Before sending ping (ICMP) packets, the station needs to map IP addresses to MAC addresses, so it sends ARP. ![]() but i dont know how to find the device ip and Mac id in the capture. The script basically pings all hosts on the network. eth.addr Address Ethernet or other MAC address 1.0.0 to 4.0.0 Address OUI Unsigned integer (3 bytes) 3.2.0 to 4.0.0 Address OUI (resolved) Character string 3.2.0 to 4.0.0 eth.addrresolved Address (resolved) Character string 1.12.0 to 4.0.0 eth.dst Destination. i have taken packet capture by connecting one end of lan cable with my windows laptop and another end with my access point Ethernet port to get the detail of the device. ![]() Trace.We have not connected the external Ethernet switch.Both the laptops are standalone. Write down the IP and MAC addresses associated with the selected Ethernet adapter.That is the source address to look for when examining captured packets. i need to find the device mac id and ip address of the access point. I am not able to see the DHCP offer & DHCP acknowledge message from the wire shark S.Saravanakumar: As per the attached wire shark trace, I could able to see the DHCP discover packet with Unicast type.

Network addressing works at a couple of different layers of the OSI model. As the name suggests, it is designed to resolve IP addresses into a form usable by other systems within a subnet. Thank you for the feedback.Here with I have attached the wireshark trace.įrom the Launchpad XL2 RJ45 port, CAT5 ethernet cable is connected.
