Thanks for the Email.
`The dlsw, rsrb, and stun keywords refer only to direct encapsulation.`
Any idea about FST?
Fast Sequenced Transport. Connectionless, sequenced transport protocol
that runs on top of the IP protocol. SRB traffic is encapsulated inside
of IP datagrams and is passed over an FST connection between two network
devices (such as routers). Speeds up data delivery, reduces overhead,
and improves the response time of SRB traffic.
I checked google and Groupstudy archives.
Can't find an fst protocol number nor a port.
I might have break out my sniffer. It might be tcp 2065 and they just
highjacked the frames for fst's use. I have no idea.

I think it refers to direct encapsulation, not to FST encapsulation (see
a
note at the very end of the example section under
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/
fqos
_r/qrfcmd6.htm#1036440).
Otherwise I agree with Scott, it is a common mistake and will do no good
for
TCP encapsulation.
Best regards,
Alexei

That's a common mistake... This use of "dlsw" as a protocol refers to
FST
encapsulation. Doesn't do anything for TCP encapsulation.
FST isn't really tied to UDP or TCP, it's kind of it's own little IP
sub-protocol.
The nomenclature could be a little more useful, and that would avoid
plenty
of confusion... But I guess that would also take all the fun out of it!

Hi Scott, thank you for your response.
What's up with this? The requirement was to use a priority-list for
dlsw
transit traffic between peers.
I did.
priority-list 1 protocol ip high tcp 2065
The solution shows
priority-list 1 protocol dlsw high
Ok, what port(s) does this command cover? I have a very hard time
believing
it is doing some level 4 check, which means just has to be doing some
ports.
TCP 2065, 1981-1983, what about fst? I'm guessing that fst is an udp
rtp
protocol. In fact I don't think I've ever seen a reference to fst being
a
protocol or udp port.
It bugs me because dlsw isn't a protocol like ipx or appletalk, it
shouldn't
be listed this way. It could be the local dlsw layer 2 stuff on the lan
interface, but that wouldn't apply to transit remote peer traffic.
Thanks in advance,
Michael

The ports 1981, 1982 and 1983 are ONLY involved when you are using the
"priority" feature. Otherwise, in a standard configuration, 2065 is the
only one used. You'll just have to figure out which direction your
connection is going! :)

I'm trying to figure out which port numbers I need just for normal tcp
dlsw
traffic.
Is it safe to say that 2065 and 1982 is the only ones needed for normal
dlsw
configs?
priority
(Optional) Enables prioritization features for this remote peer. Valid
TCP
port numbers are the following: . High-2065 . Medium-1981 . Normal-1982
.
Low-1983
