Brocade Flow Vision Administrators Guide (Supporting Fabric OS v7.3.0) - Manual (Page 58)

• The calculated Rx and Tx frame size values displayed in the output are accurate within a range of
-4 through +8 bytes. For example, a frame size value of 256 bytes may actually be anywhere from
252 to 260 bytes in size.
• For Flow Monitor flows passing through the base switch in a VF-enabled fabric the source fabric ID
(SFID) and destination fabric ID (DFID) values must be specified when the flow is defined.
The following limitations apply to 16 Gbps-capable Fibre Channel platforms, including the Brocade
FC8-32E and FC8-48E blades:
• They support a maximum of 2 flows defined using a combination of ingress port and frame type
parameters per ASIC chip.
• Each port supports a maximum of 12 flows defined using both egress port and frame type
parameters.
• Flow Monitor can only monitor flows that are using EX_Ports.
The following limitations apply to 8 Gbps-capable Fibre Channel platforms and blades:
• They do not support monitoring flows using both ingress port and frame type parameters.
• Each port supports a maximum of 12 flows defined using both egress port and frame type
parameters, except for the Brocade 300, 5300, 5410, 5424, 5450, 5460, 5470, 5480, 7800 and
7840 platforms, which support a maximum of 8 flows per port.
• They cannot show statistics for SIM ports.
• They do not support learning.
