Hello,
For some reason, when I am applying ACL to monitor session, it seems that only ingress traffic is captured.
Is this a software or hardware limitation.

Please advise.

Thanks,

Martin

Hi Martin,

Egress filtered mirroring is not supported in EOS-4.21.8M on the DCS-7280SR platform. This support was recently introduced in EOS-4.23.0F.

Pls see the article https://eos.arista.com/eos-4-23-0f/egress-filtered-mirroring/ for specifics on Egress filtered mirroring.

For general Mirroring pls reference https://eos.arista.com/advanced-mirroring-features/

Hi Martin,

Can you provide the MoniACL access list configuration?
