I have some 3560 Switches I threw in rack and configured up.
Everything was running well and then I installed a different image See below:
System image file is “flash:/c3560-ipservicesk9-mz.122-55.SE11.bin”
For this model this image is suppose to be good and indeed I installed it on both of my 3560 switches named 3560-1 and 3560-2.
When I came home today I could not telnet into 3560-2.
I made sure all my telnet ports where configured with passwords and login and that there was a secret password enabled.
I tested with pings which where fine. However I could still not telnet to the switch. I finally reloaded it but this did not solve the issue either. Next I sit the switch back to its original IOS and that also did not fix it as it had the same error.
Finally I deleted out the vlan.dat and the config.txt files and erased the configuration and installed the IPservice image back on (Which I verified when installing as well as checked hash for corruption) and started it up with no configure and I built it back up and once again everything looked good.
see some tests:
3560-1#ping 192.168.174.20
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.174.20, timeout is 2 seconds:
!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/4/9 ms
3560-1#telnet 192.168.174.20
Trying 192.168.174.20 …
% Connection refused by remote host
here is the config of the switch cannot telnet to(3560-2):
I removed most of the ports as they just distract.
