[OPNFLWPLUG-452] ICMPv4 type/code in OF10 match are ignored.

Mon, 27 Sep 2021 09:01:32 +0000

Although OF10 supports ICMP type/code match, openflowplugin always ignores icmpv4-match in MD-SAL match if OF protocol is OF10.

I tried to install a flow entry which drops ICMPv4 echo into OF10 switch.

{ "ip-protocol": 1 }

,
"icmpv4-match":

{ "icmpv4-type": 8, "icmpv4-code": 0 }

,
"ethernet-match": {
"ethernet-type":

{ "type": 2048 }

}
}
}
]
}

But both ICMP type and code were ignored.

mininet> dpctl dump-flows

    NXST_FLOW reply (xid=0x4):
    cookie=0x0, duration=68.873s, table=0, n_packets=0, n_bytes=0, idle_age=68, priority=10,icmp actions=drop

ICMP type and code should be set as TP_SRC/TP_DST respectively into OF10 match like this.
