Configuration Mode
You can configure the Ethernet or Token Ring interfaces on your 2-slot network module manually,
by entering Cisco IOS commands on the command line. This method, called configuration mode,
provides the greatest power and flexibility.
Before you begin, disconnect all WAN cables from the router to keep it from trying to run the
AutoInstall process. The router tries to run AutoInstall whenever you power it ON if there is a WAN
connection on both ends and the router does not have a valid configuration file stored in nonvolative
random-access memory (NVRAM) (for instance, when you add a new interface). It can take several
minutes for the router to determine that AutoInstall is not connected to a remote Transmission
Control Protocol/Internet Protocol (TCP/IP) host.
To enter configuration mode, follow this procedure:
