About Cisco 1000 Series Integrated Services Routers
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 |
Cisco IOS XE Dublin 17.10.1a is the first release for Cisco 1000 Series Integrated Services Routers in the Cisco IOS XE Dublin 17.10.x release series. |
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.
New and Changed Hardware and Software Features
New and Changed Software Features

Feature |
Discription |
|---|---|
|
This feature provides the ip dhcp client vendor-class command that helps you configure the dhcp client to carry option 124 data in DHCPv4 along with the interface MAC address or user-defined string. When the option 124 data in DHCPv4 is disabled, it disables sending the option 124 in DHCPv4 messages. By default, the DHCPv4 client sends device PID as the value for option 124. |
|
|
This feature provides the ipv6 dhcp client vendor-class command that helps you configure the DHCPv6 client to carry option 16 data in DHCPv6 along with the interface MAC address or user-defined string. When the option 16 data in DHCPv6 is disabled, it disables sending the option 16 in DHCPv6 messages. By default, the DHCPv6 client sends device PID as the value for option 16. |
|
|
Using this feature you can configure to match the packets based on user defined field position and length. This can be used by an ACL to match packets that cannot be classified easily with the traditional Layer 3 and Layer 4 field information. |
|
|
The 5G sub-6 GHz Pluggable Interface Module (PIM) P-5GS6-GL is supported on the Cisco 1000 Series Integrated Services Routers. |
|
|
Support for YANG Operational Model in the GETVPN architecture |
This feature enables the YANG operational model in the GETVPN architecture to support the crypto gdoi command which was previously enabled only for the CLI and SNMP models. |
|
Additional YANG configuration models are included in this release to enable Unified SRST secure calling, applications for CUBE, and additional codecs for voice class codec lists. |
Note |
From Cisco IOS XE Release 17.9.1a, guestshell is removed from the IOS XE software image. As a result, Zero Touch Provisioning (ZTP) python script is no longer supported on Cisco 1000 Series Integrated Services Routers. If you need to use guestshell, then download it from https://developer.cisco.com/docs/iox/#!iox-resource-downloads/downloads. For more information, see Guestshell installation procedure. |
