Description

  • IP fastpath is a mechanism that uses the network interface of an inbound request to send the response directly back to the MAC that sent the request, bypassing the routing table. By avoiding the routing table lookup, fastpath provides a quick access to data.
  • Clustered Data ONTAP 8.0 uses the SK stack and so does Data ONTAP 7G/ 7-Mode for networking. By default, the 'ip.fastpath' option is not configurable in Clustered Data ONTAP and is enabled by default in Clustered Data ONTAP 8.0.
  • Data ONTAP 8.3.1 and later allows for changing the ip.fastpath option from clustershell.
  • IP fastpath has been deprecated as of 9.2 and replaced by route caching.
