portMirror
The mirror port location can impact the latency of mirrored frames.
Setting up multiple mirror connections on a core-edge platform between devices will mirror additional
traffic. If user has two mirror connections, device A to device B and device C to device D. The mirror
port will see traffic between A to B and C to D. In addition, the mirror port will see traffic between A to
D and C to B.
The portPerfShow
case of a mirror port, the portperfshow will show double the amount of traffic because the mirror port
transmits the frame and also receives the frame.

The execution of this command is subject to Admin Domain restrictions that may be in place.

port is located, followed by a slash (/).
Specifies the number of the port on which the mirror port is located, relative to its

number will be the mirror port in which the mirror traffic is shown.
Specifies the 3-byte SID (source ID) of the originator device, in "0xDDAAPP"
format, where DD is Domain ID, AA is Area ID and PP is AL_PA ID. For
example, 0x050200 has a domain ID of 5, an area ID of 2, and AL_PA ID of 0.
SourceID and DestID cannot both be 0x000000.
Specifies the 3-byte DID (destination ID) of the destination device, in
"0xDDAAPP" format, where DD is Domain ID, AA is Area ID and PP is AL_PA
ID. For example, 0x050200 has a domain ID of 5, an area ID of 2 and an AL_PA
ID of 0. SourceID and DestID cannot both be 0x000000.
