I have two Ethernet segments and pair of DLSW+ routers between them. I would like to implement traffic classification, but all my traffic flows through high or low priority queues. Why ?
sap-priority-list 1 normal smac 0000.3049.d7f0
dlsw local-peer peer-id 172.16.1.1
dlsw remote-peer 0 tcp 172.16.1.3 priority
dlsw bridge-group 1 sap-priority 1
R1#sho dlsw pe
Peers: state pkts_rx pkts_tx type drops ckts TCP uptime
TCP 172.16.1.3
High priority CONNECT 4627 359 conf 0 1 0 00:25:00
Medium priority CONNECT 0 0 conf 0 - 0 00:25:00
Normal priority CONNECT 0 0 conf 0 - 0 00:25:00
Low priority CONNECT 8 6 conf 0 - 0 00:25:00
Total number of connected peers: 1
Total number of connections: 4
Many thanks.
P.S. 0000.3049.d7f0 (noncanonical format) is MAC address of Ethernet connected host.

It's kind of hard to tell if there's a problem from the information you included. Your configuration looks ok.
Are you sure there was data traffic sent from the mac address you configured?
Other traffic (sabme, keep-alives) besides actual data traffic will still be sent over the high priority connection.
I'd suggest starting a session and sending some data traffic and look closely at the results. If you still see a problem, open a case with the TAC and give them more info - sh dlsw circuit detail, etc.

For data traffic generation I use IPX & IP ping. It's not real SNA traffic, but it is the best I can get. There are no errors in MAC address because only one device is connected to Ethernet port on R1 and I see this MAC in show dlsw reachability local.

I think the problem is with the type of traffic you are using to test. DLSW will always send it own control traffic as high priority and explorers as low priority. Becaus IPX traffic is not supported by DLSW, only the contol and explorer traffic will ever be sent. This is why the circuit only ever gets as far as CKT_ESTABLISHED and never goes to CONNECTED.
