ArpHeader data structure
API function ARP_USER_CB - Install ARP callback function
typedef struct tagAtEntry {
long IfIndex; // Interface on which this entry maps
unsigned char PhysAddress[11]; // Physical address of destination
unsigned char PhysAddressLen; // Length of PhysAddress
unsigned long NetAddress; // IP address of physical address
} atEntry;
These structures are only available in @CHIP-RTOS versions which contain the SNMP option. A SNMP agent is not part of
the @CHIP-RTOS. But if a user is able to implement an agent based on the TCP/IP API, they need access to the internal
TCP/IP SNMP variables.
