CSR1000V netflow configuring...

[megrez80]

I'm trying to configure netflow on a CSR1000V with IOS XE Version 16.05, but am having a problem:

ip-172-31-7-28#enable
ip-172-31-7-28#configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
ip-172-31-7-28(config)#interface GigabitEthernet1
ip-172-31-7-28(config-if)# ip flow egress
                                                        ^
% Invalid input detected at '^' marker.

ip-172-31-7-28(config-if)#

Any help would be appreciated.

Thanks.

I’m wondering if a different iOS or licence is required to allow this feature.

Please try the flexible netflow configuration.

The new command is ip flow monitor "your monitor here" input

ip flow monitor "your monitor here" output

you have to configure record, monitor, and exporter.

You are right, the commands do exist.

The show ip cache flow command is replaced with the show flow monitor "monitor" cache format table command.
