I have a MAX6000 with 48modems running TAOS8.0.1 Summary: Is there a way to turn off LCP echo requests and replies on the MAX6000 for PPP links which are up? Problem: We have a few, but very important, cellular users who connect at speeds of 9600bps but sometime based on coverage they can connect even at 2400bps. What we see if that for users connected at 2400bps, if they start a large file transfer, the MAX send a LCP termination after about 15k data transfer. Analyzing the PPP logs we see that the MAX sends out LCP echo requests every 5 seconds and expects a LCP echo reply within a 5 second timeout value. When a user is doing a large file data transfer, each 1500byte MTU takes about 5seconds at 2400bps. As a result, the LCP echo requests or replies sit pending behind these 1500byte MTUs and thus dont arrive in the 5 second timeout value. After about 15k bytes, the MAX has timed out on consecutively 3 to 4 LCP echo replies and drops the connection. When I change the MTU/MRU on the MAX to be something like 128bytes, the connection stays up proving the above theory. But this solution cannot work for long term because several websites having "Dont Fragment" bit turned on, and you can surf them using a 128bytes fragments. The RFC says that LCP echo requests and replies should not be necessary once the link has come up and PPP negotiation is complete. So it will be best to make the MAX turn off these requests. Any clues? Thanks! Prasanna. ++ Ascend Users Mailing List ++ To unsubscribe: send unsubscribe to ascend-users-request at bungi.com To get FAQ'd: <http://www.nealis.net/ascend/faq>
