Upgrading Field-Programmable Hardware Devices
The hardware-programmable firmware is upgraded when Cisco 4000 Series ISR contains an incompatible version of the hardware-programmable firmware. To do this upgrade, a hardware-programmable firmware package is released to customers.
Generally, an upgrade is necessary only when a system message indicates one of the field-programmable devices on the Cisco 4000 Series ISR needs an upgrade, or a Cisco technical support representative suggests an upgrade.
From Cisco IOS XE Release 3.10S onwards, you must upgrade the CPLD firmware to support the incompatible versions of the firmware on the Cisco 4000 Series ISR. For upgrade procedures, see the Upgrading Field-Programmable Hardware Devices for Cisco 4000 Series ISRs.

New and Changed Information
New and Changed Hardware Features
There are no new hardware features for this release.
New and Changed Software Features
Feature |
Description |
|
---|---|---|
The Application Performance Monitor feature introduces a simplified framework that enables you to configure intent-based performance monitors. With this framework, you can view real-time, end-to-end application performance filtered by client segments, network segments, and server segments. |
||
Cisco SD-Routing Cloud OnRamp for Multicloud extends enterprise WAN to public clouds. This multicloud solution helps to integrate public cloud infrastructure into the Cisco Catalyst SD-Routing devices. With these capabilities, the devices can access the applications hosted in the cloud. |
||
|
||
This feature introduces support for configuring retry time intervals for GARP messages on the BD-VIF interface. You can configure this feature using the global ip arp nat-garp-retry and ip nat inside source static commands. |
||
With this feature, you can schedule software image upgrade on Cisco SD-Routing devices. This allows you to avoid any downtime due to the software upgrade process. |
||
The Configuration Group feature provides a simple, reusable, and structured method to configure the SD-Routing device using Cisco Catalyst SD-WAN Manager. |
||
Cisco SD-WAN Manager allows you to measure the network speed and available bandwidth between a device and an iPerf3 server. The speed tests measure upload speed from the source device to the selected or specified iPerf3 server, and measure download speed from the iPerf3 server to the source device. |
||
This feature introduces an algorithm to ensure that the strength of the IKE (IKEv1 and IKEv2) SA encryption cipher is greater than or equal to the strength of its child IPsec SA encryption cipher. To enable this algorithm, use the crypto ipsec ike sa-strength-enforcement command. |
||
Support for Flexible NetFlow Application Visibility on SD-Routing Devices |
The Flexible NetFlow (FNF) feature provides statistics on packets flowing through the device and helps to identify the tunnel or service VPNs. Also, it provides visibility for all the traffic that passes through the VPN0 on Cisco SD-Routing devices by using the SD-Routing Application Intelligence Engine (SAIE). |
|
This feature allows you to configure options to capture the bidirectional IPv6 traffic data to troubleshoot connectivity on the SD-Routing devices. |
||
From IOS XE 17.13.1a, the device maintains the neighbor information even after the session is terminated. To configure this, use the bgp listen persistent command for all dynamic neighbors and bgp listen range peer-group persistent command for specific neighbors. |
||
SELinux (Security-Enhanced Linux) is a solution designed to incorporate a strong, flexible mandatory access control (MAC) architecture into Cisco IOS XE platforms. From Cisco IOS XE 17.13.1a, SELinux is enabled by default in Enforcing mode for Cisco IOS XE platforms. |
||
Cisco Unified Border Element (CUBE) Features |
||
From Cisco IOS XE 17.13.1a onwards, using RTP keepalive packets, CUBE supports media transmission in the NAT environment. |
Configure the Router for Web User Interface
This section explains how to configure the router to access Web User Interface. Web User Interface requires the following basic configuration to connect to the router and manage it.
-
An HTTP or HTTPs server must be enabled with local authentication.
-
A local user account with privilege level 15 and accompanying password must be configured.
-
Vty line with protocol SSH/Telnet must be enabled with local authentication. This is needed for interactive commands.
-
For more information on how to configure the router for Web User Interface, see Cisco 4000 Series ISRs Software Configuration Guide, Cisco IOS XE 17.
