Answers: Serial Config 1

Time to check your config for a back-to-back serial link in a lab. Check out the requirements back in the lab post, create your answers, and come back here to check your work.

Example 1: R1 Config

Example 2: R2 Config



Cisco serial interfaces use a default encapsulation of High-Level Data Link Control (HDLC); It is however also important to note that this is a Cisco proprietary version of HDLC. Most serial interfaces on Cisco devices support a number of different encapsulation types including the three most common: HDLC, Point-to-Point Protocol (PPP) and Frame-Relay. This lab asks for HDLC, so no configuration is necessary to set the type of data link protocol with the encapsulation command.

For a link in the lab, created with a back-to-back serial cable, the clock rate defines the speed at which the router acting as DCE clocks the link. At later IOS versions, IOS defaults to clock at 2Mbps. However, in this case, the lab asks for 512Kbps. The clock rate needs to be set only on the router acting as DCE, so only R1 should list a clock rate 512000 command, meaning 512,000 bps.
