If You Need More Information
Your router and the Cisco IOS software running on it contain extensive features and functionality,
which are documented in the following resources:
• Cisco Documentation CD-ROM package
Cisco documentation and additional literature are available in a CD-ROM package, which ships
with your product. The Documentation CD-ROM, a member of the Cisco Connection Family, is
updated monthly; therefore, it might be more up to date than printed documentation. To order
additional copies of the Documentation CD-ROM, contact your local sales representative or call
customer service. The CD-ROM package is available as a single package or as an annual
subscription.
