One of my Cisco 3750 stack does not give any login prompt while I try to telnet into it. At first I thought, the number of users logged in must have crossed the limits but when I tried to login through console as well, it showed the same problem sign. Even in console screen it keeps saying "Switch con0 is now available: Press RETURN to get started". When I hit enter it seems to show some prompt for a fraction of second then again shows the above message. While I try to telnet on its IP, it just goes blank and hitting enter one more time returns the screen back to original. I am using CMD for telnet.
Any ideas why is it happening? Is it possible that it is too busy to accept new telnet connection but still everything (every other communication) working just fine with no problem.
Thanks in advance,
