Hi. I appear to have had an issue where the following has arisen on an ATM point-to-point:-
Cisco 2821 with VWIC2-1MFT-T1/E1
******************************************
vbr-nrt 1920 1920
Cisco 7206vxr with ATM WAN OC3
*****************************************
vbr-nrt 1920 1920 50
Now the 2821 end wont allow you to add the burst (MBS) but the 7206 end will.
With this setup we then get traffic issues where the customer says they are only able to get 56kbps out of the link. The ATM product team says it shouldn't matter, but if you then make the 7206 end 1920 1920 (removing the 50) the connection works fine.
Can anyone please confirm that what we've experienced is caused by the vbr-nrt burst sizes not matching at either end, or shouldn't it matter as the ATM product team suggest.
Many thanks
