Chapter 23 Configuring Gigabit EtherChannel Features
Configuring VLAN-Based Load Balancing
encapsulation dot1q 1 primary gigabitethernet2/1/0 secondary gigabitethernet8/0/0
Configuration Example for Using the VLAN Group Feature to Apply QoS
Assume that the following configurations need to be performed on a port channel bundle
• Police ingress traffic for VLAN 2 at 100 mbps
• Police ingress traffic for VLAN 3 at 150 mbps
• Shape egress traffic for VLAN 3 at 50 mbps
• Shape egress traffic for VLAN 2 & 4 together at 150 mbps
Step 1 Create a port-channel bundle as follows:
interface port-channel 1
load-balancing vlan
no sh
Step 2 Create VLAN subinterfaces as follows:
interface port-channel 1.1
encapsulation dot1q 2 primary gig2/0/0 secondary gig3/0/0
ip add 3.0.0.1 255.255.255.0
no sh
interface port-channel 1.2
encapsulation dot1q 3 primary gig2/0/0 secondary gig3/0/0
ip add 3.1.0.1 255.255.255.0
no sh
interface port-channel 1.3
encapsulation dot1q 4 primary gig2/0/0 secondary gig3/0/0
ip add 3.2.0.1 255.255.255.0
no sh
Step 3 Create match-any vlan class-maps as follows:
Class-map match-any vlan_2
Match vlan 2
Class-map match-any vlan_3
Match vlan 3
Class-map match-any vlan_4
Match vlan 4
Class-map match-any vlan_2_4
Match vlan 2 4
Step 4 Create policy-maps as follows:
Policy-map mega_ingress
Class vlan_2
Police 100 mbps
Class vlan_3
Police 150 mbps
Policy-map mega_egress
Class vlan_3
Shape 50 mpbs
Class vlan_2_4
Shape 150 mbps
