Note |
Cisco IOS XE Dublin 17.10.1a is the first release for Cisco ASR 1000 Series Aggregation Services Routers in the Cisco IOS XE Dublin 17.10.x release series. |
Note |
Starting from IOS XE 17.5, the following consolidated platforms (or with dual IOSd) will move to monolith packaging and will not enable upgrade/downgrade using separate packages:
|
Instead, use the install add file bootflash:<file name> activate commit command to upgrade using a single image that combines all the separate packages improves the boot time.
Starting from IOS XE 17.6, the ISSU on Cisco ASR 1000 Series Aggregation Services Routers will migrate to an install workflow that provides step-by-step upgrade/downgrade commands.
The ISSU load version commands will be deprecated and these commands include:
-
abortversion
-
acceptversion
-
checkversion
-
commitversion
-
config-sync
-
image-version
-
loadversion
-
runversion.
Additionally, dual IOSd ISSU commands and Bundle mode ISSU workflows will also be disabled.
Note |
The In-Service Software Upgrade (ISSU) in ASR 1000 is being migrated to an install workflow that provides a step-by-step upgrade/downgrade. Starting from IOS-XE 17.6.1, the following items will be disabled:
|
Note |
Starting with Cisco IOS XE 17.3.2, 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 Software Features
|
Feature |
Discription |
|---|---|
|
Border Gateway Protocol (BGP) Ethernet VPN (EVPN) Virtual Extensible LAN (VXLAN) is a campus and data center network solution for Cisco devices that run on Cisco IOS XE software. This feature allows Layer 2 segments to be supported across an IP core therefore allowing improved scalability with infrastructure. It also provides all the benefits of Layer 3 topologies. |
|
|
This enhancement includes new filtering options for the show isis database command to support increased scale, view information on neighbours or prefixes and display both router capability information and raw TLV encoding. |
|
|
Segment Routing Absolute One-Way Link Loss Measurement for GRE-IPSec Tunnel |
This feature provides a mechanism for link loss measurement for point-to-point GRE-IPSec tunnel and identifies paths that meet specified loss criteria. |
|
This feature introduces support to enable stateful NAT64 translations with Carrier Grade NAT (CGN) enabled within Virtual routing and forwarding (VRF) instances in a network. |
|
|
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. |
|
Cisco Unified Border Element (CUBE) Features |
|
|
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. |
