Set WRED parameters and drop algorithm for packets at the port GE7/1/1: 
Configure parameters for WRED 0; outbound queue ID is 7; green-min-threshold 
is 150;  green-max-threshold is 500; green-max-prob is 5; yellow-min-threshold is 
100;  yellow-max-threshold is 150; yellow-max-prob is 10; red-min-threshold is 50; 
red-max-threshold is 100; red-max-prob is 15; exponent is 10; the port is in WRED 
drop mode; import the parameters of WRED 0.

Suppose the IP address of PC1 is 1.0.0.1 and that of PC2 is 2.0.0.1. The switch is 
uplinked through the port GE7/1/8. Count the packets sent from the switch to 
PC1 during the time range from 8:00 to 18:00 every day.
