New and Changed Software Features in Cisco IOS XE 17.13.1a
|
Feature |
Description |
||
|---|---|---|---|
|
The Application Performance Monitor feature is a simplified framework that enables you to configure intent-based performance monitors. With this feature, you can view real-time, end-to-end application performance filtered by client segments, network segments, and server segments. |
|||
|
Cisco SD-Routing Cloud OnRamp for Multicloud extends enterprise WAN to public clouds. This multicloud solution helps to integrate public cloud infrastructure into the Cisco Catalyst SD-Routing devices. With these capabilities, the devices can access the applications hosted in the cloud. |
|||
|
From Cisco IOS XE 17.13.1a, you can disable multi-part TLVs for prefix-reachability, router capability, and (MT)IS-Neighbor in ISIS by using the multi-part-tlv disable command. |
|||
|
|||
|
This feature introduces support for configuring retry time intervals for GARP messages on the BD-VIF interface. You can configure this feature using the global ip arp nat-garp-retry and ip nat inside source static commands. |
|||
|
With this feature, you can upgrade the software image on the supported Cisco SD-Routing devices with an option to schedule the upgrade process at specified time. This allows you to avoid any downtime due to the software upgrade process. |
|||
|
The Configuration Group feature provides a simple, reusable, and structured method to configure the SD-Routing device using Cisco Catalyst SD-WAN Manager. |
|||
|
From Cisco IOS XE 17.13.1a, Segment Routing is supported over the IPv6 dataplane for Border Gateway Protocol (BGP) on L3VPN networks using On-Demand Next Hop (ODN). |
|||
|
Cisco SD-WAN Manager allows you to measure the network speed and available bandwidth between a device and an iPerf3 server. The speed tests measure upload speed from the source device to the selected or specified iPerf3 server, and measure download speed from the iPerf3 server to the source device. |
|||
| This feature ensures that the strength of the IKE (IKEv1 and IKEv2) SA encryption cipher is greater than or equal to the strength
of its child IPsec SA encryption cipher.
To enable this feature, use the crypto ipsec ike sa-strength-enforcement command. |
|||
|
Support for Flexible NetFlow Application Visibility on SD-Routing Devices |
The Flexible NetFlow (FNF) feature provides statistics on packets flowing through the device and helps to identify the tunnel or service VPNs. Also, it provides visibility for all the traffic that passes through the VPN0 on Cisco SD-Routing devices by using the Application Intelligence Engine (SAIE). |
||
|
This feature allows you to capture the bidirectional IPv6 traffic data to troubleshoot connectivity on the SD-Routing devices. |
|||
|
From IOS XE 17.13.1a, the device maintains the neighbor information even after the session is terminated. To configure this, use the bgp listen persistent command for all dynamic neighbors and bgp listen range peer-group persistent command for specific neighbors. |
|||
|
SELinux (Security-Enhanced Linux) is a solution designed to incorporate a strong, flexible mandatory access control (MAC) architecture into Cisco IOS XE platforms. From Cisco IOS XE 17.13.1a, SELinux is enabled by default in Enforcing mode for Cisco IOS XE platforms. |
|||
|
This enhancement introduces support for Suite B ciphers with GET VPN on the following router models:
|
|||
|
You can use the VRF-Aware Software Infrastructure Scale feature in the NTPv6 environment to support inter-VRF communication, such as access control lists (ACLs), Network Address Translation (NAT), policing, and zone-based firewalls, for MPLS traffic or IPv4 and IPv6 traffic flowing across two different Virtual Routing and Forwarding (VRF) instances. The VASI interfaces support redundancy of the Route Processor (RP) and Forwarding Processor (FP). |
|||
|
From Cisco IOS XE 17.13.1a, you can use the show drops history qfp command to view the history of the QFP drops on the Cisco ASR 1000 Series and Catalyst 8500 Series Edge Platforms. |
|||
| Cisco Unified Border Element (CUBE) Features | |||
|
From Cisco IOS XE 17.13.1a onwards, using RTP keepalive packets, CUBE supports media transmission in the NAT environment. |
|||
