 Note |
For more information on the features and specifications of Cisco ASR 1000 Series Routers, refer to the Cisco ASR 1000 Series Routers datasheet. For information on the End-of-Life and End-of-Sale Announcements for Cisco ASR 1000 Series routers, refer to the ASR 1000 Series End-of-Life and End-of-Sale Notices. |
Note |
Cisco IOS XE Bengaluru 17.6.1a is the first release for Cisco ASR 1000 Series Aggregation Services Routers in the Cisco IOS XE Bengaluru 17.6.x release series. |
Note |
Starting from IOS XE 17.5, the following consolidated platforms (or with dual IOSd ) will move to monolith packaging and therefore it will not be possible to upgrade/downgrade using separate packages.
|
Instead use the command install add file bootflash:<file name> activate commit command to upgrade using a single image that combines all the separate packages therefore improving 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 17.6.1a, the following items will be disabled:
|
Note |
Starting with Cisco IOS XE 17.3.x, 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:

Description |
|---|---|
|
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 includes the following enhancements
|
|
|
This enhancement introduces commands that let you configure increase scaling of neighbors in a hub and spoke deployment using the following criterions
|
|
|
|
|
This feature supports configuring IEEE802.1ad on port-channel, port-channel subinterfaces and port-channel member links with configurable ethertypes, in addition to configuration on physical interfaces. |
|
| L2VPN Traffic SteeringUsing SR-TE Preferred Path |
This feature allows you to configure an SR policy as the preferred path for a VPWS or VPLS pseudowire. VPWS or VPLS pseudowires between same PEs can be routed over different SR policies based on the requirements. |
|
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. |
|
|
|
The Secure Factory Reset feature introduces the factory-reset secure all command that you can use to erase the contents of the bootflash memory, and securely reset the device using 3-pass overwrite method. |
|
|
The Zone-Based Firewall (ZBFW) Reclassification feature is an enhancement to the Zone-Based Firewall feature. With this enhancement, any changes you make to the policy configuration on an existing firewall session is immediately enforced. |
|
|
YANG models were developed for the following CLIs as part of the Class of Restriction configuration:

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. |
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. |
