Interface utilization is going 98% (recieved) in the VSX gateway

Hi All,

In of our Checkpoint box inetrface utilization is going 98%(recieved) so just want to know which which users are sending the most 

traffic and try to catch them . Gateway is R77.30 and want to know the output just like "ip-accounting" in Cisco ...

Please require your support .

Hi All 

 

One thing also want to add that eth1-06 is the physical interface of the VSX gateway which is showing 96% of recieved utilization 

and no ip is configured on this . There are 7-8 VSs like checked vsenv 7--> eth1-06.2781 like this different VLANs interfaces belong

to different VSs.

Very basic, but have you tried tcpdump, often enough you can see high bandwidth users from tcpdump. Just explicitly set good flags to stop the capture and not to saturate CPU. I.e count, -c xxx

Hi Kaspers ,
Thanks for confirmation
What will be tcpdump command to identify high bandwidth users ?

You can always look with cpview to see if you can find the top network users.
The tcpdump command would be something like:
tcpdump -i eth1-06 -c 1000
to capture a max of 1000 packets.
Make sure the scrollback buffer from your SSH program is set big enough to scroll back through those lines.

Hi Kaspers ,
But how we can identify which host or servers is taking most bandwidth or most packets like "ip accounting " in cisco ?

See the VSX-specific sections of these SK's, the short answer is you have to use CPMonitor:

If its alot of sessions its possible to check the top sources/top destinations within the smartlog. it have helped me from time to time. dosn´t really say high bandwidth just number of sessions.

Hi Magnus ,
If we want to find the top source and destinations in interface wise . Can we do it through smartLog ?

well you do have the routing table/antispoofing so just filter on those prefixes(networks) first then smartlog will do new calculation on top source and destinations.

How about using SmartviewMonitor and looking for top source, destination or service on the interface ?
