Practical Exercise 8-1 Solution
Examples 8-31 through 8-35 show the PPPoA configurations for the DSL CPEs, Cisco 6160 DSLAM, and Cisco 6400.
Example 8-31 Configuration Output for lab-827A

In Example 8-33, two DSL profiles, premium and standard, are defined. As you can see, each of them is configured with different downstream and upstream speeds.

Example 8-36 shows that lab-827A has successfully passed the PPP negotiation and authentication. An IP address is assigned to the DSL connection.
Example 8-36 Output of show ip interface brief for lab-827A

Example 8-37 shows that lab-827B has successfully passed the PPP negotiation and authentication. An IP address is assigned to the DSL connection.
Example 8-37 Output of show ip interface brief for lab-827B

In Example 8-38, two virtual interfaces are cloned from the virtual template. They are served as Layer 3 termination for the DSL CPEs—lab-827A and lab-827B. Examples 8-39 and 8-40 show the details of two virtual interfaces.

Example 8-41 displays the DSL profile status for the default profile, premium profile, and standard profile. Keep in mind that the premium and standard profiles are created in this exercise. You can use show dsl profile [profile-name] to display a specific profile, all ports to which the profile is currently attached, and those port settings.
