I have quite strange problem. First I'll explain shortly before going to details.
I have 2 PCs having 2 adapters connected to 2 switches.
PC1 port 1 - 10.220.16.126
Port 2 - 10.220.17.126
PC2 port 1 - 10.220.16.127
Port 2 - 10.220.17.127
I can ping from both sides using first subnet (16) but I cannot ping PC2 through the second subnet (17) - I loose about 80% pings.
What's the most strange for me is this:
While I try to ping from PC3 (my laptop) I'm successful if I'm out of that network - connected to some higher level switch - to both PCs and both ports.
But once I connect to that switch and set up appropriate IP (10.220.xx.125) - I can ping both PCs in subnet 16 but I "can't" ping PC2 in subnet 17 (10.220.17.127) and I'm getting timeout in approx 80% pings, some of them make it through though...
What could be the reason that I can easily ping both PCs while I'm out of that network (connected to switch which is far away from the switch nearby PCs and in different subnet) but I'm getting so many timeouts while pinging PC2 while I'm in same subnet??
I exchanged the PC2 and reimage it- no help. I used another switch just to make sure and got exactly the same results - once I'm connected in the same subnet I can't stable ping PC2 repeatedly.
Thanks for any ideas.
