Features Introduced in Prisma SD-WAN Release 6.5.2

Support for Layer 3 Loopback Interfaces

Layer 3 loopback interface is a powerful new feature for ION devices that provides a virtual interface that is always reachable for management and troubleshooting operations. With this feature you can configure an IP address that is not tied to a physical interface and enable services like SSH and Syslog without relying on physical LAN or WAN interfaces, which may be subject to customer infrastructure changes or security considerations.

The primary use case for L3 Loopback include management traffic segregation, SD-WAN tunnel establishment over non-routable MPLS WAN interfaces, and BGP routing protocol support.

Enhanced Link Aggregation and Port-Channel on ION 3200, ION 5200, and ION 9200 Devices

The Link Aggregation Group (LAG) and Link Aggregation Control Protocol (LACP), commonly called port-channel, are supported on Layer 3 ports on the LAN side. This new feature allows bundling multiple physical ports to increase bandwidth capacity, improve fault tolerance, and ensure high-speed communication. By incorporating LAG/LACP, Prisma SD-WAN demonstrates its unwavering commitment to providing customers with exceptional port resiliency and seamless, high-throughput data transmission.

Prisma SD-WAN supports this enhancement for data center ION devices.

Enhanced DNS Probing over Standard VPN

The Enable DNS Liveliness in Tunnel feature improves HTTP probe reliability in ION devices by performing DNS lookups directly over the Service Link tunnel instead of relying on WAN interface DNS servers. Previously, ION devices sent DNS requests to all interfaces and used the first response received, which could lead to incorrect probe targeting or failures due to misconfigured or unreachable DNS servers. With this enhancement, DNS resolution occurs over the service tunnel, ensuring more accurate and reliable HTTP probes while eliminating dependency on WAN interface DNS servers.

Support for App Acceleration

Application Acceleration is a powerful feature designed to enhance the performance of SaaS applications for Prisma SD-WAN users. This capability leverages the geographically distributed presence of Prisma SASE to optimize traffic between branch sites and SaaS destinations. The feature supports both standalone Prisma SD-WAN deployments and SASE configurations that include Prisma Access. When enabled, Application Acceleration performs packet loss optimization and can provide layer 4 and layer 7 acceleration for supported SaaS applications.

You can easily configure this functionality through performance policies, allowing granular control over the applications that benefit from acceleration. The solution also includes comprehensive visibility and monitoring tools to help you quantify the performance improvements and troubleshoot any issues. By implementing application acceleration, you can ensure your distributed workforce experiences consistent, high-quality access to essential SaaS resources, ultimately boosting productivity and satisfaction across your organization.

Device-ID Enforcement

Branch security is essential and implementing Device-ID-based policies play a key role in strengthening our defenses. By integrating these policies with App-ID and User-ID, we create a comprehensive security framework that effectively protects against threats. Earlier, with the PA/SASE license, Prisma SD-WAN customers could get enhanced visibility into OT, IoT, and endpoint devices at their branches. Now, these device IDs can be seamlessly incorporated into security policies, enabling enforcement based on specific device IDs. This advancement delivers unparalleled security and granular control over path selection.

Features Introduced in Prisma SD-WAN Release 6.5.1

Secure Group Tag (SGT) Propagation

Secure Group Tag (SGT) enables identity-based security and enforces policies across networks. It preserves SGT information end-to-end, controlling access over public and private VPN overlays. You can customize SGT propagation per site, including Branch, Data Center, and Branch Gateway locations. When enabled at the site level, SGT allows the ION device to parse Cisco Metadata headers, extract Security Group Information (SGI) values, and preserve them across the Prisma SD-WAN. The system parses Cisco Metadata headers to extract and apply SGT values across the network. It also introduces LAN to LAN propagation and static SGT configuration for ION initiated traffic.

You can configure Static Tag values for ION-initiated traffic (e.g., NTP, DHCP, App Probes) and enable or disable SGT settings at the interface level. Static SGT tagging ensures effective routing and consistent propagation across the network, regardless of topology.

SGT information can be accessed through the Flow Browser and Device Toolkit commands, allowing for enhanced troubleshooting and monitoring capabilities.

Support for GCM Encryption

The Galois/Counter Mode (GCM) support in Prisma SD-WAN enhances your network security by offering advanced encryption for both fabric tunnels and standard VPN connections. This feature introduces AES-GCM-128 and AES-GCM-256 algorithms, providing Authenticated Encryption with Associated Data (AEAD) capabilities. By implementing GCM, you gain improved performance and stronger security compared to traditional CBC modes.

You can now configure GCM encryption for specific tunnels, ensuring compatibility with both static and dynamic IPsec setups. This feature is particularly beneficial when connecting to third-party services or when you require heightened security measures for sensitive data transmission. The implementation supports IKEv2 authentication protocols and integrates seamlessly with existing key management processes.

Port Channel Interface

The LAG (Link Aggregation Group) and LACP (Link Aggregation Control Protocol), commonly called port-channel, on Layer 3 ports on the LAN side. LAG and LACP support enhances your network infrastructure by allowing you to combine multiple physical interfaces into a single logical interface.

