Port mirroring
3
• Deleting a port mirroring connection with IOD enabled causes frame drop between two
endpoints.
• Using the firmware download procedure to downgrade to previous Fabric OS releases that do
not support port mirroring requires that you remove all the port mirroring connections. If you
downgrade to a previous version of Fabric OS, you cannot proceed until the mirroring
connections are removed.
• Port mirroring is supported with Virtual Fabrics with the limitation that you cannot have FCR
enabled within the same 8-port group.
• If you have NPIV or 10-bit address mode enabled on a Brocade 300, 5300, 5410, 5450, 5460,
5470, 5480, 7800, or the M5424 platforms, all devices from the same NPIV port or 10-bit
addressing mode hit the same mirror connection, regardless of different AL_PAs, because the
validation is done only for the first 16 bits of the SID/DID.
• Port mirroring is not supported for the shared area ports of 48-port blades in the default
switch. However, when the ports are assigned to a 10-bit address logical switch, port mirroring
is supported.
• For the 48-port and 64-port blades, port mirroring is always supported on the non-shared area
ports.
For the shared area ports, port mirroring is supported in Virtual Fabrics mode if the ports are
assigned to a 10-bit address logical switch. Port mirroring is not supported on the shared area
ports in non-Virtual Fabrics mode.
If a Fabric Vision license is installed and if port mirror connections are defined or enabled on
16 Gbps-capable Fibre Channel ports, flow creation for Flow Mirror will fail.
Similarly, if a Fabric Vision license is installed and a flow is created or activated for Flow Mirror,
if you attempt to create a port mirror connection using 16Gbps-capable Fibre Channel ports,
the port mirror commands will fail.
Supported platforms
Port mirroring is supported only in FC ports. In general, a platform or blade supporting port
mirroring supports both the mirror ports and the mirror connections. Exceptions are listed in
Table 8.
