I'm having trouble setting IP ACLs on a SPAN for source FEX ports on a Nexus 5500 Series. I do get the traffic just fine when the ACL is not in place, but once I set the ACL for the monitoring session, that traffic is not longer mirrored. Is this a limitation of FEX?
I read that it is a limitation on the 9000 Series, for example, in the context of ERSPAN:
ACL filters are not supported for FEX ports
But does this apply to older series as well?
