Abstract
Aspects include includes receiving, at an input/output (I/O) processor, a transport control word (TCW) that includes an instruction to perform virtual port mirroring. The I/O processor identifies a first port to be mirrored and a virtual port to perform the mirroring. The virtual port is a first memory location in a memory. In response to outbound data being sent to the first port for transmission to a first target device and to the instruction specifying outbound port mirroring, the I/O processor stores a copy of the outbound data in the first memory location. In response to inbound data being received at the first port and to the instruction specifying inbound port mirroring, a copy of the inbound data is stored at the first memory location.
