I am using Openswitch but I have realized it is not supported reassembling "OFPC_IP_REASM". I am looking for a switch support OFPC_IP_REASM which switch supports reassemble?
I did some tests with several switch vendors such as HP, Brocade, Cisco or even Mininet and for all switches, OFPC_IP_REASM property is set to false as i saw in the trace files.
When I search for some information from vendor's web sites some of them says that they don't support this property.
For example, this is the documentation of HPE, it says:
HP switches support OpenFlow Switch Specification, version 1.3.1
Unsupported features:
Handling of IP Fragments: OFPC_IP_REASM/OFPC_FRAG_REASM
HP switches support OpenFlow Switch Specification, version 1.0.0
Unsupported features:
Handling of IP Fragments: OFPC_IP_REASM/OFPC_FRAG_REASM.
For Juniper, there is a complication. In this page, they say:
Junos OS Support for OpenFlow v1.3.1 Features Reply Messages
OFPC_IP_REASM Supported (for MX Series, EX9200, QFX5100 and EX4600)
But in this page for same models they say:
Junos OS Support for OpenFlow v1.3.1 Features Reply Messages
OFPC_IP_REASM Not supported
If you familier with C/C++, you can look the source code of Open vSwitch. I don't know if it is possible but maybe you can manipulate this property from source code.
