New and Changed Software Features in Cisco IOS XE 17.15.1a

Table 1. Software Features

Feature

Description

Enhanced NAT Management

From Cisco IOS XE 17.15.1a, the Enhanced NAT Management feature enables network operators to safeguard system performance by limiting NAT translations based on CPU usage with the ip nat translation max-entries cpu command. This feature also enables streamlining NAT synchronization in redundant systems using the ip nat settings redundancy optimized-data-sync command.

Enhancements to Segment Routing over IPv6 Dataplane

From Cisco IOS XE 17.15.1a, Segment Routing over IPv6 dataplane supports these functionalities:

Enhancement to SGACL Logging

This feature enhances the Security Group-based Access Control List (SGACL) logging capability by using High Speed Logging (HSL) for Cisco IOS XE devices. SGACL logging through HSL provides an efficient and reliable logging method for security events in network environments with high-traffic volumes.

Absolute Path for HTTP or HTTPS File Transfer

The File Transfer using HTTP or HTTPs feature allows you to copy files from a remote server to your local device, using the copy command. From Cisco IOS XE 17.15.1a, you must provide the absolute file path when you execute the copy command, to transfer the file.

Network-Wide Path Insights on Software Defined (SD) - Routing Devices

Network-Wide Path Insights (NWPI) is a tool that allows network administrators to monitor Cisco SD-Routing deployment, identify network and application issues, and optimize the network.

Cisco Umbrella Scope Credentials

From Cisco IOS XE 17.15.1a, this feature provides the ability to define and configure a new single Cisco Umbrella credential for both Umbrella SIG and Umbrella DNS.

Configure Multiple WAN Interfaces on Cisco SD-Routing Devices Using a Custom VRF

You can now create a custom VRF that hosts one or more WAN interfaces. You can extend this functionality to create multiple custom VRFs with each VRF hosting multiple WAN interfaces. These WAN interfaces now function as transport interfaces to establish control connections to the Cisco Catalyst SD-WAN Manager. Having multiple WAN interfaces ensures that there is resiliency in control connections and routing of transport traffic.

Monitoring SD - Routing Alarms

From Cisco IOS XE 17.15.1a, network administrators can monitor SD-Routing device alarms on Cisco Catalyst SD-WAN Manager. This feature enables SD-Routing devices to record and store various alarms generated by control components and routers. For more information, see Cisco SD-Routing Command Reference Guide.

Configure DMVPN for SD-Routing Devices

Cisco DMVPN (Dynamic Multipoint VPN) is a routing technique to build a VPN network with multiple sites without having to statically configure all devices. This technique uses tunnelling protocols and encrypted security measures to create virtual connections, or tunnels, between sites. These tunnels are dynamically created as needed, making them both efficient and cost-effective.

Enabling Flow Level Flexible NetFlow Support for SD-Routing Devices

The Flow-level Flexible NetFlow (FNF) feature allows you to monitor the NetFlow traffic and view all the flow-level FNF data that is captured including application-level statistics.

Network-Wide Path Insights on SD-Routing Devices

Network-Wide Path Insights (NWPI) is a tool that allows network administrators to monitor Cisco SD-Routing deployment, identify network and application issues, and optimize the network.

Seamless Software Upgrade for SD-Routing Devices

This feature explains how to seamlessly upgrade and onboard an existing Cisco Routing device into the Cisco SD-WAN infrastructure.

SD-Routing License Management

This release introduces license management support for SD-Routing devices. The supported licensing workflows include license assignment or configuration, license use, and license usage reporting. Depending on the device, these workflows are performed in the Cisco Catalyst SD-WAN Manager or on the device.
