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.