LAG and LACP support aligns with industry standards, allowing seamless integration with your existing network equipment. By leveraging this capability, you can enhance your network performance, simplify management, and improve overall user experience across your distributed enterprise environments. Link Aggregation Groups enable combining one or two network connections in scenarios where higher throughput or fail-over capabilities are essential.

LACP, on the other hand, is a protocol that manages the bundling of these physical links, ensuring proper load balancing and link status monitoring. This includes details on creating and modifying LACP on supported interfaces.

Support for Easy Onboarding of Panorama Managed Prisma Access

Effortlessly integrate Prisma SD-WAN with Prisma Access through a native onboarding process. Prisma SD-WAN supports this integration for both Cloud Managed and Panorama Managed Prisma Access.

Earlier, you needed the Prisma Access for Networks (Cloud Managed) CloudBlade and Prisma Access for Networks (Panorama Managed) CloudBlade to connect Prisma Access to Prisma SD-WAN. With the native SASE Integration with Prisma SD-WAN feature, you can directly onboard Prisma SD-WAN sites to Prisma Access, bypassing the need of a CloudBlade.

In case you have previously set up a CloudBlade to establish the connection between Prisma SD-WAN and Prisma Access, you must first deactivate the CloudBlade and contact Palo Alto Networks Customer Support before using this workflow.

Cellular Carrier Certification Enhancements

New modem firmware is introduced for ION 1200-C5G-WW and ION 1200-S-C5G-WW. If an ION device is running on old firmware, a notification is displayed on the Strata Cloud Manager web interface informing the user to upgrade the software. The firmware applies to ION software version 5.6.1 and higher, however, Palo Alto Networks recommends moving to software version 6.1.6 or above before upgrading to recommended modem firmware.

Device TACACS+

Prisma SD-WAN supports TACACS+ (Terminal Access Controller Access Control System+)

authentication protocol that controls network device access, and SSH login for controller nodes in a network infrastructure. TACACS+ uses a TACACS+ server profile to record user behavior, such as when a user started using a specific service, the duration, and when they stopped using it. This helps to create logs and records of the initiation and termination of services and any services in progress during the user’s session, which you can use for auditing purposes.

A device TACACS+ profile consists of multiple configured TACACS+ servers. You can add a maximum of four servers, depending on servers reachability, the system tries to sequentially connect to the available servers in the profile. If a user is present in the TACACS+ server and enters the correct credentials, the user logs in successfully.

Enhanced DC Routing Capabilities

Enhanced DC routing capabilities address critical challenges and adapt to your network's evolving needs, ensuring it remains efficient and effective.

Optimized Data Center (DC) Prefix Advertising: DC Site or ION devices now support advertising specific DC prefixes or learned prefixes to the overlay Fabric. Your branch locations can now prioritize traffic through their preferred data center, ensuring faster and more reliable connections tailored to your organizational needs.
Enhanced Prefix Management: DC ION devices can now advertise summary prefixes to the Core network, effectively addressing scale limitations. Our solution simplifies and scales your network's ability to handle large numbers of prefixes effortlessly.
Automated Asymmetry Correction: Network asymmetry can pose a risk in scenarios where branch traffic routes through Prisma Access or other cloud security platforms. Our new functionality automatically detects and corrects asymmetry, ensuring smoother, more balanced traffic flows and compliance with security protocols.
Intelligent Traffic Rerouting: DC ION devices can detect core network connectivity failures. When such issues arise, traffic is seamlessly redirected to alternative overlay paths within the same data center, maintaining uninterrupted service and enhancing network resilience.

Performance Policy Enhancements

The Move Flows action in performance policy rules now offers greater flexibility for managing traffic, maintaining performance, and enforcing SLA requirements. With the addition of the App/Network SLA Rule Type, you can use Move Flows to better control traffic.

Previously, the action only excluded SLA-violating paths for new flows, leaving existing flows unchanged and relying on Link Quality and Application Metrics unless the field was empty. Now, you can choose between Move Flows Graceful and Move Flows Forced for more control:

Move Flows Graceful moves existing flows and excludes paths for new flows that violate SLAs, considering Link Quality and Probe Metrics.
Move Flows Forced actively shifts flows from non-performing paths to better ones, even across NAT boundaries, using Link Quality and Application/Probe Metrics.

Move Flows Forced triggers on events such as WAN interface changes, link degradation, app unreachability, probe failures, or path revalidation. It supports various path types, including private/public VPNs, Direct Internet, and enterprise VPNs, across active and backup configurations.

Flow Visualization Enhancements

Flows give insights into various network flows, such as branch-to-branch, branch-to-data center, and branch-to-third-party VPN connections. This view helps identify network issues, understand traffic routing, and assess how network policies impact specific flows.

Flow details improve visibility into network traffic by offering end-to-end session details. They allow you to visualize a flow’s path across multiple sites and network segments, enhancing troubleshooting, traffic analysis, and network optimization.
