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.

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.

This field notice is regarding restriction of EOS software image architecture support on certain SKUs with 4GB and 8GB of RAM. Arista EOS is developed on a single codebase and has supported both 32-bit and 64-bit code architectures, with no difference in feature and function support. Starting with EOS release 4.32.0F, targeted to be released between March and April 2024, to optimize platform capabilities, systems listed below will only support either 32-bit or 64-bit EOS images.

Release 16.0.0 will introduce two changes to the WIPS feature.

Arista and Dell have jointly decided to terminate their partnership on DMF (DANZ Monitoring Fabric), CCF (Converged Cloud Fabric) and MCD (Multi-Cloud Director) products.

From January 27th, 2024, customers running a combination of affected versions of CloudVision Portal, and the hardware platforms listed below, may experience issues with the Zero Touch Provisioning (ZTP) of devices into CloudVision.

It has been identified that with a wide variety of physical tolerances there are occasions where an optic or cable is difficult to remove from a switch. A new optic extraction tool is now available to assist with QSFP, QSFP-DD and OSFP removal and prevent damage to the switch port in cases where an optic is difficult to extract.

In very rare circumstances some models of the DCS-7280SR3-48YC8 and DCS-7280SR3K-48YC8 may exhibit buffer memory related errors. This is caused by a misprogramming of the power profile in the voltage regulator. The incorrect power profile may result in HBM CRC errors and packet drops. The problem is corrected by a new version of the voltage regulator programming delivered through an EOS SWIX.
