Example Cisco Configuration Commands
The following commands are provided as an example to further illustrate the recommended
configuration with respect to security. 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. For more information about Adtran routers Adtran Netvanta
Switch/Router on page 1-452 . These commands are not intended to be complete; they are only a
guideline.
