inspect skinny

inspect icmp

class class-default

flow-export event-type all destination 10.110.151.11

Can you tell me pls how could how could i enable bidirectional support.

Also if netflow in ASA ver 8.4(6) is unidirectional then would it not work.

Hello Anukalp.

Exactly, on that version you could only use unidirectional,

How to enable it? I am not 100% sure but I think is the only method it supports so it will be on by default,

There is no command for it on the command reference so it's just the mode you have on this version

Hi jcarvaja,

I have nothing to do with unidirectional or bidirectional. My issue is that NetFlow collector is showing traffic of ASA. It was working fine on version 8.2(5). After upgradation it to 8.4(6) my netflow collector stops displaying data. I have mentioned config above of netflow in ASA of both version 8.2(5) & 8.4(6).

I just need to know if there is any changes in 8.4(6) which need to configure so that my netflow collector start displaying traffic.

Consider downloading the Cisco ASA Guide to NetFlow Security Event Logging and Cyber Threat Detection. It should help.
