After tftp backup, telnet/ping works via switches only!!!

Hi

After backing up any of our 2960x edge switches to a tftp server, we become unable to telnet or ping the switch again from pc until rebooted. Switch remains pingable and can be accessed by telnet from any other switch (core or edge)!!!

Any idea about the cause?

Hello,

 

is the TFTP server the same as the PC you are trying to connect from ? Chances are that you have a hung session on the switch. Can you post the output of 'show sessions' and 'show users' from the switch when this problem occurs ?

Also post the output of 'show tcp tcb'...

yes, tftp server is on the same pc. but, does a hung session result in losing ping and telnet from pc to the switch while having them running from any other switch?

Possible...but it could also be a bug. In addition to the information requested, also post the output of 'show version'...
