Field Notice 0083

July 9, 2022

Release 17.0.0 will introduce a change to the WIPS feature for on-premises deployments

Field Notice 0082

June 27, 2024

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.

Field Notice 0081

June 19, 2024

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.

Field Notice 0080

March 19, 2024

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.

Field Notice 0079

January 9, 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.

Field Notice 0078

Date: December 14, 2023

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.

Field Notice 0077

December 12th, 2023

The prior versions of CV-CUE (called Aware) supported model specific templates that allowed different configurations for different AP models. With release 17.0.0, the system will stop supporting model specific templates altogether. This requires customers to perform the following actions.

Field Notice 0076

December 12th, 2023

Release 16.0.0 will introduce two changes to the WIPS feature.

Field Notice 0075

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.

Field Notice 0074

January 15th, 2024

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.
