Configuration Management
Cisco SDM allows you to edit the router configuration file and to reset the router
configuration to factory defaults. Because editing the configuration file directly
and resetting the router to factory defaults can cause yo u to lose the connection
between the PC and the router, be sure to read the online help for all screens in
this area of Cisco SDM.
Manually Editing the Configuration File
Cisco SDM allows you to edit the router configuration file by providing a
configuration editor that you can use to import a configuration file or use to enter
Cisco IOS CLI commands directly.
Cisco SDM supports the most widely-used Cisco IOS commands and keywords,
but it cannot support every CLI command. If you are experienced with the Cisco
IOS CLI and have an excellent understanding of how the configuration commands
that you want to enter will affect the behavior of the router and the network in
which it resides, you may find that using the configuration editor is faster than
using Cisco SDM dialogs. If you want to add a configuration that Cisco SDM does
not support, you must either use the Config Editor to do so, or open a Telnet
session with the router and use the Cisco IOS CLI.
Using the Config Editor bypasses Cisco SDM validation. Although Cisco SDM
returns IOS error messages, it cannot compare your configuration changes against
the running configuration and inform you of conflicts thay m ay result. For
example, if you use Cisco SDM dialogs to enter a VPN configuration on a router
that already has a firewall configuration, Cisco SDM examines the firewall and
determines which permit statements must be added to enable VPN traffic to pass
