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 Cupertino 17.9.1a is the first release for Cisco ASR 1000 Series Aggregation Services Routers in the Cisco IOS XE Cupertino 17.9.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:

New and Changed Software Features for Cisco IOS XE 17.9.1a
Feature |
Description |
||
---|---|---|---|
This feature allows you to manage or change the lease renewal in a shorter period of time than the actual lease that is granted by the DHCP server. You can enable this using the ip dhcp relay short lease command on the server or relay agent. |
|||
The show isis node command is updated to display information about link and prefix cache, and the show isis lspgen tlv neighbor command is introduced to display information about ISIS LSP TLV neighbors. |
|||
Increase ACE Scale Limit Per OGACL |
This feature provides an increase in the ACE scale limit per ACL and OGACL as the current implementation of CACE has a total limit of only 64K entries. The scale for this feature is 1D and the scale information for OGACL is 3000 ACE entries per OGACL, 2400 OGs and 100 networks per OG. |
||
The ip nat settings log-destination command is introduced in Carrier Grade Network Address Translation (CGN) mode to include the destination IP address and the destination port details in the add and delete HSL records. |
|||
Support for BGP additional paths with label-unicast unique mode |
This enhancement introduces support for configuring BGP additional paths when label-unicast unique mode is configured. |
||
Previously, a separate PDP policy was created for every default IGP/RIB learned path. This implementation would eventually increase the number of policies and would not scale. From Cisco IOS XE 17.9.1, RIB path is supported for PFP. This feature enables you to configure forwarding class in a per flow policy using the RIB path option. Instead of configuring a per destination policy, the RIB option uses the IGP shortest path to the policy destination. |
|||
This feature introduces support for configuration of unicast-to-multicast destination reflection to facilitate unicast-to-multicast destination translation and unicast-to-multicast destination splitting. It also provides the capability for users to translate externally received unicast destination addresses to multicast addresses. |
|||
Cisco Unified Border Element (CUBE) Features |
|||
CUBE: End-to-end Secure Calling for Courtesy Call Back and Unified Contact Center Survivability |
With the Cisco Voice Portal (CVP) application, a caller may request an automatedcallback, rather than wait in a queue for an extended period. When an agent becomes available, CVP sends a request to place a call to the original caller. When the call is answered, the agent is connected. With this update, outbound calls over a secure SIP PSTN trunk are possible. |
||
This enhancement to the DNS session target feature, provides effective call distribution and load balancing of calls based on the preference, priority and availability of hosts provided in DNS SRV Resource Records. This feature further simplifies configuration by allowing effective call distribution with a single dial-peer. |
|||
Previously, CUBE (Local Gateway) had to be configured with separate dial-peers to monitor the availability of individual proxies used in services such as Webex Calling. To simplify this configuration, all targets resolved from a DNS SRV record may now be monitored using a common Options Ping policy defined for a single dial-peer. If a remote server becomes unresponsive, CUBE will busy out that destination, allowing calls to be sent to alternative destinations. |
|||
Cisco IOS gateways can use FTP and now SFTP servers to transfer call accounting files. |
|||
Programmability Feature |
|||
Pubd Restartability |
The pubd process is restartable on all platforms in this release. Prior to this release, pubd was restartable only on certain platforms. On other platforms, to restart the pubd process, the whole device had to be restarted. |
||
Smart Licensing Using Policy Features |
|||
New mechanism to send data privacy related information |
A new mechanism to send data privacy related information was introduced. This information is no longer included in a RUM report. If data privacy is disabled (no license smart privacy{all|hostname|version} command in global configuration mode), data privacy related information is sent in a separate sync message or offline file. Depending on the topology you have implemented, the product instance initiates the sending of this information in a separate message, or CSLU and SSM On-Prem initiates the retrieval of this information from the product instance, or this information is saved in an offline file. For more information, see license smart (global config). |
||
Hostname support |
Support for sending hostname information was introduced. If you configure a hostname on the product instance and disable the corresponding privacy setting (no license smart privacy hostname command in global configuration mode), hostname information is sent from the product instance, in a separate sync message or offline file. Depending on the topology you have implemented, the hostname information is received by CSSM, CSLU, and SSM On-Prem. It is then displayed on the corresponding user interface. For more information, see license smart (global config).
|
||
RUM Report Throttling |
For all topologies where the product instance initiates communication, the minimum reporting frequency is throttled to one day. This means the product instance does not send more than one RUM report a day. The affected topologies are: Connected Directly to CSSM, Connected to CSSM Through CSLU (product instance-initiated communication), CSLU Disconnected from CSSM (product instance-initiated communication), and SSM On-Prem Deployment (product instance-initiated communication). This resolves the problem of too many RUM reports being generated and sent for certain licenses. It also resolves the memory-related issues and system slow-down that was caused by an excessive generation of RUM reports. You can override the reporting frequency throttling, by entering the license smart sync command in privileged EXEC mode. This triggers an on-demand synchronization with CSSM or CSLU, or SSM On-Prem, to send and receive any pending data. RUM report throttling also applies to the Cisco IOS XE Amsterdam 17.3.6 and later releases of the 17.3.x train, and Cisco IOS XE Bengaluru 17.6.4 and later releases of the 17.6.x train. From Cisco IOS XE Cupertino 17.9.1, RUM report throttling is applicable to all subsequent releases. |
||
Virtual Routing and Forwarding (VRF) Support |
On a product instance where VRF is supported, you can configure the license smart vrf vrf_string command and use a VRF to send licensing data to CSSM, or CSLU, or SSM On-Prem.
