New and Changed Software Features in Cisco IOS XE 17.14.1a

Table 1. Software Features

Feature

Description

QFP Drops Threshold and Warning

From Cisco IOS XE 17.14.1a, this feature enables you to configure the warning threshold for each drop cause, and the total QFP drop in packets per second. If the configured threshold exceeds, then a rate-limited syslog warning is generated. You can configure the threshold using the platform qfp drops threshold command.

DC-PE Router in Cisco ACI to SR-MPLS Hand-off

From Cisco IOS XE 17.14.1a, Cisco ASR 1000 Series Aggregation Services Routers and Cisco Catalyst 8500 Series Edge Platforms can be used as intermediate DC-PE devices in Cisco ACI to SR-MPLS hand-off interconnection. SR-MPLS hand-off is an interconnection option that enables Cisco ACI to WAN interconnect using Segment Routing (SR) MPLS underlay.

IP Endpoint Delay Measurement and Liveness Monitoring

This feature enables you to measure the end-to-end delay and monitor liveness towards either a specified IPv4 or IPv6 endpoint. From Cisco IOS XE 17.14.1a, you can configure this feature using the performance-measurement endpoint and performance-measurement delay-profile endpoint commands.

Enhanced IS-IS Fast Flooding

The IS-IS Fast Flooding feature optimizes LSP transmission to accelerate network convergence by dynamically adjusting the LSP rate based on receiver capability. From Cisco IOS XE 17.14.1a, IS-IS Fast Flooding can be configured using the router isis lsp-fast-flooding command. The LSP transmission can be further customized with arguments such as max-lsp-tx , psnp-interval , and per-interface within the samerouter isis command, and enhanced by using the isis remote-psnp-delay command. This feature is disabled by default, and requires manual configuration to enable.

Support for Suite B Ciphers with GET VPN

From Cisco IOS XE 17.14.1a, this enhancement introduces support for Suite B ciphers with GET VPN on the following platforms and its corresponding models:
  • Cisco ASR 1000 Series Aggregation Services Routers:- ASR 1000 with ESP100-X

  • Cisco Catalyst 8300 Series Edge Platforms:- C8300-1N1S-4T2X, C8300-2N2S-6T

  • Cisco Catalyst 8200 Series Edge Platforms:- C8200L-1N-4T

  • Cisco Catalyst 8500 Series Edge Platforms:- C8500-12X4QC, C8500L-8S4X

  • Cisco 1000 Series Integrated Services Routers:

    • C1131

    • C112X

    • C116X

    • C111X

Increase in L2TPv3 Scalability

From Cisco IOS XE 17.14.1a, the capacity for unidimensional scalability of L2TPv3 tunnel is increased to 12,000 for the following platforms:

  • Cisco ASR 1000 Series Aggregation Services Routers using RP3 with ESP200-X and ESP100-X

  • Cisco Catalyst 8500 Series Edge Platforms

The scalability is increased to 8000 for Cisco Catalyst 8500L-8S4X Platform.

Support to Configure VPN Solutions for SD-Routing devices

This release introduces support for the following VPN solutions:

  • FlexVPN

  • GETVPN

  • DMVPN

  • L3VPN

These VPN solutions can be configured by using Configuration > Configuration Groups > CLI Add-on Profile option in Cisco SD-WAN Manager.

This release introduces support for the following YANG Configurational Models:
  • BGP

  • MPLS

  • RSVP

  • SNMP

  • AAA

  • QOS

  • ACL

  • DHCP

Enhancement to the show reload-history Command

From Cisco IOS XE 17.14.1a, the show reload-history command is modified toshow reload history.The output for the command is updated to include crash data, Cisco High Availability (HA) status, and software version.

View Unmodelled Commands on SD-Routing Devices

After an SD-Routing device is deployed, you can view the unmodelled commands on Cisco SD-WAN Manager. The list of unmodelled commands are regenerated if the device reboots.

Configure Secure Service Edge

Secure Service Edge is a cloud solution that provides seamless, transparent, and secure Direct Internet Access (DIA) to protect against internet-based threats. This solution can be configured through Policy Groups by using Cisco SD-WAN Manager.

Configuration Group Enhancements

This release introduces support for the following in Cisco SD-WAN Manager:
  • Transport Profiles

  • Management Profile

  • Service Profile

  • CLI Profile

  • Policy Object Profile

Voltage and Current Metrics

Power Entry Module (PEM) sensors are critical components in the device that are responsible for monitoring various aspects of the power supply, such as voltage, current, and sometimes temperature, to ensure the device operates within safe and efficient parameters. From Cisco IOS XE 17.14.1a, you can use the show environment command to display the PEM sensor readings in mV (milli-volt) and mA (milli-ampere) for your devices..
