Note |
Cisco IOS XE Cupertino 17.7.1a is the first release for Cisco ASR 1000 Series Aggregation Services Routers in the Cisco IOS XE Cupertino 17.7.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.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:

New and Changed Software Features
|
Feature |
Description |
||
|---|---|---|---|
|
This feature introduces new methods of attaching extended color communities to a prefix. A color community is an indicator of the bandwidth or latency level of the traffic being sent to the prefix and these are following new ways of attaching them to the prefix: VRF export coloring, VRF import coloring, Route Redistribution coloring into BGP and Neighbor inbound coloring. |
|||
|
This enhancement allows you to configure an EVPN-VPWS over a preferred path using SR-TE policy. The command preferred-path segment-routing traffic-eng policy includes the fallback disable option, which allows you to configure fallback behaviour. |
|||
|
This feature introduces Flexible NetFlow (FNF) support on Bridge Domain Virtual IP Interfaces (BD-VIF). Flexible Netflow provides improved optimization and performance, enhanced security, and increased flexibility and scalability to the network. You can configure FNF on a BD-VIF using the ip flow monitor command. |
|||
|
The show ip multicast overlay-mapping command displays an underlay group address from the overlay group address which is used to troubleshoot or configure the network. The output includes the underlay group address that is within the configured SSM (Source Specific Multicast) address range. |
|||
|
Autoroute announcement is a method to steer traffic away from congested links and therefore, helps to use the network efficiently. This enhancement provides ISIS as an alternative routing protocol for the autoroute announce feature that currently uses only OSPF. |
|||
|
This feature enables redundant network connectivity via Multihoming by allowing a CE device to connect to more than one PE device therefore preventing disruptions in the network. This Multihoming IRB solution is supported on Cisco ASR 1000 routers through the following features:
|
|||
|
Tunnel protection for IPIP with NAT-T |
When you configure the tunnel protection on an IPIP tunnel, the NAT-T configuration on the IPsec tunnel works as expected. However, the incoming packets are not processed though the Internet Security Association and Key Management Protocol and IPsec Security Association are correctly generated. To ensure that the tunnel protection on the IPIP tunnel works seamlessly, configure the tunnel mode GRE IP on both endpoints. |
||
|
This feature introduces VLAN manual load balancing on port-channel Q-in-Q interfaces using the encapsulation dot1q second-dot1q primary secondary command. Using this command, you can manually assign VLAN subinterfaces to primary and secondary Gigabit Ethernet Channel member links, and direct traffic flows to a particular subinterface bucket with the load-balancing algorithm. |
|||
|
Cisco Unified Border Element (CUBE) Features |
|||
|
From IOS-XE Cupertino-17.7.1a, YANG models are now available to configure and manage CUBE. |
|||
|
YANG Model Version 1.1 |
Cisco IOS XE Cupertino 17.7.1a uses the YANG version 1.0; however, you can download the YANG version 1.1 from GitHub at https://github.com/YangModels/yang/tree/master/vendor/cisco/xe folder. For inquiries related to the migrate_yang_version.py script or the Cisco IOS XE YANG migration process, send an email to xe-yang-migration@cisco.com. |
||
|
ZTP Configuration through YANG |
ZTP is enabled through YANG models when NETCONF is enabled. |
||
|
Programmability Features |
|||
|
Converting IOS Commands to XML |
This feature helps to automatically translate IOS commands into relevant NETCONF-XML or RESTCONF/JSON request messages. |
||
|
Smart Licensing Using Policy Features |
|||
|
Ability to save authorization code request and return in a file and simpler upload in the CSSM Web UI |
If your product instance is in an air-gapped network, you can now save an SLAC request in a file on the product instance. The SLAC request file must be uploaded to the CSSM Web UI. You can then download the file containing the SLAC code and install it on the product instance. You can also upload a return request file in a similar manner. With this new method you do not have to gather and enter the required details on the CSSM Web UI to generate an SLAC. You also do not have to locate the product instance in the CSSM Web UI to return an authorization code. In the CSSM Web UI, you must upload the SLAC request or return file in the same way as you upload a RUM report. In the required Smart Account, navigate to Reports → Usage Data Files. See: No Connectivity to CSSM and No CSLU, Workflow for Topology: No Connectivity to CSSM and No CSLU, Saving a SLAC Request on the Product Instance, Removing and Returning an Authorization Code, Uploading Data or Requests to CSSM and Downloading a File |
||
|
Account information included in the ACK and show command outputs |
A RUM acknowledgement (ACK) includes the Smart Account and Virtual Account that was reported to, in CSSM. You can then display account information using various show commands. The account information that is displayed is always as per the latest available ACK on the product instance. See: show license summary, show license status, show license tech. |
||
|
CSLU support for Linux |
CSLU can now be deployed on a machine (laptop or desktop) running Linux. See: CSLU, Workflow for Topology: Connected to CSSM Through CSLU, Workflow for Topology: CSLU Disconnected from CSSM. |
||
|
Factory-installed trust code |
For new hardware and software orders, a trust code is now installed at the time of manufacturing.
|
||
|
RUM Report optimization and availability of statistics |
RUM report generation and related processes have been optimized. This includes a reduction in the time it takes to process RUM reports, better memory and disk space utilization, and visibility into the RUM reports on the product instance (how many there are, the processing state each one is in, if there are errors in any of them, and so on). See: RUM Report and Report Acknowledgement, Upgrades, Downgrades, show license rum, show license all, show license tech. |
||
|
Support for trust code in additional topologies |
A trust code is automatically obtained in topologies where the product instance initiates the sending of data to Cisco Smart License Utility (CSLU)and in topologies where the product instance is in an air-gapped network. See: Trust Code, Connected to CSSM Through CSLU, Tasks for Product Instance-Initiated Communication, CSLU Disconnected from CSSM, Tasks for Product Instance-Initiated Communication, No Connectivity to CSSM and No CSLU, Workflow for Topology: No Connectivity to CSSM and No CSLU. |
||
|
Support to collect software version in a RUM report |
If version privacy is disabled (no license smart privacy version global configuration command), the Cisco IOS-XE software version running on the product instance and the Smart Agent version information is included in the RUM report. |
||
