Note


Cisco 4461 ISR may require two upgrade packages to upgrade to 21102941. See CPLD-4-1 Release Notes.

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 Navigator

You can use Cisco Feature Navigator to find information about feature, platform, and software image support. To access Cisco Feature Navigator, go to https://cfnng.cisco.com/. An account on cisco.com is not required.

Feature

Description

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.

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.

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. This feature is only supported on ISR4461.

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.

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.

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.

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.

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.

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.
