I have been asked to troubleshoot an issue where information that is being copy and pasted to a new switch is getting garbled. This only happens if a lot of information is sent to the switch at once and it might only happen on a line or two. After a little digging into the switch I found that the switch by default is set to use 2 StopBits and not the default of 1. Please see below for my output of show terminal.
Line 0, Location: "", Type: ""
Length: 24 lines, Width: 80 columns
Baud rate (TX/RX) is 9600/9600, no parity, 2 stopbits, 8 databits
Status: PSI Enabled, Ready, Active, Ctrl-c Enabled, Automore On
Modem state: Ready
Special Chars: Escape Hold Stop Start Disconnect Activation
It is like this on two different switches I have looked at. I can't assume it is supposed to be like this. I assume it should be set at 1 when it comes direct from the factory.
Please see below for my version. Could this be a bug?

I am looking into if we have any agreements with Cisco so I can open up a TAC case. Not sure of that yet. I just wanted to see if anyone on here could point me in the right direction. Maybe i'm totally off but it just doesn't seem right that information gets garbled when copying and pasting to a switch. Esspecially when it is very inconsistent. Also note I am using the default Cisco settings when I connect to the switch and have tried with both Putty and Teraterm Pro.
I've not changed any of these and they are default. I wonder if you were to change the stopbit on yours to 1 if it would help your issue. As a side note, you may want to ensure that you don't have flow control set on your serial connection either. You'll also want to ensure that you have your baud rate set the same as the switch which is 9600.
The problem is there aren't our switches. We do batches of them for customers based on their configuration files. Some lines are getting left out as they get corrupted as they get pasted into the switch. I just assumed it was a terminal mismatch as I have seen weird things happen like this when it's entered too fast or when both sides don't match.
Can anyone else confirm their switches are also set to 2 stopbits. It it is truly the default I will move on and try to find another answer.
