DLSW has to be listed twice in the access list because messages are both
coming in and going out. Look at the two top lines in that access list way
down at the bottom of this email. The first line covers packets from
anybody with a dlsw source port, bound for anybody, any destination port.
The second line covers packets from anywhere, any port, destined for dlsw.

Subject: RE: Custom queue-list for DLSW
Ok, did some testing. Take a look at the results. The top one is without the
priority keyword, and the second one is with the priority keyword. Looks
like priority keyword has to be used for port 1981, 1982, 1983 to be used.
Otherwise it's just port 2065.
Port 2067 seems like a port used for non cisco dlsw routers. This was from
looking at the archives.
But I'm also confused about why 2065 has to be included twice in the access
list for source and destination traffic.

David,
"dlsw" keyword is only for FST encapsulation, for TCP you need to specify
all
the ports involved.
