Packet tagging in Ostinato

[ashok...@gmail.com]

Hi Experts,

Can you please let me know if Ostinato supports packet tagging? If yes, how?

Thanks in advance,

Warm regards,
Ashok

What do you mean by packet tagging?

You mean you want generated packets to have vlan tags? If so, just add
the vlan tag when selecting protocols when building a stream.

here is all I do (removing my packet building code)

        p = stream_id.protocol.add()

        p.protocol_id.id = ost_pb.Protocol.kVlanFieldNumber

        tag = p.Extensions[vlan]

        vlanInfo = 0

        changedVlan = False

        if vlan_id:

            vlanInfo = int(vlan_id)

            changedVlan = True

        if vlan_tci:

            vlanInfo |= int(vlan_tci) << 13

            changedVlan = True

        if changedVlan:

            tag.vlan_tag = vlanInfo

and for vlan stack packets:

        p = stream_id.protocol.add()

        p.protocol_id.id = ost_pb.Protocol.kVlanStackFieldNumber

        stack = p.Extensions[vlanStack]

        index = 0

        while index < vlan_num:

            index += 1

            p.protocol_id.id = ost_pb.Protocol.kVlanStackFieldNumber

            vlanInfo = 0

            changedVlan = False

            if vlan_id[index]:

                vlanInfo = int(vlan_id[index])

                changedVlan = True

            if vlan_tci[index]:

                vlanInfo |= int(vlan_tci[index]) << 13

                changedVlan = True

            if changedVlan:

                p.Extensions[svlan].vlan_tag = vlanInfo

Are you just doing ipv6 stuff? Are you emulating a protocol? This is on top of the 802.1q protocol? Or are you trying to do packet signature stuff like certain generators do to test qos/policy?
Ostinato doesn't have anything to do something like that which I know of. If you draw a picture or say more of what you want, I might be able to come up with some ideas.

Thanks Srivats and Aaron. I am actually looking at inserting some information like flow, port, id etc in the packet. Which I will check for at the receiving side for scoreboarding.

Warm regards,

See if the hexdump protocol or the userscript protocol can serve your needs.
