The Cisco 1000 Series Integrated Services Routers (also referred to as router in this document) are powerful fixed branch routers based on the Cisco IOS XE operating system. They are multi-core routers with separate core for data plane and control plane. There are two primary models with 8 LAN ports and 4 LAN ports. Features such as Smart Licensing, VDSL2 and ADSL2/2+, 802.11ac with Wave 2, 4G LTE-Advanced and 3G/4G LTE and LTEA Omnidirectional Dipole Antenna (LTE-ANTM-SMA-D) are supported on the router.
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:

New and Changed Hardware and Software Features
New and Changed Software Features

Cisco IOS XE Bengaluru 17.6.1a is the first release for Cisco 1000 Series Integrated Services Routers in the Cisco IOS XE Bengaluru 17.6.x release series. |

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. |

CFM operation and action model |
This feature introduces a NETCONF/YANG model to perform the following functions:
|
|
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. |
|
|
This feature lets you configure system reports that can provide critical information on issues that cause software crashes. |
|
|
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 1000 Series Integrated Services Routers. Instead of tagging licenses according to a router model (for example, ISR_1100_8P_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. |
|
YANG models were developed for the following CLIs as part of the Class of Restriction configuration:
|
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. |
