Note |
Starting with Cisco IOS XE Amsterdam 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:

Sections in this documentation apply to all models of unless a reference to a specific model is made explicitly.
New and Changed Software Features
Note |
Starting from IOS XE 17.5, the following platforms 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. |
Note |
Starting from IOS XE 17.6, the ISSU on Cisco Catalyst 8500 Edge Platforms 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:
Additionally, dual IOSd ISSU commands and Bundle mode ISSU workflows will also be disabled. |
Feature |
Description |
---|---|
Traffic Steering by Dropping Invalid Paths | If the SR-TE Policy has no valid paths defined, the paths are dropped and traffic being steered through the policy falls back to the default (unconstrained IGP) forwarding path. Also, when a SR-TE policy carrying best-effort traffic fails, traffic is re-routed and this impacts the SLA for premium traffic.To solve this issue, if the SR-TE policy fails, the traffic in the data plane is dropped but kept in the control plane. Therefore, other SR policies, potentially carrying premium traffic, are not impacted. |
Enabling Segment Routing Flexible Algorithm with IS-IS |
|
View traffic counters for SR-TE policies | The existing command show segment-routing traffic-eng policy is improved to display the traffic rate on the tunnel interface. No configuration is required to enable this feature. |
This feature allows you to configure load balancing of outgoing traffic across all IGP ECMP paths proportionally to the interface bandwidth. |
|
This feature lets you configure a limit to the number of mroutes on an interface. By limiting the mroutes, you can avoid the risk of flooding the network with mroutes therefore protecting the router from resource overload and also preventing DoS attacks. |
|
You can now use the tunnel mpls-ip-only command to configure how the Do Not Fragment bit from the payload is copied into the tunnel packets IP header.If the Do Not Fragment bit is not set, the payload is fragmented if an IP packet exceeds the MTU set for the interface |

License Management for Smart Licensing Using Policy, Using Cisco vManage |
Cisco SD-WAN operates together with Cisco SSM to provide license management through Cisco vManage for devices operating with Cisco SD-WAN. For this you have to implement a topology where Cisco vManage is connected to CSSM. For information about this topology, see the Connected to CSSM Through a Controller, and to know how to implement it, see the Workflow for Topology: Connected to CSSM Through a Controller sections of the Smart Licensing Using Policy for Cisco Enterprise Routing Platformsguide. For more information about Cisco vManage, see the License Management for Smart Licensing Using Policy section of the Cisco SD-WAN Getting Start Guide. For a more detailed overview on Cisco Licensing, go to cisco.com/go/licensingguide. |
