This field notice is regarding Arista platforms belonging to the DCS-7300X3, DCS-7050X3, DCS-7010TX and CCS family, running Arista EOS version 4.31.1F. In deployments with MLAG and VxLAN, MAC move of a remote MAC address to a locally learnt MAC address on the MLAG pair may result in blackholing of the VXLAN encapsulated traffic destined to that MAC address.

A rare race condition in the power cycle behavior of the 7800 Supervisors may cause a supervisor to become unresponsive after reboot. An updated DPM image prevents this issue and can be applied via an EOS SWIX patch. The fix will also be integrated into future EOS maintenance and main releases.

An upgrade to the L3 Leaf Spine Studio in CloudVision includes configuration changes which will modify the MLAG domain name configuration on devices. If these changes are accepted and deployed onto devices in an EVPN deployment, there is a possibility of traffic loss to the connected hosts.

January 9th, 2024

In a VXLAN deployment with switches deployed in MLAG pairs, where the Virtual-ARP functionality is used, an ISSU (In-Service Software Upgrade) from an older version of EOS software to EOS 4.30.2F or EOS 4.30.3M or an ISSU from either of these two releases to a newer EOS software may result in traffic loss until both switches in the MLAG pair are upgraded. Any FX releases based either off 4.30.2 or 4.30.3 are also similarly affected.
