Hi, Gourav
Sorry for delaying.
Currently, no way is provided to ignore some layers (ethernet, ipv4,
etc...) for the switch test tool.
All you can do is ignoring whole packets at receiving end.
By following fix, you can do it:
diff --git a/ryu/tests/switch/tester.py b/ryu/tests/switch/tester.py
index f907555..56c84b6 100644
--- a/ryu/tests/switch/tester.py

- if isinstance(test[KEY_EGRESS], list):

- }
- }
- msg = ofproto_parser.ofp_msg_from_jsondict(
- tester_dp, mod)
- one[KEY_FLOW] = msg
- one[KEY_KBPS] = throughput.get(KEY_KBPS)
- one[KEY_PKTPS] = throughput.get(KEY_PKTPS)
- if not bool(one[KEY_KBPS]) != bool(one[KEY_PKTPS]):
- raise ValueError(
- '"%s" requires either "%s" or "%s".' % (
- KEY_THROUGHPUT, KEY_KBPS, KEY_PKTPS))
- throughputs.append(one)

Hi,
I am using RYU for unit testing Openflow based switch with a host
running as controller and a connected switch at auxilliary switch
(https://osrg.github.io/ryu-book/en/html/switch_test_tool.html)
I am running "ryu manager" with test cases in json files.
I want to know is there any way to ignore some packet content to parse
at receiving end.
Like,
"tests":[
{
"ingress":[
"ethernet(dst='22:22:22:22:22:22',
src='12:11:11:11:11:11', ethertype=2048)",
"ipv4(tos=32, proto=6, src='192.168.10.10',
dst='192.168.20.20', ttl=64)",
"tcp(dst_port=2222, option=bytes(b'\\x00' * 4),
src_port=11111)",
"b'\\x01\\x02\\x03\\x04\\x05\\x06\\x07\\x08\\t\\n\\x0b\\x0c\\r\\x0e\\x0f\\x10\\x11\\x12\\x13\\x14\\x15\\x16\\x17\\x18\\x19\\x1a\\x1b\\x1c\\x1d\\x1e\\x1f'"
],
"egress":[
*"ethernet(dst='22:22:21:22:21:22', src='12:11:11:11:11:11',
ethertype=33024)*",
*"vlan(ethertype=2048,pcp=0,vid=1)",*
*"ipv4(tos=32, proto=6, src='192.168.10.10', dst='192.168.20.20',
ttl=63)",*
"tcp(dst_port=2222, option=bytes(b'\\x00' * 4),
src_port=11111)",
"b'\\x01\\x02\\x03\\x04\\x05\\x06\\x07\\x08\\t\\n\\x0b\\x0c\\r\\x0e\\x0f\\x10\\x11\\x12\\x13\\x14\\x15\\x16\\x17\\x18\\x19\\x1a\\x1b\\x1c\\x1d\\x1e\\x1f'"
]
}
]
Is there any way that I can ignore(or don't care) the whole or partial
ethernet/vlan/ipv4/ipv6 packet content at receivng end as some of the
values can differ in different setup and I don't want to hard code it.
Please let me know if
Thanks and Regards,
Gourav Gopal
