15. EXAMPLE CISCO CONFIGURATION COMMANDS
15.1 The following commands are provided as an example to further illustrate the recom-
mended configuration with respect to security. Quality of Service (QoS) configuration is
beyond the scope of this appendix. These configuration examples are based on the Cisco
®
IOS
Firewall feature set. Adtran
®
routers use a very similar command set called AOS. See “Adtran
NetVanta Switch/Router Example” on page F-30 for more information on Adtran routers.
These commands are not intended to be complete; they are only a guideline.
