Forum Post: Not able to get the MAC address

Hi, I am using the following api to get the interface information. ULONG lsw = 0; ULONG msw = 0; ULONG ipd = 0; ip_0 is properly going. nx_ip_interface_info_get(&ip_0,1,(CHAR *) "NetX IP Instance 0",&ipd, 0xFFFFFE00UL,0xC,&msw,&lsw); But all values are returning 0; i Want to get the MAC address of the IP instance. Anything i am missing here? Regards, Nandan G
