ARP table or route table

How can we get the ARP table or route table of the unit under monitoring by using the SNMP function. Compare with the other monitoring program available on the markets, most the them can show the us the arp , route table as well as the IP address of the device connected to the interface. (i.e. router). Would you please let me know are there any advance setting we have to do in order to get the desired information.

Thanks in advance.
