After you configure FR DLCI or
FR port mode encapsulation on a
serial interface, you must use the
reset fr inarp command to clear
FR dynamic address mappings
between the PE and the CE. For
more information about the reset
fr inarp command, see Layer
2—WAN Command Reference.
By default, the link layer protocol
of an interface is PPP.
Required for FR DLCI
encapsulation.
By default, no virtual circuit
exists.
Required for FR DLCI
encapsulation.
The DLCI number must be the
same as that configured on the
connected CE.
