Brocade Communications Systems A7533A - Brocade 4Gb SAN Switch Base Command Reference Manual page 547

The port mirroring feature is only supported on the following platforms: Brocade 4100, Brocade
4900, Brocade 7500, and Brocade 48000 Option 5.
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 command outputs the total number of transmit and receive bytes for each port.
In the 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.
Operands This command has the following operands:
slotnumber
portnumber
SourceID
DestID
Examples To configure a port as a mirror port:
To add a port mirror connection between two local switch ports:
To add a port mirror connection between a local switch port and a remote switch port:
To delete a port mirror connection between two local switch ports:
To delete a port mirror connection between a local switch port and a remote switch port:

For bladed systems only, specify the slot number of the port on which the
mirror port is located, followed by a slash (/).
Specifies the number of the port on which the mirror port is located, relative
to its slot for bladed systems. Use switchShow for a list of valid ports. This
port 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.
