• 1 PPS Pulse Width Configuration

  On the Cisco NCS 4202 chassis, the 1 PPS pulse bandwidth can be changed from the default value of 500 milliseconds to up to 20 microseconds. For more information, see Configuring Clocking and Timing.

• Alarm support for 900W

  Effective Cisco IOS XE Everest 16.6.1, on Cisco RSP3 module, alarm notification is enabled on 900 watts DC power supply. For more information, see Cisco NCS 4200 Series Software Configuration Guide, Cisco IOS XE Everest 16.6.1.

• IP SLA Statistics UDP Jitter

  Effective Cisco IOS XE Everest 16.6.1, time stamping for sender (T1, T4) and receiver (T3, T2) is performed by hardware, instead of software to improve the accuracy of jitter and latency measurements. For more information, see IP SLAs Configuration Guide Cisco IOS XE Everest 16.6.1. For more information, see IP SLAs Configuration Guide, Cisco IOS XE Everest 16.6.1 (Cisco NCS 4200 Series).

• PVST+/RPVST+

  Cisco ASR routers can use the per-VLAN spanning-tree plus (PVST+) protocol based on the IEEE 802.1D standard and Cisco proprietary extensions, or the rapid per-VLAN spanning-tree plus (rapid-PVST+) protocol based on the IEEE 802.1w standard. For more information, see LAN Switching Configuration Guide, Cisco IOS XE Everest 16.6.1 (Cisco NCS 4200 Series).

• Segment Routing – Traffic Engineering

  Segment Routing – Traffic Engineering (SR-TE) provides a simple, automated, and scalable architecture to engineer traffic flows in a network. For more information see, Segment Routing for Cisco IOS XE Everest 16.6.1.
