Fabric Engine Release Notes

General Enhancements

This release introduces the following enhancements:

Fail Open I-SID enhancement—You can now configure the Fail Open I-SID as the same I-SID value assigned by RADIUS VSA.
LLDP-MED enhancement—You can now configure LLDP-MED network policies on ports using EDM. In previous releases, you could only view this information in EDM.
RADIUS Dynamic Server—You can now configure up to eight clients.

This release adds the following Multi-Area enhancements for 7520 Series and 7720 Series:

Increase the number of nodes that can function as boundary nodes from two to four.

Note

5520 Series and 5720 Series continue to support a maximum of two nodes that can function as boundary nodes.
Ability to configure virtual NNI links for Multi-Area boundary nodes—Boundary nodes in the Multi-area SPB network require a robust Fabric path between them in both areas (home and remote). If a robust connection for one of the areas is not possible, you can create a virtual NNI link and establish a virtual Fabric adjacency over the area with the robust connection.

The software supports the following enhancements for ExtremeCloud SD-WAN:

5320 Series support— On models that support a single active VRF, you can now specify the VRF name that Auto-sense uses for the SD-WAN configuration.
Auto-sense port Multi-area SPB support—On boundary nodes, you can configure in which IS-IS area Auto-sense creates an ExtremeCloud SD-WAN-learned interface.
ExtremeCloud SD-WAN Bypass and MPLS support—Auto-sense automatically configures Link Debounce on the switch port that connects to SD-WAN Appliance. This configuration enables the switch that connects to the appliance LAN1 port to keep using its FE VXLAN tunnels over MPLS transport, even if SD-WAN Appliance is down, Layer 3 WAN Internet ports are lost, and the appliance is in Bypass mode.

In an earlier release, ZTP+ configuration supported assigning a CLIP in the GRT. Now the CLIP can be used for switch management.
