Abstract

Ingress and egress port packets for a connection between a first node and second node are mirrored to a mirroring port on a network switch. A count of ingress and egress port packets associated with a handshake process is determined. Duplicate mirrored packets associated with the connection are filtered based at least in part on the count.
