Hi
I havent been yet successful in re-establishing the wirefilter as yet when
you kill it.i iam using the same procedure as described in my previous mail
below.I noted something that when you create a double wirefilter in xml i.e
host 1 attached to both OF 1 and OF 2, by adding the code ,BELOWthe OF 1
wirefilter code the hosts ping but as soon as you delete the wire filter
attached to OF 1, the pings stop although the host is still connected to OF 2.
But if u add this code above OF 1 than the ping continue after deleting OF1 but
ends when deleting OF2. I have also tried deleting both wirefilter and then
creating them but it attaches to the same OF switch that is above the other in
the code.
So how do i create a new wirefilter after killing the old one.
What do you mean by checking the flow entries of the switches???By switches you
mean Openflow switches and kindly explain what is the procedure to check them???
Regard
Ali
