NimbostratusHow to know which virtual server is handling a particular traffic
Hello,
I would like to know a command to know for sure which virtual server is handling a particular traffic.
I'm using 5200 as firewall and I have lots of L3 forwarding virtual servers.
So I was hoping for an equivalent of Cisco's: show ip route 10.0.0.1.
From this I can know for sure what's the route or connected interface that handles said traffic.
Some thing like: tmsh show ltm virtual-address 10.0.0.1
But NOT like: tmsh show ltm virtual-address | grep 10.0.0.1
Cheers!

I am not sure about command. But please run the TCPDUMP based and find.
bojan_sukalo_20Tcpdump is only valid if there is an actual traffic going through a virtual server.

Hi Mate,
As Samir mentioned, run TCPDUMP and see where the traffis is going.
You can run the below command for tcpdump.
tcpdump -s0 -nni 0.0:nnn host <IP address> -w /var/tmp/trouble.pcapYou can download the file from /var/tmp/ and open it with wireshark.
Hope this helps.

Hello,
This helps ONLY if there is a traffic on the virtual server. I use this and understand this very well. The question here is if there's a way to know for sure which particular VS is handling traffic from config only and not from traffic.
Thank you all nevertheless.

Hi,
You can do it manually, see here:
https://support.f5.com/kb/en-us/solutions/public/14000/800/sol14800.html
(Along with the supplemental inforamtion links which may be useful for your case)
It would be nice if there was an automated way for that. You can open a feature request with the support, they may ask you some questions and escalate your request to the dev teams.
