Configuration procedure

1. Configure Router A:

# Configure GTS on GigabitEthernet 1/0/3, shaping the packets when the sending rate exceeds

500 kbps to decrease the packet loss rate of GigabitEthernet 1/0/1 of Router B.

<RouterA> system-view

[RouterA] interface gigabitethernet 1/0/3

[RouterA-GigabitEthernet1/0/3] qos gts any cir 500

[RouterA-GigabitEthernet1/0/3] quit

# Configure ACLs to permit the packets from Server and Host A.

[RouterA] acl number 2001

[RouterA-acl-basic-2001] rule permit source 1.1.1.1 0

[RouterA-acl-basic-2001] quit

[RouterA] acl number 2002

[RouterA-acl-basic-2002] rule permit source 1.1.1.2 0

[RouterA-acl-basic-2002] quit

# Configure CAR policies for different flows received on GigabitEthernet 1/0/1.

[RouterA] interface gigabitethernet 1/0/1

[RouterA-GigabitEthernet1/0/1] qos car inbound acl 2001 cir 54 cbs 4000 ebs 0 green

pass red remark-prec-pass 0

[RouterA-GigabitEthernet1/0/1] qos car inbound acl 2002 cir 8 cbs 1875 ebs 0 green

pass red discard

[RouterA-GigabitEthernet1/0/1] quit

2. Configure Router B:

# Configure a CAR policy on GigabitEthernet 1/0/1 to limit the incoming traffic rate to 500 kbps

and drop the excess packets.

<RouterB> system-view

[RouterB] interface gigabitethernet 1/0/1

[RouterB-GigabitEthernet1/0/1] qos car inbound any cir 500 cbs 32000 ebs 0 green pass

red discard

[RouterB-GigabitEthernet1/0/1] quit
