OFPFMFC_EPERM error = permission denied on 2920 switch

openflow — Thu, 05 Dec 2013 05:29:41 GMT

Hi all

I am trying to run oft tests on HP switch 2920 . My set up details are as follows :

192.168.2.240( oft machine ) eth2 --------------------------------- 3 (HP SWITCH 2920 port) 192.168.3.130

eth3 -----------------------------------5

eth4 -----------------------------------7

eth5 --------------------------------- 9

I have added a flow to the switch which we can see in the flow table of my openflow instance , which i named testing .

By command : # show openflow instance testing flows

i can see the flows .

But when i try to delete the same flow from the switch , it is giving OFPFMFC_EPERM error which says permission denied according to openflow specification. I think that their is some authentication with the swich which is not allowing flows to delete .

Please guide me the solution so that i can delete flows without this error .

Thanks for your query.

Are you still facing the permission denied issue?

Please see try setting the Table id->100
