Conditional parameter. See details in Parameters below.

Function Description

Next Generation API replaces tfGetArpEntryByPhysAddr().

Parameters

• interfaceHandle

  Interface ID as returned by tfAddInterface(). NOTE: This parameter is conditional and only present when TM_USE_STRONG_ESL is defined at compile time. For more information, please see Appendix C: Strong End System Model / Weak End System Model.

• addrFamily

  Set to AF_INET if you want to get an entry from the IPv4 ARP cache, AF_INET6 if you want to get an entry from the IPv6 Neighbor cache.

• physAddrPtr

  The physical address to lookup the entry in the ARP cache.

• physAddrLen

  The length of the physical address.

• arpIpAddrPtr

  The location where the IP address of the matching physical entry will be stored.

Returns

• TM_ENOERROR

  Success

• TM_EINVAL

  One of the parameters is invalid.

• TM_EAFNOSUPPORT

  addrFamily was not set to either AF_INET or AF_INET6.

• TM_ENOENT

  No such ARP entry exists.
