Support for 16 Gbps F_Ports and F_Port trunks is provided on the following devices:
-
Switches: 24-port, 48-port, and 96-port 16 Gbps switches
-
Chassis: 4-slot and 8-slot 16 Gbps Backbone Chassis
-
Blades: FC8-32E, FC8-48E, FC16-32, FC16-48, and FC16-64
•
Disabling a SIM-port that is receiving traffic may produce Class 3 discards for the simulated
traffic; however, this will have no effect on other traffic flows.
Supported flow parameters
Table 91 lists the supported flow configuration parameters for the Flow Vision Generator, Monitor,
and Mirror features.
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 92 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.

Feature-specific flow count restrictions in Flow Vision
Feature Limit to number of flows
