Feature Description

Hash key data

Hash key type 21 is an inner 5-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
  • Inner 16-bit UDP, TCP or SCTP source port number
  • Inner 16-bit UDP, TCP or SCTP destination port number
  • Inner 8-bit IPv4/IPv6 protocol number / next header

The hash key data for hash key type 21 is the same as for hash key type 9 (see Hash Key Type 9: 5-Tuple Sorted) except that the IPv4/IPv6 datagram resides in a tunnel (refer to Tunnel Type Classification for supported tunnel types).

Validity

Hash key type 21 is valid for frames containing an inner IPv4 packet or an inner IPv6 packet with a UDP, a TCP or an SCTP packet as payload.
