Typically, a reboot should clear it. If it's still happening after&nbsp; reboot, then it will need to be replaced. Also, ensure that your firmware is on 4.1.3d which is the last supported NOS version for the 6720 platform.&nbsp;<BR /><BR />Regarding the packet loss, it's possible the buffers are getting overun resulting in RX discards (tail drops) since it's the only path for all traffic.&nbsp;</SPAN> Thu, 24 Mar 2022 08:33:33 GMT https://community.extremenetworks.com/t5/data-center-vdx/vdx6720-60-hw-asic-chip-fault/m-p/69244#M350 Truyen_Phan 2022-03-24T08:33:33Z
