Configuring QoS 173

RED

Run the RED operation for the packets sent between 8:00 and 18:00 every day from IP address 1.0.0.1 to the port E3/0/8. RED operation is set so that the queue length that triggers random discarding ranges from 64 Kbytes to 128 Kbytes. The probability for random discarding is 20%.

The 20-Port 10/100/1000BASE-T and 20-Port 1000BASE-X-SFP I/O modules do not support this configuration.

To create this configuration:

1Define the time range 8:00 to 18:00.

Define the time range.

[SW7750]time-range 3com 8:00 to 18:00 daily

2Define traffic rules for the packets of IP address 1.0.0.1.

[SW7750]acl number 2000

[SW7750-acl-basic-2000]rule 0 permit ip source 1.0.0.1 0.0.0.0

Traffic Bandwidth

For the packets sent between 8:00 and 18:00 each day to the port E3/0/8, the minimum bandwidth for those of source IP address 1.0.0.1 is 20M, the maximum bandwidth is 60M, with bandwidth weight of 40. The minimum bandwidth for those of source IP address 2.0.0.1 is 20M; maximum bandwidth is 60M, with bandwidth weight of 60.
