Hello,

I have a Marvell 98DX3255 in a Mikrotik CCR2116-12G-4S+ and I was very disapointed to see that the mirror just works in one direction.
From what I read, this device which is btw one of the most expensive from Mikrotik should support mirror of both directions.

I have 2 other cheap Mikrotik devices and they work fine.

Does anyone face same issue?

Thank you in advance.

BR,
João

Check 7.15beta release notes:

*) switch - added support for multiple ingress and egress port mirroring on 98DXxxxx switches

So it's coming.
Be advised not to use beta versions if this is a production device where you can not afford downtime.
