we have a cisco 2960 switch which became unresponsible, no reply to pings or telnet.
when we consoled into the switch we could not type anything in and got a strange output from the switch of just 12,1,12,1,12,12 keep coming up even when we did not type anything in as well.
We had to reboot the switch and everything was ok after that.
the version is flash:c2960-lanbase-mz.122-35.SE5/c2960-lanbase-mz.122-35.SE5.bin
anyone seen anything like that before?
