Cisco Cisco IOS Software Release 12.4(15)T

© 2007 Cisco Systems, Inc. All rights reserved.

The Signed Tcl Scripts feature allows you to create a certificate to generate a digital signature and sign 
a Tool Command Language (Tcl) script with that digital signature. This feature also allows you to work 
with existing scripts and certificates. The digital signature is verified for authentication and then run with 
trusted access to the Tcl interpreter. If the script does not contain the digital signature, the script may run 
in a limited mode for untrusted scripts, or may not run at all.
