Introduction
This document describes the pre-configuration required in order to enable Flexible Netflow Functionality on the ASR903 router.
Note: Click here to understand more on working of Flexible Netflow.
Prerequisites
Requirements
Cisco recommends that you have knowledge of the Flexible Netflow feature configuration.
Components Used
This document is not restricted to specific software and hardware versions.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
Background Information
Flexible Netflow on ASR903 platform is supported starting from XE3.18.0 SP release. However, you get this error when you try to configure the feature:
Router_ASR903(config)#int BDI10
Router_ASR903(config-if)#ip flow monitor TEST_IPV4_MONITOR input
% Flow Monitor: Failed to add monitor to interface: Unsupported template
Router_ASR903(config-if)#int GigabitEthernet0/1/0
Router_ASR903(config-if)#ip flow monitor TEST_IPV4_MONITOR input
% Flow Monitor: Failed to add monitor to interface: Unsupported template
Router_ASR903#
Configure
You need to enable the metroaggrservices license on the ASR903 router. This is the configuration:
Router_ASR903#config t
Enter configuration commands, one per line. End with CNTL/Z.
Router_ASR903(config)#license boot level metroaggrservices
Router_ASR903(config)#end
Router_ASR903#write
Building configuration...
[OK]
Router_ASR903#
A reload of the device is needed for the new license level to take effect. Once the device is reload, the license level can be verified from the output of show version.
