[ovs-discuss] OFP v1.3 match normalisation & set field syntax

[Wenqin SHAO]

Hi list,

New to here, and I encountered some seem-to-be-very-basic problems
concerning flow installation. Here it goes:

First, it's about matching normalisation, I tried to install a rule
manually via ovs-ofctl.

sudo ovs-ofctl -O OpenFlow13 add-flow s1
dl_src=00:00:00:00:aa:bb,dl_dst=aa:aa:00:00:00:00,nw_src=192.168.0.1,nw_dst=8.8.8.8,tp_src=7788,actions=output:1
2014-07-28T09:40:16Z|00001|ofp_util|INFO|normalization changed ofp_match,
details:
2014-07-28T09:40:16Z|00002|ofp_util|INFO| pre:
dl_src=00:00:00:00:aa:bb,dl_dst=aa:aa:00:00:00:00,nw_src=192.168.0.1,nw_dst=8.8.8.8,tp_src=7788

I was informed that the matching has been normalised. As we can see, only
the datalink part of the matching is conserved. It must be more than a
simple normalisation, I'd say. I'd appreciate explanation on that.

Second issues comes with the use of set_filed option while formulating
actions:

sudo ovs-ofctl -O OpenFlow13 add-flow s1
actions=set_field:01:02:03:04:05:06->dl_dst,output:1
ovs-ofctl: 01:02:03:04:05:06-: missing `->'

I didn't see how I could miss the ->...

Hoping someone could point out the silly mistakes I've made, I thank you
all in advance.


Sincerely,
