I am facing a very strange problem currently.....i have two sites A and B .............on Site A i have a LAN switch cisco 2950 connected to site B's switch via a radio link(Redliner something) .Now the problem is that when i ping test the both sites via attaching laptops on both sites A & B my ping is fine while when i connect the switches on both sites and then test ping From site A to B then i get some drops ....Can anyone have some clue.???
We have a similar setup for one of our clients, we have a site A - B and then from site B to a mini site we have Cisco 3750 switch connected via a wireless radio link.
We had similar issues whereby we receive lots of packet drops between site B and the mini site over the wireless link.
We logged an incident with our wireless service provider and they came in a few times and aligned the radio's etc eventually until the problem was resolved.
Hope this helps, unless you can explain the connectivity methods in detail.
