SNASW problem with a sna-server having six pu

[rrsstefano]

Hi all,

on a remote site we have a sna-server with 6 sna-sessions using a different sap value for each one.

From this site there is a dlsw connection to a central DLSW/SNASW router.

The problem is that the sna-server is able to open only two sna sessions then on the central router appear the messages

Aug 24 18:43:26: %SNASW-3-CS_LOG_11: PROBLEM - 51455 - Parallel TGs not supported to this adjacent node

Enabling a second dlsw peering on a second snasw router, the session opened are 4, then also on the second snasw router appears the error message.

IN the old network topology, where all was dlsw with CIP connection, there was no problem to open all six session.

There some limitations on snasw?

thanks

Hi,

when you say using a different sap value. Do you mean a different source sap or a different destination sap?

If you have different destination sap's than you need to configure multiple snasw ports with different local saps. The destination sap of the sna server is the local sap of the snasw port. The default local sap of the snasw port is 4.

Hi,

we different source sap, while the destinations sap is 04

Thanks

The CS_LOG_11 error message indicates that the downstream link does not support parallel TGs, based on the XID3 that SNASw received from the downstream sna server.

Please provide the snasw portion of the router config.

You can give a try using "conntype len" option on the snasw port.

thanks for feedbacks!!

I think we need to see the XID exchange as well as the connection attempts (captured with snasw dlc trace and pdlog) and the config of your set up.

I would suggest that you contact the Cisco TAC to open a service request; they will be able to assist you to collect the doc. Feel free to let them know that you conversed with me on this forum.

Thanks,

Hi Tran,

thanks for suggest.

I opened a service request and this evening we will test capturing dlsctrace and so on
