Cisco 4000 Series Integrated Services Routers Overview
 Note |
Cisco IOS XE Dublin 17.12.1a is the first release for Cisco 4000 Series Integrated Services Routers in the Cisco IOS XE 17.12.x release series. |
The Cisco 4000 Series ISRs are modular routers with LAN and WAN connections that can be configured by means of interface modules, including Cisco Enhanced Service Modules (SM-Xs), and Network Interface Modules (NIMs).
Note |
Starting with Cisco IOS XE Amsterdam 17.3.2 release, with the introduction of Smart Licensing Using Policy, even if you configure a hostname for a product instance or device, only the Unique Device Identifier (UDI) is displayed. This change in the display can be observed in all licensing utilities and user interfaces where the hostname was displayed in earlier releases. It does not affect any licensing functionality. There is no workaround for this limitation. The licensing utilities and user interfaces that are affected by this limitation include only the following:

Product Field Notice
Cisco publishes Field Notices to notify customers and partners about significant issues in Cisco products that typically require an upgrade, workaround or other user action. For more information, see https://www.cisco.com/c/en/us/support/web/field-notice-overview.html.
We recommend that you review the field notices to determine whether your software or hardware platforms are affected. You can access the field notices from https://www.cisco.com/c/en/us/support/web/tsd-products-field-notice-summary.html#%7Etab-product-categories.
System Requirements
The following are the minimum system requirements:
Note |
There is no change in the system requirements from the earlier releases. |
-
Memory: 4 GB DDR3 up to 32 GB
-
Hard Drive: 200 GB or higher (Optional). The hard drive is only required for running services such as Cisco ISR-WAAS.
-
Flash Storage: 4 GB to 32 GB
-
NIMs and SM-Xs: Modules (Optional)
-
NIM SSD (Optional)
For more information, see the Cisco 4000 Series ISRs Data Sheet.
Note |
For more information on the Cisco WAAS IOS-XE interoperability, see the WAAS Release Notes: https://www.cisco.com/c/en/us/support/routers/wide-area-application-services-waas-software/products-release-notes-list.html. |
Determining the Software Version
You can use the following commands to verify your software version:
-
For a consolidated package, use the show version command
-
For individual sub-packages, use the show version installed command
Upgrading to a New Software Release
To install or upgrade, obtain a Cisco IOS XE 17.12.x consolidated package (image) from Cisco.com. You can find software images at http://software.cisco.com/download/navigator.html. To run the router using individual sub-packages, you also must first download the consolidated package and extract the individual sub-packages from a consolidated package.
Note |
When you upgrade from one Cisco IOS XE release to another, you may see %Invalid IPV6 address error in the console log file. To rectify this error, enter global configuration mode, and re-enter the missing IPv6 alias commands and save the configuration. The commands will be persistent on subsequent reloads. |
For more information on upgrading the software, see the Installing the Software section of the Software Configuration Guide for the Cisco 4000 Series ISRs.

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.

|---|---|---|---|---|---|
|
The Managed Cellular Activation solution provides a programmable subscriber identity module (SIM), called an eSIM, a physical SIM card that you can configure with a cellular service plan of your choice. When ordering a pluggable interface module (PIM) to provide cellular connectivity for your router, choose a PIM model with a preinstalled eSIM. The Managed Cellular Activation solution comes with a “bootstrap” cellular plan to provide internet connectivity with a limited amount of data intended only for Day 0 onboarding of the device to your cellular plan. For information about configuring Cisco SD-WAN Manager with the details of your cellular plan in preparation for onboarding the device, see the Cisco Managed Cellular Activation Configuration Guide. Prepare the configuration in Cisco SD-WAN Manager before powering on and onboarding the device, to avoid running out of the limited data in the bootstrap cellular plan. Added Cisco Managed Cellular Activation (eSIM) support for the following Pluggable Interface Module (PIM) model:

|
This feature allows you to perform management operations for SD-Routing devices using Cisco Catalyst SD-WAN Manager. You can use a single network manage system (Cisco Catalyst SD-WAN Manager) to monitor all the SD-Routing devices and therefore help in simplifying solution deployments. |
||
|
This feature allows you to delete the entries from the logging buffer. You can configure the local syslog retention period after which the entries are purged from the device automatically. To enable this feature, use the logging purge-log buffer days command. |
||
|
This feature introduces the factory-reset all secure command for Cisco 4000 Series ISRs. From Cisco IOS XE 17.12.1a, you can use the factory-reset all secure command to securely clear all the data in bootflash, hard disk, and ROMMONs. |

From Cisco IOS XE Dublin 17.12.1a onwards, High Availability in CUBE supports IPv6 flows. |
||
|
From Cisco IOS XE Dublin 17.12.1a onwards, VoIP Trace for SIP messages displays cause code in the cover buffer. |

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.
Resolved and Open Bugs
This section provides information about the bugs in Cisco 4000 Series Integrated Services Routers and describe unexpected behavior. Severity 1 bugs are the most serious bugs. Severity 2 bugs are less serious. Severity 3 bugs are moderate bugs. This section includes severity 1, severity 2, and selected severity 3 bugs.
The open and resolved bugs for this release are accessible through the Cisco Bug Search Tool. This web-based tool provides you with access to the Cisco bug tracking system, which maintains information about bugs and vulnerabilities in this product and other Cisco hardware and software products. Within the Cisco Bug Search Tool, each bug is given a unique identifier (ID) with a pattern of CSCxxNNNNN, where x is any letter (a-z) and N is any number (0-9). The bug IDs are frequently referenced in Cisco documentation, such as Security Advisories, Field Notices and other Cisco support documents. Technical Assistance Center (TAC) engineers or other Cisco staff can also provide you with the ID for a specific bug. The Cisco Bug Search Tool enables you to filter the bugs so that you only see those in which you are interested.
In addition to being able to search for a specific bug ID, or for all bugs in a product and release, you can filter the open and/or resolved bugs by one or more of the following criteria:
-
Last modified date
-
Status, such as fixed (resolved) or open
-
Severity
-
Support cases
You can save searches that you perform frequently. You can also bookmark the URL for a search and email the URL for those search results.
Note |
If the bug that you have requested cannot be displayed, this may be due to one or more of the following reasons: the bug ID does not exist, the bug does not have a customer-visible description yet, or the bug has been marked Cisco Confidential. |
