The router supports redirection of IPv4 traffic arriving on a Layer 3 interface for ISA NAT processing. An OF controller can program NAT steering for H-OFS instances with the switch-defined-cookie command enabled using the following OF encoding:
flow_mod:
instruction type: OFPIT_WRITE_ACTIONS/OFPIT_APPLY_ACTION,
action type: OFPAT_OUTPUT,
The port uses SR OS LOGICAL port encoding as described in the SR OS H-OFS logical port section.
