Hash key data

Hash key type 18 is an inner 2-tuple where the hash key data is the contents of these packet header fields:

  • Inner 32-bit IPv4 / 128-bit IPv6 source address
  • Inner 32-bit IPv4 / 128-bit IPv6 destination address

The hash key data for hash key type 18 is the same as for hash key type 4 (see Hash Key Type 4: 2-Tuple) except that the IPv4/IPv6 datagram resides in a tunnel (refer to Tunnel Type Classification for supported tunnel types).


Hash key type 18 is valid for frames containing an inner IPv4 packet or an inner IPv6 packet.
