Context config>cflowd
Description This command specifies the maximum number of active flows to maintain in the flow cache table.
The no form of this command resets the number of active entries back to the default value.
Parameters num-entries — The maximum number of entries maintained in the cflowd cache. It depends on the
CPM version.
Values
Default

Syntax collector ip-address[:port] {version [5 | 8 | 9 | 10]}
no collector
Context config>cflowd
Description This command defines a flow data collector for cflowd data. The IP address of the flow collector must
be specified. The UDP port number is an optional parameter. If it is not set, the default of 2055 is used
for all collector versions. To connect to a IPFIX (version 10) collector using the IPFIX default port,
specify port 4739 when configuring the collector. The version must be specified. A maximum of 5
collectors can be configured.
The no form of this command removes the flow collector definition from the config and stops the
export of data to the collector. The collector needs to be shutdown to be deleted.
Default none
Parameters ip-address — Specifies the address of a remote Cflowd collector host to receive the exported
Cflowd data.
