Vanguard acting as PU 1 to PU 2.1 application gateway?

Vanguard acting as PU 1 to PU 2.1 application gateway?

Vanguard acting as PU 1 to PU 2.1 application gateway?

Hello All!

I am trying to migrate an existing SNA IBM 5294 Controller/Vanguard 320/Frame-Relay/Vanguard 7310/AS400 installation to a Cisco DLSW solution.

I have run into an issue where the controller attached to the Vanguard 320 appears to be a PU 1, but the AS400 has the controller description set as if it was a PU 2.1.  

Is it possible that the Vanguard equipment is somehow acting as a PU 2.1 to PU 1 application gateway?

I have been able to bridge traffic between the AS400 and the controller, but when I see broadcast XID frames from the AS400 reach the controller, it seems to respond with PU 1 XID frames.

RE: Vanguard acting as PU 1 to PU 2.1 application gateway?

HI, you may be able to play with the QLLC option in the TPAD port/station configuration to get this to work. However, doubtful, since this part of the configuration is normally done in the SDLC-LLC conversion table (which would be in the 7310).
