Hello,

When I try to configure the DirectFlow action to set the destination MAC, the switch tells me that it is not supported. According to the EOS manual, Trident || platform should support action set destination mac. Is this an issue with the HW or SW version?

Arista DCS-7050TX-48-R
Hardware version: 01.10
Software image version: 4.14.9M
Architecture: i386
Internal build version: 4.14.9M-2574618.4149M
Internal build ID: 76f850a0-b7c0-4cf8-b793-494293d7029f

Based on the platform config command, it is a Trident 2 platform.

Thanks…

Roger

Hi Roger,

For the DCS-7050TX (T2) platform rewrite of the MAC address was first supported in EOS 4.15.0F.
