Hi Ben, The ovs-dpctl command output does not show any skb_mark being set for the datapath flow:
# ovs-dpctl dump-flows skb_priority(0),in_port(4),eth(src=52:54:00:74:f9:41,dst=52:54:00:aa:93:9e),eth_type(0x0800),ipv4(src= 2.2.2.3/255.255.255.255,dst=2.2.2.2/255.255.255.255,proto=1/0xff,tos=0/0x3,ttl=64/0,frag=no/0xff),icmp(type=8,code=0), packets:3499, bytes:342902, used:0.571s, actions:set(tunnel(tun_id=0xde,src=0.0.0.0,dst=1.1.1.128,tos=0x0,ttl=64,flags(df,key))),2 Regards, Nirmal On Wed, Sep 17, 2014 at 10:50 PM, Ben Pfaff <b...@nicira.com> wrote: > On Wed, Sep 17, 2014 at 05:12:20PM +0530, Nirmalanand Jebakumar wrote: > > In this link below, I read that pkt_mark is supported as a MATCH field. > > Does OVS support pkt_mark as a SET action? > > Yes. > > > The command I ran is > > /usr/bin/ovs-ofctl add-flow -O Openflow13 br0 " > > hard_timeout=3600,idle_timeout=30,table=1,priority=10,cookie=2,in_port=3, > > > dl_type=0x800,nw_dst=2.2.2.2,dl_dst=52:54:00:aa:93:9e,actions=set_tunnel:222, > > set_field:1.1.1.128->tun_dst,set_field:222->pkt_mark,output:1" > > > > No errors were seen with the CLI and I see packet count getting > incremented > > for the flow in the dump-flows output: > > cookie=2, duration=33.059s, table=1, n_packets=34, n_bytes=3332, > > idle_timeout=30, hard_timeout=3600, > > priority=10,ip,in_port=3,dl_dst=52:54:00:aa:93:9e,nw_dst=2.2.2.2 > > actions=set_tunnel:0xde,load:0x1010180->NXM_NX_TUN_IPV4_DST[], > > load:0xde->NXM_NX_PKT_MARK[],output:1 > > > > Later, set the ToS & CoS using iptables command: > > iptables -I POSTROUTING -o eth1.1 -m mark --mark 222 -t mangle -j TOS > > --set-tos 104 > > > > iptables -I POSTROUTING -o eth1.1 -m mark --mark 222 -t mangle -j > CLASSIFY > > --set-class 0:2 > > > > But in the final packet, I do not notice any ToS/CoS values set? > > This is a situation where looking at the generated kernel datapath flows > would be helpful. In your above setup, please run "ovs-dpctl > dump-flows" while packets are passing through the flow, and look for > datapath flows that correspond to the OpenFlow flows above. Do the > datapath flows show pkt_mark (or skb_mark) being set? > _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
