How to handle DLSw for SDLC and token-ring to same remote peer

We have the need to have SDLC and token-ring connections from one local router to a the same remote site. Currently we have a remote peer for token-ring:

dlsw port-list 10 TokenRing0/0

dlsw remote-peer 10 tcp a.b.c.d lf 1500

We have an SDLC link on a serial port. I understand that SDLC is part of group 0. How do I also get the SDLC traffic to the same remote peer? Is it as simple as adding another remote peer statement to the same IP?

dlsw remote-peer 0 tcp a.b.c.d lf 1500

Re: How to handle DLSw for SDLC and token-ring to same remote pe

Hi,

you can have only one dlsw peer between two given routers. If you have already a dlsw peer between router a and router b using portlist 10 for this one you can NOT add another peer with a different portlist to the same remote router.

You can try to add your serial port to portlist 10, that should normaly do the trick. I have never used it but the configuration allows tokenring, ethernet and serial interfaces.

Something like this:

dlsw port-list 10 TokenRing1/1 Serial3/3

Re: How to handle DLSw for SDLC and token-ring to same remote pe

Do you have your token ring configuration complete to bridge to DLSW ?

for example;

!

source-bridge ring-group 2000

dlsw local-peer peer-id 150.150.10.1

dlsw remote-peer 0 tcp 150.150.10.2

!

interface loopback 0

ip address 150.150.10.1 255.255.255.0

!

interface serial 0

ip address 150.150.11.1 255.255.255.192

!

interface serial 1

description PU2 with SDLC station role set to secondary

no ip address

encapsulation sdlc

no keepalive

clockrate 9600

sdlc role primary

sdlc vmac 4000.9999.0100

sdlc address 01

sdlc xid 01 05d20006

sdlc partner 4000.1020.1000 01

sdlc dlsw 1

!

interface serial 2

description Node Type 2.1 with SDLC station role set to negotiable or primary

encapsulation sdlc

sdlc role prim-xid-poll

sdlc vmac 1234.3174.0000

sdlc address d2

sdlc partner 1000.5aed.1f53 d2

sdlc dlsw d2

!

interface tokenring 0

no ip address

ring-speed 16

source-bridge 100 1 2000

source-bridge spanning

!

If your SDLC link is working through DLSW (it is in DLSW ring group 10 according to your first configuration statement and port list statement and must match at both ends), it should be an easy modification to add the token ring configuration to join the bridge to the remote DLSW router.

See;
