Description |
|
Support for deployment of Catalyst 8000V in Oracle Cloud Infrastructure |
Oracle Cloud Infrastructure (OCI) is a cloud service that enables you to build and run a range of applications and services in a hosted environment. OCI provides high-performance compute capabilities as physical hardware instances and storage capacity in a flexible overlay virtual network that is securely accessible from your on-premises network. From Cisco IOS XE 17.18.1a release, Cisco Catalyst 8000V is supported for deployments in OCI on VM.Standard.E5.Flex compute instances for Bring Your Own License (BYOL) consumption. |

||
| Software Reliability |
Throughput performance optimizations |
From Cisco IOS XE 17.18.1a release, Cisco Catalyst 8000V delivers higher throughputs for both encrypted and unencrypted traffic. We recommend you benchmark your unique traffic profiles prior to production. The performance improvements will depend on your feature set, packet sizes, and the number of vCPU cores. |
|
| Licensing Process
|
Licensing compliance, reporting, and notification enhancements
|
From Cisco IOS XE 17.18.1a release, you can view additional information in your licensing report such as out of compliance and the reason for out of compliance, the number of licenses that have been assigned in the network, how many devices have been assigned licenses, per-device license details, and so on. In addition, you can now connect to the Enterprise Agreement (EA) portal directly from the Cisco SD-WAN Manager with your Smart Account credentials. This helps you to generate the required quantities of licenses for the selected Commerce SKU of EA and deposit them to your desired CSSM Virtual Accounts (VA). |
|
|
Ease of Use
|
From Cisco IOS XE 17.18.1a release, Cisco Catalyst SD-WAN Manager supports deployment of IOx applications such as Cyber Vision, Thousand Eyes, UTD, and so on. The support to monitor these applications is introduced through Hosted Edge Services monitoring dashboard which offers a simplified user experience for overseeing IOx container applications across multiple devices. The Hosted Edge Services monitoring dashboard is introduced on Cisco Catalyst SD-WAN Manager version 20.18.x. |
|
|
Ease of use
|
Security Cloud Control (SCC) is a cloud-based multi-device manager that facilitates management of security policies to achieve consistent policy implementation. SCC helps optimize your security policies by identifying inconsistencies with them and by giving you tools to fix the inconsistencies. From Cisco IOS XE 17.18.1a release, you can integrate Cisco SD-WAN Manager with SCC, which allows you to import existing NGFW policies, security objects, and security profiles into SCC. With this integration, you can share objects and policies as well as make configuration templates to promote policy consistency across devices. |
|
|
Security
|
From Cisco IOS XE 17.18.1a release, Custom IPS signature sets are supported in Cisco SD-WAN Manager, which allows you to create and deploy personalized Snort3 IPS signature sets. This feature allows direct modification of actions for existing IPS rules within profiles and supports building custom rules using rule groups or existing rules. With Custom IPS signature sets, organizations can gain greater control and precision in tailoring threat detection to their specific security needs. |
|
|
Ease of Use
|
This feature introduces a new certificate authorization setting, Enterprise Certificate Settings, which unifies certificate configurations for SD-Routing devices. Cisco SD-WAN Manager automates certificate management by leveraging protocols like EST (Enrolment over Secure Transport) and SCEP (Simple Certificate Enrolment Protocol). The feature automates the enrolment, and renewal of certificates. |
|
|
Upgrade
|
This feature enables the transport of IPv4 MVPN traffic across an SRv6 network. It simplifies multicast deployment by using the existing SRv6 unicast infrastructure as the underlay. With this feature, the ingress PE router receives multicast traffic and creates a separate unicast SRv6-encapsulated copy for each egress PE router in the multicast group. |
|
|
Upgrade
|
This feature introduces a mechanism to determine the maximum transmission unit (MTU) for packets traversing an SRv6 underlay network. It ensures efficient packet forwarding by preventing fragmentation and packet drops, thereby allowing network devices to dynamically adjust packet sizes to avoid exceeding link MTU limits. The system relays ICMP Packet Too Big (PTB) messages from the SRv6 underlay to the IPv6/IPv4 overlay network, supporting both Transit-node and Headend-node PTB relay methods. |
|
|
Upgrade
|
From Cisco IOS XE 17.18.1a, Flexible Algorithm enhances SRv6 by including functions like Topology Independent Loop-Free Alternate (TI-LFA) and microloop (uLoop) avoidance. This feature improves network resilience and efficiency. |
|
|
Upgrade
|
This feature enables the transport of IPv4 MVPN traffic across an SRv6 network. It simplifies multicast deployment by using the existing SRv6 unicast infrastructure as the underlay. With this feature, the ingress PE router receives multicast traffic and creates a separate unicast SRv6-encapsulated copy for each egress PE router in the multicast group. |

Product Analytics for routers |
Product Analytics refers to the collection of product telemetry such as product performance and resource usage information directly from IOS-XE-based routing platforms. From Cisco IOS XE 17.18.1a release, Product Analytics is enabled by default when. Use this functionality to gain data insights such as product performance, feature consumption, and the licensing types that suit your requirements best. |

|
Upgrade |
Third-Party GUID capture for correlation between call transfers and SIP-based recording |
From Cisco IOS XE 17.18.1a onwards, the Third-Party GUID capture for correlation between calls and SIP-based recording is extended to support transmission of globally unique identifiers (GUIDs) to the recording server during call transfers. |
|
