hi,
so during the vc i missed the point, that my sw router uplinks over mpls and
sgt and none of these are handled in the set parts yet...
without these, the stuff works as expected:
the first 10 packets from 5555::6 comes in as flow label 0,
the packets 10-20 from 5555::6 comes in as flowlabel 0x3039 that is 12345,
and packets 20-30 from 5555::6 comes in as flowlabel 0xd431 that is 54321...
and it's completely optional to have anything in the match statements, i mean,
a dumb acl who matches everything will do the trick, then you can do port
based
(re)marking... if that helps you, we can easily have this functionality in hw
less than a week.... :)
br,
cs
