Autodetect
Click Autodetec t to have SDM discover the encapsulation type. If SDM succeeds,
it will automatically supply the encapsulation type and other configuration
parameters it discovers.
Note SDM supports autodetect on SB106, SB107, Cisco 836 and Cisco 837 routers.
However if you are configuring a Cisco 837 router and the router is running an
IOS image of version 12.3(8)T or version 12.3(8.3)T, the autodetect feature is not
supported.
