plane state for large service provider cores. A new CLI keyword is added within the address-family configuration for BGP:
|
|
|
NCS 4000 Bundle Convergence Time Improvement |
In this release, the bundle convergence time is improved in the event of:
This enhancement reduces the traffic outage duration during bundle operational impact. |
|
Changes in show ethernet service-activation-test profile Command |
The output of the show ethernet service-activation-test profile command now includes the duration field. |
|
Prior to R6.5.31, Flow-Aware Transport Pseudowire (FAT-PW) load balancing is supported on the Link Aggregation Group (LAG) NNI interface with the insertion of up to three labels. From R6.5.31 onwards, FAT-PW load balancing is supported on the LAG NNI interface with the insertion of up to five labels. This enhancement allows the flow-aware traffic to be optimally load-balanced among all the links on the LAG AC interfaces. |
|
|
ACL allows you to control the packets that move through the network. This control allows you to limit the network traffic and restrict the access of users and devices to the network. NCS 4000 supports the following ACL:
|
|
|
The IPv4 VRF support for Layer 3 is now suported by the NCS4K-4H-QDD-P line card. ACL and QoS are not supported simultaneously on the same interface. |
|
|
Bidirectional Forwarding Detection (BFD) over Link Aggregation Group (LAG) |
BFD allows you to detect network failures between neighbors. Two modes are supported:
Commands added:
|
The following features are also introduced in this release:
-
You can now use In-Service Software Upgrade through OLR mechanism to deploy new Cisco IOS XR Software images that supports new software features and services.
-
On a Ethernet Service Activation Test (SAT) interface with internal direction, QoS policies apply to both transmitted and received packets.
-
Ethernet Service Activation Test (SAT) can now be performed on both tagged and untagged interfaces.
-
You can now define the MTU packet size in SAT, allowing for tailored testing that matches the network's maximum frame capacity.
-
SAT now supports testing of various packet sizes and provides throughput analysis, considering both frame sizes and interface bandwidth.
-
You can now configure a color-aware profile for SAT.
-
The SAT feature supports up to four parallel SAT sessions in a single chassis and up to four parallel SAT sessions for each rack in a multi-chassis.
-
You can remotely test the throughput of an Ethernet port and verify the maximum rate of frame transmission without frame loss.
-
SAT can now detect out-of-sequence packets.
-
SAT External direction now supports all frame sizes, with a maximum throughput of 21G.
-
Ethernet Data Plane Loopback now supports different Layer 2 VLAN translations and encapsulations.
-
From this release, Cisco NCS 4000 complies with the Cisco Security Policy defined by the TPSB.
-
The port-mode yang model now supports the opu4 framing for the otn controller.
