Hello experts,

While I am passing password like **$abc** i was getting error on cli due to $ symbol in front of the text  
Can anyone please share your idea on that.

leaf password\_val {  
description “Password. Use of % character must be escaped with (Max Size -127)”;  
type tailf:aes-cfb-128-encrypted-string {  
length “1…200”;  
}  
}

Thanks

You can enter any cleartext value either directly or in the form `$0$cleartext`, so for example `$0$$abc`. The prefix `$0$` indicates cleartext; when you read such value, you get something like `$8$longencryptedpassword`. That’s why you could not enter a value starting with `$`, this character has a special meaning at the beginning of the string.

Read the documentation for the type - it refers to the type `des3-cbc-encrypted-string` where this prefixing is explained in more detail.
