Configuring a Serial Interface with PPP Encapsulation: Example
The following example shows how to create and configure a serial interface with PPP encapsulation:
RP/0/0RP0RSP0/CPU0:router# configure
RP/0/0RP0RSP0/CPU0:router(config)# interface serial 0/3/0/0/0:0
RP/0/0RP0RSP0/CPU0:router(config-if)# ipv4 address 172.18.189.38 255.255.255.224
RP/0/0RP0RSP0/CPU0:router(config-if)# encapsulation ppp
RP/0/0RP0RSP0/CPU0:router(config-if)# no shutdown
RP/0/0RP0RSP0/CPU0:router(config-if)# ppp authentication chap MIS-access
RP/0/0RP0RSP0/CPU0:router(config-if)# end
Uncommitted changes found, commit them? [yes]: yes
The following example shows how to configure serial interface 0/3/0/0/0:0 to allow two additional retries
after an initial authentication failure (for a total of three failed authentication attempts):
RP/0/0RP0RSP0/CPU0:router# configuration
RP/0/0RP0RSP0/CPU0:router(config)# interface serial 0/3/0/0/0:0
RP/0/0RP0RSP0/CPU0:router(config-if)# encapsulation ppp
RP/0/0RP0RSP0/CPU0:router(config-if)# ppp authentication chap
RP/0/0RP0RSP0/CPU0:router(config-if)# ppp max-bad-auth 3
RP/0/0RP0RSP0/CPU0:router(config-if)# end
Uncommitted changes found, commit them? [yes]: yes
