Commands for Status Monitoring and Statistics
configure flowstats export add port
configure flowstats export <group#> add [<ipaddress> | <hostname>]
<udp_port>
Description
Adds a flow-collector device to an export group to which NetFlow datagrams are exported.
NOTE
This command is available only on the “i” series switches.
Syntax Description
Default
N/A
Usage Guidelines
You can configure up to 32 export distribution groups. Each group may contain up to eight
flow-collection devices. At least one flow-collector destination must be configured for NetFlow
datagrams to be exported to a group.
When multiple flow-collectors are configured as members of the same group, the exported NetFlow
datagrams are distributed across the available destinations. This NetFlow-distribution feature enables a
scalable collection architecture that is able to accommodate high volumes of exported data. The
distribution algorithm ensures that all the records for a given flow are exported to the same collector.
The algorithm also ensures that flow records for both the ingress and egress directions of a TCP or UDP
connection are exported to the same collector (when both flows traverse the same link and both filters
are configured to export to the same group).
Issuing this command also enables the collection of NetFlow statistics.
For the BlackDiamond Switches. See Chapter 22 for information about a similar command for the
PoS module.
Example
The following command adds the flow-collector device with IP address 10.205.30.15 using UDP port
2025 to export group 5 for this switch:
configure flowstats export 5 add 10.205.30.15 2025
group# Specifies the export group to which the specified flow-collector device should be added. The
group number is an integer in the range of 1-32.
ipaddress Specifies the IP address of a flow-collector destination.
hostname Specifies the host name of a flow-collector destination.
udp_port Specifies a UDP port for the destination flow-collector.
