2. Example of low-speed serial interface
Following example illustrates how to switch the low-speed serial interface from synchronous mode to
asynchronous mode:
interface serial 1/0
physical-layer mode async
Following example illustrates how to switch the low-speed serial interface from asynchronous mode to
synchronous mode, that is, the default mode:
interface serial 1/0
physical-layer mode sync
or
interface serial 1/0
no physical-layer mode
Following example is typical asynchronous serial interface configuration
interface serial 1/0
(Notice: if it is 16 asynchronous card , the value is inter async 0/0)
physical-layer mode async
ip address 192.168.1.1 255.255.255.0
encapsulation ppp
Following example is typical synchronous serial interface configuration
interface serial 1/0
physical-layer mode sync
ip address 192.168.1.2 255.255.255.0
no shutdown
