Oops.. Looks like I inadvertently dropped ryu-devel from the thread.. So below was correspondence between Gandhimathi and I (Ali). Feel free to provide feedback...
### Gandhimathi ### Have you tried with set_field()? page 167 from https://media.readthedocs.org/pdf/ryu/latest/ryu.pdf ### Ali ### I've tried the following which works fine: match = parser.OFPMatch(eth_dst="02:a3:33:b2:2d:21") However, for my particular test case, I've got match conditions stored in a config file and when a switch starts up, I read the config file and install flows in the switch. Now my config file has things like: inport = 1 eth_src = "None" eth_dst = "02:a3:33:b2:2d:21" And in my ryu application, I do something like (pseudo code): match = parser.OFPMatch() if inport != "None": match.append_field(ofproto.OXM_OF_IN_PORT, inport) if eth_src != "None": match.append_field(ofproto.OXM_OF_ETH_SRC, eth_src) if eth_dst != "None": match.append_field(ofproto.OXM_OF_ETH_SRC, eth_dst) print "match:", match match: 1, 02:a3:33:b2:2d:21 So if I don't have a value for a match condition (such as eth_src), I insert "None" in the config file. Then when I create my match, if "None" shows up for this parameter (like for eth_src), I don't add it to the match condition. The the point here is that I append fields (inport, eth_src etc) to the match condition iteratively. Hence, I can't use the form"match = parser.OFPMatch(eth_dst="02:a3:33:b2:2d:21"" ### Gandhimathi ### I understand what you are trying to do. May be the syntax you are using with match. append_field() is not correct? could you please, refer here: https://github.com/FlowForwarding/LINC-Switch/commit/4c9aa3ad5ad1250f8357e04a65773b409fbe4b4c. They used pointer data type to pass in append_field() method. ### Ali ### Per your suggest, below is what I attempted: match = parser.OFPMatch() test=[(ofproto.OXM_OF_IN_PORT,4),(ofproto.OXM_OF_ETH_SRC,"02:a3:33:b2:2d:21")] for a in test: match.append_field(*a) print "matching:", match matching: OFPMatch(oxm_fields={'eth_src': '30:32:3a:61:33:3a', 'in_port': 4}) As shown, the mac address still has the same weird format as before I also tried the following: match = parser.OFPMatch() match.set_in_port(4) match.set_dl_src("02:a3:33:b2:2d:21") print "matching:", match matching: OFPMatch(oxm_fields={}) But as shown, the output is empty REF: https://github.com/osrg/ryu/blob/master/ryu/app/rest_router.py#L1722 On Fri, Aug 14, 2015 at 2:13 PM, A Sydney <asydney...@gmail.com> wrote: > Any feedback? > > On Wed, Aug 12, 2015 at 5:29 PM, A Sydney <asydney...@gmail.com> wrote: > >> Hi Ryu folks, >> This may be a trivial question... >> >> I'm using ryu 3.23.2 on CentOS 6.6 (OF 1.3).
