Connmark retriever action in tc(8)                                     Linux                                    Connmark retriever action in tc(8)

NAME

       connmark - netfilter connmark retriever action

SYNOPSIS

       tc ... action connmark [ zone u16_zone_index ] [ CONTROL ] [ index u32_index ]

       CONTROL := { reclassify | pipe | drop | continue | ok }

DESCRIPTION

       The connmark action is used to restore the connection's mark value into the packet's fwmark.

OPTIONS

       zone u16_zone_index
              Specify the conntrack zone when doing conntrack lookups for packets.  u16_zone_index is a 16bit unsigned decimal value.

       CONTROL
              How to continue after executing this action.

              reclassify
                     Restarts classification by jumping back to the first filter attached to this action's parent.

              pipe   Continue with the next action, this is the default.

              drop
              shot   Packet will be dropped without running further actions.

              continue
                     Continue classification with next filter in line.

              pass   Return to calling qdisc for packet processing. This ends the classification process.

       index u32_index
              Specify  an  index  for  this action in order to being able to identify it in later commands.  u32_index is a 32bit unsigned decimal
              value.
