Monitor session can only capture one direction traffic

[deepeshs]

my config

On the dst port i can only see one direction (tx) traffic to the source port. Why would that be?

Hi,

not able to understand exact query, but what i understand you are monitoring rx/tx traffic of port Eth103/1/13 and copy of that traffic sending on port Eth1/19 over which you must have connected a laptop with wireshark installed.

In such case on port Eth1/19, we will se Tx traffic only. Please correct me if i did not understand your query properly.

Yes that is correct Akash.

My expectation was as I am capturing tx and rx on port  Eth103/1/13. 

I should see on port 1/19 which is monitor port.

If that wouldn't not be the case what should I do to capture both tx and rx packets.
