Flow Vision Administrator’s Guide 3

Flows

When creating or viewing a flow, you can specify any combination of the three features in the flow

command. For example:

flow --create flowname -feature monitor,generator <parameters>

flow --show flowname -feature mirror,generator <parameters>

Flow definition rules

The rules listed in Table 1 identify what parameters can be used to define a flow.

Supported port configurations

Table 2 lists the supported configurations for each Flow Vision feature using only the basic flow

identification parameters (ingrport and srcdev, egrport and dstdev).

If you are using at least one advanced parameter (lun, -frametype, or -bidir), then feature-specific

rules apply. Refer to the individual Flow Vision features for specific details.

NOTE

Neither ranges nor lists are supported for any parameter.
