7. Configure an IP address for VLAN 100. This address will be used as the IGMP snooping querier address if
this switch becomes the querier.
(QCT) #configure
(QCT) (Config)#interface vlan 100
(QCT) (if-vlan100)#ip address 192.168.10.2 255.255.255.0
(QCT) (if-vlan100)#exit
8. Specify the address to use as the source address for IGMP queries sent from any interface. The global
querier address is the IP address of VLAN 100.
(QCT) (Config)#ip igmp snooping querier address 192.168.10.2
9. Enable IGMP snooping on ports 1–3.
(QCT) (Config)#interface range 0/1-0/3
(QCT) (Interface 0/1-0/3)#ip igmp snooping interfacemode
10. Configure ports 1–3 as members of VLAN 100.
(QCT) (Interface 0/1-0/3)#switchport allowed vlan add 100
(QCT) (Interface 0/1-0/3)#exit
11. Enable IGMP on port 24, and configure the port as a trunk port that connects to the data center switch.
(QCT) (Config)#interface 0/24
(QCT) (Interface 0/24)#ip igmp snooping interfacemode
(QCT) (Interface 0/24)#switchport allowed vlan add tagged 100
(QCT) (Interface 0/24)#exit
(QCT) (Config)#exit
