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.

Feature |
Description |
|---|---|
|
This feature allows you to manage or change the lease renewal. It provides options to force renewal of lease and also detects when the lease is nearing the expiry date. |
|
|
CFM Operation and Action Command Support |
This feature introduces a NETCONF/YANG model to perform the following functions:
This model helps you to gain more visibility into the timing of the services operations and manage network devices from a centralised orchestration application such as Cisco DNAC. For more information, see the Programmability Configuration Guide. |
|
Cisco ThousandEyes application is a cloud-ready, enterprise network-monitoring tool that provides an end-to-end view across networks and services. This tool helps in analyzing the network performance and provides insights into the Internet and enterprise networks. |
|
|
From Cisco IOS XE 17.6.1 onwards, CUBE can transcode OPUS encoded media streams. Because Opus codecs perform very well over the Internet, this feature is particularly beneficial when routing calls between the PSTN and Cloud calling services. |
|
|
This feature lets you configure system reports that can provide critical information on issues that cause software crashes. |
|
|
This feature allows you to configure an SR policy as the preferred path for a Virtual Private Wire Service (VPWS) or Virtual Private LAN Service (VPLS) pseudowire. VPWS or VPLS pseudowires between same PEs can be routed over different SR policies based on the requirements. |
|
|
Phasing Out of Device-Specific HSECK9 Licenses |
With the introduction of Cisco Digital Network Architecture (Cisco DNA), there is a change in the entitlement tags for HSECK9 licenses supported on Cisco 4000 Series Integrated Services Routers. Instead of tagging licenses according to a router model (for example, ISR_4331_Hsec), HSECK9 licenses are tagged as Router US Export Lic for DNA (DNA_HSEC). Starting with this release, if you want to purchase new HSECK9 licenses for these products, we recommend that you buy only DNA_HSEC. If the software version running on the product instance is Cisco IOS XE Bengaluru 17.6.1a or later, it has the following implications:
For more information, see Phasing Out of Device-Specific HSECK9 Licenses. |
|
The PPPoE Client over VLAN interface enhancement allows you to configure the PPPoE client to establish a PPPoE session over a VLAN interface. |
|
|
Pyang version 2.x |
The updated pyang plugin version 2.x fixes existing issues such as XPATH validation and upstream pyang issues. Additionally, this version reports all errors in the YANG models to the users and enforces a strict model validation. |
|
This feature allows you to leak (or replicate) routes between the global VRF and service VPNs, and redistribute the leaked routes into the destination protocol BGP. The redistribution of the leaked routes occurs after replicating the routes into the corresponding VRF. Route leaking allows you to share common services that multiple VPNs need to access. The source protocols that support route leaking and redistribution of routes into the destination protocol BGP are as follows:
|
|
|
YANG models were developed for the following CLIs as part of the Class of Restriction configuration:
|
|
|
The Zone-Based Firewall (ZBFW) Reclassification feature is an enhancement to the Zone-Based Firewall feature. With this enhancement, any changes you make to the policy configuration on an existing firewall session is immediately enforced. |
|
Feature |
Description |
|---|---|
|
Snapshots for PAK Licenses |
The library that manages product activation key (PAK) licenses is being deprecated from the software image. To continue supporting and honouring any existing PAK licenses you may have, the system automatically takes a snapshot of the PAK license and triggers a Device-Led Conversion process, to convert the PAK license to a Smart License. For the system to take the snapshot, the software version running on your device must be one of the required releases. For information about the releases in which the system can take a snapshot, and the options that are available with respect to the device and the license, see Snapshots for PAK Licenses. |
Note |
From Cisco IOS XE Bengaluru 17.6.x, configuring a weak crypto algorithm generates a warning message. However, you can ignore this warning because the working of crypto algorithms is not impacted. For more information on weak crypto algorithms, see Supported Standards. |
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.
