Hello All,

The following MPLS flow successfully triggers hardware flow installation:

OFPST_FLOW reply (OF1.3) (xid=0x2):

cookie=0x0, duration=22.169s, table=0, n_packets=0, n_bytes=0,
ip,in_port=1,dl_vlan=1,nw_src=10.8.1.1,nw_dst=10.8.1.3
actions=push_mpls:0x8847,set_field:1000001->mpls_label,output:5

Note: I have installed the above flow manually through the P3922 switch CLI.



However, there are some issues when I am trying to install the above flow
through OpenDaylight REST API on to the physical switch (i.e. it does not
trigger the installation of the above hardware flow).

Here is the installed flow using OpenDaylight REST API:

OFPST_FLOW reply (OF1.3) (xid=0x2):

 cookie=0x191, duration=8.339s, table=0, n_packets=0, n_bytes=0,
send_flow_rem ip,in_port=1,dl_vlan=1,nw_src=10.8.1.1,nw_dst=10.8.1.3
actions=push_mpls:0x8847,set_field:1000001->mpls_label,output:5


Somehow, I think, I was able to install only a software flow by using the
OpenDaylight REST API.

If you compare the above two installed flows, the flow installed through
Opendaylight REST API has a additional parameter called ¨send_flow_rem¨,
does this parameter mean that this flow is a software flow ?

Let me know your thoughts and suggestions for the same.
