Don ,
You can use routers to create llc sessions over DLSw .
There is a feature called DSPU .
Let's say you have the following topology ;
router1--eth--router=====router--eth--router2
<---DLSw--->
router1 will be DSPU PU ;
router1#(config)
router1#(config)dspu default-pu
router1#(config)interface Ethernet0/0
router1#(config-if)
router1#(config-if)dspu enable-pu lsap 4
router2 DSPU host ;
router2(config)dspu host FLEMISH xid-snd 00000000 rmac
0030.94ba.c820 rsap 4 lsap 4 interface Ethernet0/0
router2#(config)interface Ethernet0/0
router2#(config-if)dspu enable-host lsap 4
router2#(config-if)dspu start FLEMISH
The rmac address in the dspu host line is the MAC of
the ethernet interface on router1 .
( As you know there are two things inportant to set up
the llc2 session , MAC/SAP pair :-)
check the config with ;
router#sh dspu
dspu pu DFLT0001 Ethernet0/0 PU STATUS Active
FRAMES RECEIVED 1 FRAMES SENT 1
LUs USED BY DSPU 0 LUs ACTIVE 0
LUs USED BY API 0 LUs ACTIVE 0
LUs ACTIVATED BY HOST BUT NOT USED 0
router#sh llc
LLC2 Connections: total of 1 connections
Ethernet0/0 DTE: 0030.94ba.c900 0030.94ba.c820 04 04
state NORMAL
V(S)=1, V(R)=1, Last N(R)=1, Local window=7, Remote
Window=127
akmax=7, n2=8,
xid-retry timer 0/0 ack timer
0/1000
p timer 0/1000 idle timer
9600/10000
rej timer 0/3200 busy timer
0/9600
akdelay timer 0/100 txQ count
0/200
router#
This is also good to test SAP filters . You can create
multiple sessions all with different lsap/rsap values
.

This will not get into DLSw .
Only native netbios,SNA traffic are picked up by DLSW
.
( it is possible to get ip into dlsw to bridge it
accross a wan , but this is not why you should use
DLSw )
