New and Changed Software Features in Cisco IOS XE 17.15.1a
|
Feature |
Description |
|---|---|
|
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: |
|
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. |
|
|
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. |
|
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. |
|
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. |
|
|
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 (NWPI) is a tool that allows network administrators to monitor Cisco SD-Routing deployment, identify network and application issues, and optimize the network. |
|
|
This feature explains how to seamlessly upgrade and onboard an existing Cisco Routing device into the Cisco SD-WAN infrastructure. |
|
|
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. |
|
|
This feature provides support for including Cisco IOS XE CLI configuration commands that do not have an associated yang model. When used with the current configuration group, Classic CLI provides a robust provisioning mechanism for SD-Routing devices from Cisco SD-WAN Manager. |

Upgrade ROMmon
To upgrade the ROMmon version of your device, use these steps:
-
Check the existing version of ROMmon by using show rom-monitor r0 command. If you are installing Cisco IOS XE software on a new device, skip this step.
-
Review Minimum and Recommended ROMmon Releases to identify the recommended version of ROMmon software for the device you plan to upgrade.
-
Go to https://software.cisco.com/# and download the ROMmon package file.
-
Copy the ROMmon file to flash drive:
copyftp:// username:password@IP addressROMmon package file flash: -
Upgrade the ROMmon package using the following command:
upgrade rom-monitor filename bootflash: ROMmon package name all -
Execute reload command to complete the ROMmon upgrade process
-
