Flow Vision flows
44
Number of supported flows
On chassis-based platforms, Flow Vision supports a maximum of 512 user-defined flows. On
fixed-port platforms, Flow Vision supports a maximum of 128 user-defined flows. However, there is
a combined limit from all features of 64 flows (including static flows, root flows, and sub-flows,
whether active or inactive) for any one port. In addition, there are individual limits for each Flow
Vision feature;
Table 153 lists these limits. When you create a flow, Flow Vision verifies that there is
no identical active flow.
Refer to the individual features for feature-specific restrictions.
Learned flows
Flow Vision creates a learned flow by using an asterisk (*) for the source device, the destination
device, or both devices. This allows Flow Vision to learn all of the source and destination device
pairs passing through the switch using a specified ingress or egress port without having to identify
all the devices.
• Flow Vision uses an asterisk (*) to indicate a learned flow.
• Learned source device or destination device values are only supported on 16 Gbps-capable FC
ports.
• Only supports one learning flow per ASIC.
• Each Flow Vision feature uses learned flows as follows:
- Flow Monitor can learn all the source device and destination device pairs passing through
the ingress or egress port defined in a flow. Does not support a learned flow for Flow
Monitor flows defined using the LUN, Frame Type, or Bidirectional parameters. Only
supports a learned flow on E_Ports and F_Ports.
- Flow Generator can generate traffic to or from every source or destination device that
shares the zone with the ingress or egress port defined in a flow. When you configure a
learned Generator flow, it queries the Name Server database to identify source and
destination devices that are zoned together. These pairings are not automatically changed
if either member of the pair changes zones. If either member of the pair changes zones,
