So let's talk about what new features has been added on the Cisco Catalyst SD-WAN release 20.15.x

  • Converged Cisco SD-WAN Manager and Cisco SD-WAN Analytics Dashboard introduces a converged dashboard in Cisco SD-WAN Manager that merges the monitoring and analytics capabilities from both Cisco SD-WAN Manager and Cisco SD-WAN Analytics. This converged dashboard displays management data from the Cisco SD-WAN Manager alongside analytical insights from Cisco SD-WAN Analytics, all within a single interface.
  • Generate an Admin-Tech File with Custom Commands feature enhances the output of the admin-tech file with additional command output information. With this feature, You can generate a customized admin-tech file with the required show command output details to help in troubleshooting. Custom admin-tech is independent of tech, core, and logs flag.
  • Share Traffic Information with Cisco Security Service Edge shares VPN and security group tag (SGT) information with Cisco Security Service Edge (SSE). This is called context information. SSE applies different policies to traffic based on the context information of the traffic.
  • Configure EtherChannels using Configuration Groups by which you can configure EtherChannels on service and transport side using configuration groups.
  • Load Balancing for EtherChannels on Individual Port Channels by which you can load balance EtherChannels for individual port channels on service and transport side using CLI templates.
  • BFD Troubleshooting for Cisco Catalyst SD-WAN Using Radioactive Tracing provides the ability to troubleshoot BFD protocols using radioactive (RA) tracing. RA tracing enables debug logs across various processes which participates and handles a particular BFD session.
  • Multicast Support for Hub and Spoke Topologies enables efficient distribution of one-to-many traffic for hub and spoke devices. The multicast routing protocols like, IPv4 Multicast, IGMPv3, PIM SSM, PIM ASM, Auto RP and Static RP distribute data to multiple recipients.
  • Packet Duplication using Underlay Fragmentation feature uses adjacency MTU to combine with underlay fragmentation which allows the successful transmission of packets that exceed the MTU limitations by breaking them down into manageable fragments and ensuring their reliable delivery.
  • Cisco Catalyst SD-WAN Firewall High Availability you can set up two Cisco IOS XE Catalyst SD-WAN devices in either active-active or active-standby configurations. When HA is enabled, features like the Zone Based Firewall (ZBF) and Network Address Translation (NAT) utilize this functionality to synchronize their states between the devices, whether in active-standby or active-active modes. In the event of a failure of the active device, the standby device seamlessly takes over operations without interrupting session flows, thus eliminating the need for reconnection.
  • Cloud OnRamp for SaaS Workflow Cisco SD-WAN Manager allows you to select specific SaaS applications and identify best performing paths for each of these SaaS applications using a fully-guided workflow.
