I hv cisco 2621 router frm its etthernet it's converted into E-1 (T-1 in USA ) then fiber optics again after almost 1200 km it is converted into ethernet frm E-1. but while i m putting real traffic in this link i m getting intermediant drops at the second end. i hv conneted this ethernet convertor to Cisco 2950 switch, in this switch one pc is connected to monitor this link continously. Problem is that the drops not being captured while pinging frm one end pc to other end. but its giving drops after 2950 switch. this switch is L-2 purpose only i.e. no vlans. I hv the que. that whether i should do some addition configuration of the ethernet of my 2621 router bcoz this is travelling to some 1200 km.
Pls suggest. ur quick response will help me very much.
