matching Ip_dscp in hp aruba 3810m openflow 1.3 switch

I am trying to match the ip_dscp field using ryu controller i have made a small modification to the simple_switch_13.py app in ryu. it worked fine when i tried in mininet with openflow13 switch but it wont match ip_dscp when i used Hp aruba 3810m switch.  i have included the ryu app and flow tables for hp and openflow13 switch below.

Thanks

here is the modified simple_switch_13.py app i am using:

class SimpleSwitch13(app_manager.RyuApp):
OFP_VERSIONS = [ofproto_v1_3.OFP_VERSION]

def __init__(self, *args, **kwargs):
super(SimpleSwitch13, self).__init__(*args, **kwargs)
self.mac_to_port = {}

@SET_ev_cls(ofp_event.EventOFPSwitchFeatures, CONFIG_DISPATCHER)
def switch_features_handler(self, ev):
datapath = ev.msg.datapath
ofproto = datapath.ofproto
parser = datapath.ofproto_parser

# install table-miss flow entry
#
# We specify NO BUFFER to max_len of the output action due to
# OVS bug. At this moment, if we specify a lesser number, e.g.,
# 128, OVS will send Packet-In with invalid buffer_id and
# truncated packet data. In that case, we cannot output packets
# correctly. The bug has been fixed in OVS v2.1.0.
match = parser.OFPMatch()
actions = [parser.OFPActionOutput(ofproto.OFPP_CONTROLLER,
ofproto.OFPCML_NO_BUFFER)]
self.add_flow(datapath, 0, match, actions)

def add_flow(self, datapath, priority, match, actions, buffer_id=None):
ofproto = datapath.ofproto
parser = datapath.ofproto_parser

inst = [parser.OFPInstructionActions(ofproto.OFPIT_APPLY_ACTIONS,
actions)]
if buffer_id:
mod = parser.OFPFlowMod(datapath=datapath, table_id=200, buffer_id=buffer_id,

else:
mod = parser.OFPFlowMod(datapath=datapath, table_id=200, priority=priority,
match=match, instructions=inst)
datapath.send_msg(mod)

@SET_ev_cls(ofp_event.EventOFPPacketIn, MAIN_DISPATCHER)
def _packet_in_handler(self, ev):
# If you hit this you might want to increase
# the "miss_send_length" of your switch
if ev.msg.msg_len < ev.msg.total_len:
self.logger.debug("packet truncated: only %s of %s bytes",
ev.msg.msg_len, ev.msg.total_len)

return

self.mac_to_port.setdefault(dpid, {})

self.logger.info("packet in %s %s %s %s", dpid, src, dst, in_port)

# learn a mac address to avoid FLOOD next time.
self.mac_to_port[dpid][src] = in_port

if dst in self.mac_to_port[dpid]:
out_port = self.mac_to_port[dpid][dst]
else:
out_port = ofproto.OFPP_FLOOD

actions = [parser.OFPActionOutput(out_port)]
arp_pkt = pkt.get_protocol(arp.arp)

 

# install a flow to avoid packet_in next time
if out_port != ofproto.OFPP_FLOOD:


if arp_pkt:
match = parser.OFPMatch( in_port=in_port, eth_src=src)

elif ip_dscp is not None and ip_dscp != 0:

 

match = parser.OFPMatch( eth_type=0x0800,ipv4_src=ip_pkt.src, ipv4_dst=ip_pkt.dst, ip_dscp=ip_dscp)

 

else:

match = parser.OFPMatch( eth_type=0x0800, ipv4_src=ip_pkt.src, ipv4_dst=ip_pkt.dst)

 

# verify if we have a valid buffer_id, if yes avoid to send both
# flow_mod & packet_out
if msg.buffer_id != ofproto.OFP_NO_BUFFER:
self.add_flow(datapath, 1, match, actions, msg.buffer_id)
return
else:
self.add_flow(datapath, 1, match, actions)
data = None
if msg.buffer_id == ofproto.OFP_NO_BUFFER:
data = msg.data

out = parser.OFPPacketOut(datapath=datapath, buffer_id=msg.buffer_id,
in_port=in_port, actions=actions, data=data)
datapath.send_msg(out)

This is the flow table when i used in mininet: you can see its matching difference ip_dscp values

Re: matching Ip_dscp in hp aruba 3810m openflow 1.3 switch

Hi soginy914,

I see the issue you're raising, that you're pushing multiple flows (which match IP DSCP 10, 40, 42) but only a single flow is entered into the hardware table (flows 4 and 5). I have two requests for more information:

  1. Could you enable OpenFlow debug output on the 3810 with the commands "debug openflow" and "debug destination session" and then run through these steps? This may give us some additional information to find out why the behavior differs from what's expected.
  2. Could you post the firmware version you're using? We'd recommend 16.04 firmware since that would have the latest fixes.

Re: matching Ip_dscp in hp aruba 3810m openflow 1.3 switch

Hi thanks for the response i have provided the information below. What i have also observed is that the switch doesnot seem to match the ip_dscp field when i try to print the dscp value i get None. the switch adminstrator guide seem to suggest that the switch supports matching dscp. Can you confirm if it through does support matching dscp.

 

Regards
