# MACRAW / Promiciuous mode to sniffer Packets for different Layer 2 device

## Question

Asked by mani9876 on 2018-05-19 in Ethernet Chips.

Hello,

as I can not find very many information about the MACRAW mode, I would like to know if it’s possible to sniffer packets, which have a different destination MAC address, than the MAC address the W5500 itself has. I would like to plug it into a mirrored port, to sniffer some specific packets.

So is this possible?

Thank you
Regards

Hello,

Sorry for the late reply
In conclusion, it is possible.
In macraw mode, w5500 receives packets without mac address filtering.
Thank you
