Hello all,


We have an old router that did encapsulation DLSW for an application that used to use SNA server.

Sh dlsw peers shows that the tunnel is up but i don't want if it's still use.

I would like to remove this router but wants to be sure that nobody in my company still use this old application.

Thanks for your help

Hello Hatim,

to understand if it is really used use:


show dlsw circuit


Actually, if this show is empty it is not in use.


Hope to help

Thanks Giuseppe for your reply.

It was my first conclusion as this is empty but i was uncertained due to the command :

show dlsw reachability that show mac-address who found the remote peers :


000.7999.1248 UNCONFIRM REMOTE 172.18.253.1(2065)

4000.7999.1438 UNCONFIRM REMOTE 172.18.253.1(2065)

4000.7999.1468 UNCONFIRM REMOTE 172.18.253.1(2065)

4000.7999.2002 FOUND REMOTE 172.18.253.1(2065)

4000.7999.2003 FOUND REMOTE 172.18.253.1(2065)

4000.7999.2222 UNCONFIRM REMOTE 172.18.253.1(2065)

Hello Hatim,

the ouput of sh dlsw mac reachability can be influenced by messages sent by the remote router that could be configured to advertise reachability of one or more MAC addresses in order to reduce the explorer traffic on the WAN.

If it is possible for you I would access the remote router and give a look at dlsw configuration to see if there's any icanreach command that could appear in the output of the local router.

As we both agreed on previuos post if there is real activity the sh dlsw circ shouldn't be empty.

If you cannot access the remote router ask to its network administrator.


Hope to help

Giuseppe
