PPP encapsulation over HDLC [7:25912]

2001-11-12 Thread BASSOLE Rock

Hello group,


I have a configuration on a router that does "ppp encapsulation" over a
serial line. Our operator is running HDLC on the line. On this line we get
some CRC errors from time to time. Can this configuration be responsible for
the CRC errors?

Is it correct to run "ppp encapsulation" over hdlc lines?

Thank you group

Rock -

On a serial line, one generally runs either PPP, hdlc, or frame -- but 
only one! If the command "encapsulation ppp" is used, then that is your 
encapsulation type, not hdlc. The source of your errors is elsewhere.

A good starting point is to read up on troublshooting serial line problems


you can do that at

The article at this link suggests that you only worry if errors are more 
than about 1% of the traffic passed.
