Configuring Sampled NetFlow Globally
To configure sampled NetFlow globally, perform this task:
When you configure sampled NetFlow globally, note the following:
• The valid values for rate are 64, 128, 256, 512, 1024, 2048, 4096, and 8192.
• The valid values for the packet-based export interval are from 4000 through 16,000.
See the “Sampled NetFlow” section on page 33-6 for more information.
Configuring Sampled NetFlow on a Layer 3 Interface
Note • With the full-interface or destination-source-interface flow masks, you can enable or disable
sampled NetFlow on individual Layer 3 interfaces. With all other flow masks, sampled NetFlow is
enabled or disabled globally.
• The Layer 3 interface must be configured with an IP address.
To configure sampled NetFlow on a Layer 3 interface, perform this task:
This example shows how to enable sampled NetFlow on Fast Ethernet port 5/12:
Router# configure terminal
Router(config)# interface fastethernet 5/12
Router(config-if)# mls netflow sampling
Router(config)# end
Router#
Command Purpose
Step 1
Router(config)# mls sampling {time-based rate |
packet-based rate [interval]}
Enables sampled NetFlow and configures the rate. For
packet-based sampling, optionally configures the export
interval.
Router(config)# no mls sampling
Clears the sampled NetFlow configuration.
Step 2
Router(config)# end
Exits configuration mode.
Command Purpose
Step 1
Router(config)# interface {vlan vlan_ID |
type
1
slot/port}
1. type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet
Selects an interface to configure.
Step 2
Router(config-if)# mls netflow sampling
Enables sampled NetFlow on the interface.
Disables sampled NetFlow on the interface.
Router(config-if)# no mls netflow sampling
Step 3
Router(config)# end
Exits configuration mode.
