Use this utility to ping the i series and it should return the mac address also unless your switches block mac arp packets

or you can do this

Locating the MAC address of a networked computer from Windows:

Click Start -> Run, type cmd and click Ok
Type ping xxx.xxx.xxx.xxx, replacing xxx.xxx.xxx.xxx with the IP address of the computer who's MAC address you want to retrieve

After the ping response has finished, type arp -a

Under Internet Address, locate the IP address you just pinged. In the same line, the corresponding MAC address is listed under Physical Address
Your iSeries should be using a static IP address outside the range that you assign to DHCP. No system using DHCP should ever be assigned that address.

Of course, if a second system is attached and it uses the same static IP address, the same conflict can happen. It's somewhat irrelevant that DHCP is involved except that the iSeries (probably) shouldn't be using it.

But if you really need the adapter address, you can most likely run DSPLIND ETHLINE. The adapter address is shown as 'Local adapter address'.

Your line description (*LIND) might have been given a name other than ETHLINE. You can use the CFGTCP command and take option 1, 'Work with TCP/IP interfaces'. The interface line for your system IP address will show the name of the associated *LIND under the 'Line Description' column. Use that name with the DSPLIND command.

Note that the hexadecimal value there should correspond with the value seen in the Windows [arp -a] command mentioned by Joshua G.
