Required Configuration

...

1090304Available only if an appropriate network interface layer is present (e.g., Ethernet; see section D-7-3 on page 748). Anchor10903051090305 Notes / Warnings Anchor10903061090306IPv4 is enabled, see IPv4 Layer Configuration

Notes / Warnings

NetARP_CacheGetAddrHW() may be used in conjunction with NetARP_ProbeAddrOnNet() to determine if a specific protocol address is available on the local network.
