Nicira Extension Actions Structures

The followings shows the supported NXAction classes in OF1.3, but also available in OF1.2+.

Nicira Extended Match Structures

The API of this class is the same as OFPMatch.

You can define the flow match by the keyword arguments. The following arguments are available.

Argument	Value	Description
eth_dst_nxm	MAC address	Ethernet destination address.
eth_src_nxm	MAC address	Ethernet source address.
tunnel_id_nxm	Integer 64bit	Tunnel identifier.
tun_ipv4_src	IPv4 address	Tunnel IPv4 source address.
tun_ipv4_dst	IPv4 address	Tunnel IPv4 destination address.
pkt_mark	Integer 32bit	Packet metadata mark.
conj_id	Integer 32bit	Conjunction ID used only with the conjunction action
ct_state	Integer 32bit	Conntrack state.
ct_zone	Integer 16bit	Conntrack zone.
ct_mark	Integer 32bit	Conntrack mark.
ct_label	Integer 128bit	Conntrack label.
_dp_hash	Integer 32bit	Flow hash computed in Datapath.
reg<idx>	Integer 32bit	Packet register. <idx> is register number 0-7.
