The error may have appeared

The gibberish characters may have appeared since the baud rate on the switch in different than the one that you use on your CLI applicaiton ( PUTTY, SecureCRT etc. ) The default BAUD rate on a Cisco switch is 9600.


The gibberish characters can also appear after an IOS upgrade.


I hope this did help
