This lab focuses on QoS, including MQC, Rate-limit, Multicast Rate-limit, WFQ, and WRED.
Here are some things that I need to watch out for.
This task specifically says to configure GTS for Frame Relay. In order to configure GTS for FR, you need ACLs to classify traffic, and then under the interface use the "traffic-shape" command.
And to verify, see below.
Config:
R4#
R4#sh run | sec access-list
access-list 101 permit tcp any any eq telnet
access-list 101 permit tcp any eq telnet any
access-list 101 permit icmp any any
access-list 102 permit tcp any any eq ftp
access-list 102 permit tcp any eq ftp any
access-list 103 permit ip any any
alias exec sa sh access-list

Also, in order to configure Adaptive GTS
Config:
R5#
R5#sh run int s1/0.56

end
R5#
Task 13.7 - CAR
Remember, when a task says CAR, use the rate-limit command. Using ACLs to classify traffic and then combining it with the interface rate-limit command and the direction you can accomplish a single bucket policing.
Task 13.8 - Multicast Rate-limit
This tasks ask you to rate limit the incoming multicast traffic from a range of multicast groups,
226.0.0.1 to 226.0.0.126.
Config:
#sh run int f1/0

end
R1#sh run | sec access-list
