T101 Encapsulation Option

From DocWiki

Jump to: navigation, search

T-101 encapsulation option is not available under interface configuration mode. How to configure T-101?

Configure the physical-layer async command and change the mode of the interface to async mode. If the interface is not in async mode, then enter the show line number command to confirm that the line is invalid. See the example given below for more information:
