X25 interface: incoming QLLC to DLSW and other incoming X25 to XOT session


we would like to implement this kind of configuration in order to get DLSW transport for QLLC/X25 traffic and XOT for other X25 traffic:


source-bridge ring-group 999

dlsw local-peer peer-id

dlsw remote-peer 0 tcp

dlsw remote-peer 0 tcp


interface Serial1/1

encapsulation x25

x25 address 3110212011

x25 map qllc 1000.0000.0001 31104150101

qllc dlsw partner 4000.1611.1234


x25 route ^1$ xot xot-source Serial1/1

x25 route ^2$ xot xot-source Serial1/1


- Could anyone confirm that QLLC dlsw statement will take precedence over X25 routes?


For example:

If QLLC traffic is received on serial 1/1, will it be forwarded out to DLSW in 100% of the case or depending of X25 destination address, could it be routed to XOT peer?


I did not find any document on CCO that confirm this even if it seems quite obvious.


If someone had some documentation links regarding this, it would be really welcome.

Many thanks.

Re: X25 interface: incoming QLLC to DLSW and other incoming X25


i am not really sure what exactly u want to do.

what i configured is the following:

i have a about 100 x25 enddevice who want to connect

a ibm host via x25/qllc.

but we only have an ip network.

so i did the following:

i connected the x25 enddevice in the branch to a cisco router on a serial interface (enc x25).

then we forward this x25 call over xot to a cisco 7206.

there i forward the xot over a x25 loop on the same router to a x25 interface on which we do a x25 to llc


then we forward this llc connection over dlsw to a cannel attached cisco router which has a escon connection to our host.

if you need any further infos - let me know
