# How to access ARP table in wiznet w5300 chip?

## Question

Asked by hammi on 2018-06-29 in Ethernet Chips.

Dear All
I am using wiznet w5300 ethernet controllers to pass treaffic from one network to another networks using switches. I intend to take MAC frames from one IP address and transfer them to another IP address therefore I need to access the ARP table of w5300 embedded ethernet controller to make sure which MAC address of connected devices belongs to which IP address. In simple words I want to access the ARP table of W5300. Is there any way I can access w5300 ARP table?

Thanking you all in advance.

I am not sure, but have suspcion that WIZnet W5x00 devices do not have ARP table in them. If I am correct, you will have to use the chip in MACRAW mode manually implementing ARP table and whole MAC layer up.
