Dear Sir/Madam,
I'm trying to drop packets that match an IP address using this code
> class RuleBase(object):
> def __init__(self, dp: Datapath, *args, **kwargs):
> self.dp = dp
> self.ofproto = self.dp.ofproto
> self.parser = self.dp.ofproto_parser
> self.match = kwargs
> self.inst = []
>
> def add_flow(self):
> match = self.parser.OFPMatch(**self.match)
> msg = self.parser.OFPFlowMod(
> table_id=FIREWALL_TABLE_ID,
> datapath=self.dp,
> priority=10,
> command=self.ofproto.OFPFC_ADD,
> match=match,
> instructions=self.inst
> )
> self.dp.send_msg(msg)
>
>
> class DenyRule(RuleBase):
> def __init__(self, *args, **kwargs):
> super(DenyRule, self).__init__(*args, **kwargs)
> self.inst = [
>
self.parser.OFPInstructionActions(self.ofproto.OFPIT_APPLY_ACTIONS, [])
> ]
I'm using it in switch_features_handler as follows:
> msg = ev.msg
> dp = msg.datapath
> d_rule = DenyRule(dp=dp, ipv6_dst='2001:db8:bd05:1d2:288a:1fc0:1:10ee')
> d_rule.add_flow()
But, I get the following output:
move onto main mode
EventOFPErrorMsg received.

`-- msg_type: OFPT_ERROR(1)
