IP flow ingree vs egress

[Suresh Babu]

Hi All,

Need the clarity on IP flow ingress and egress and their functionality

And please correct my understanding on both

ingress - Which monitors traffic enters into interface from LAN

Egress - Which monitors traffic enters into interface from WAN

And also confirm the difference if i configure ingress on LAN interface and egress on WAN interface.

Thanks in advance

Regards

Hi Suresh

Ip flow ingress will monitor  the traffic entrering to the interface where  you have configured it

Ip flow egress will monitor the traffic exiting out of the interface where you have configured it

Hi Suresh,

There is nothing specifc on LAN or WAN. It monitores the ingress or egress traffic  based on the config you have applied on the interface

Thanks

Hi Raj,

If you consider the traffic from LAN and WAN, i feel there is a different

LAN interface - entering from WAN traffic is download and entering from LAN is upload traffic

WAN interface - it will reverse to above explanation

in addition to above

If i configure the ingress command on LAN interface and egress command on WAN interface will it monitor the up and download traffic or only one way traffic. Please confirm

Please clarify me on above considerations.

Hi Suresh,

This will monitor the traffic coming to LAN interface and traffic going out of WAN interface

If your traffic is coming via LAN and goes out of WAN, then  this will be showing  traffic only in one direction that is traffic flowing out

Thanks
