5.4 Static Multicast Configuration
5.4.1 Brief introduction of Static Multicast
Static multicast configuration command is used to crewate multicast group and add interfaces
to it. If the switch supports multicast, when receiving multicast packet, detect whether there is
multicast group. If it doesn’t exist, transfer the multicast packet as broadcast packet. If it exists,
transfer the multicast packet to all interface members of this multicast group.
5.4.2 Static Multicast Configuration
Static Multicast Configuration list
Configure static multicast in following turns:
Create multicast group
Add interfaces to multicast group
Display multicast group information
Delete interface members from multicast group
Delete multicast group
Create multicast group
Use following command in global configuration mode to create a multicast group:
multicast mac-address mac vlan vlan-id
mac: The mac address of multicast group displayed in the form of multicast address, such as:
01:00:5e:**:**:**.vlan-id ranges from 1 to 4094. If the VLAN doesn’t exist, the multicast group
adding fails.
Example:
! Create a multicast group to VLAN 1 with the mac address being 01:00:5e:01:02:03
QTECH(config)#multicast mac-address 01:00:5e:01:02:03 vlan 1
Add interfaces to multicast group
Use multicast mac-address vlan interface command in global configuration mode to add
interface to existed multicast group:
multicast mac-address mac vlan vlan-id interface { all | interface-list }
mac: Means mac address of existed multicast which is in the form of multicast mac-address,
such as: 01:00:5e:**:**:**. Vlan-id ranges from 1 to 4094. Multicast group is assembled by
vlan-id and mac-address. Interface-list is optional. If all is chosen, all interfaces in system in
multicast mac-address vlan interface command. If the VLAN doesn’t exist, the multicast group
adding fails.
For example:
! Add interface Ethernet 0/2 to ethernet 0/4 ethernet 0/8 to existed multicast group
QTECH(config)#multicast mac-address 01:00:5e:01:02:03 vlan 1 interface ethernet 0/2 to
ethernet 0/4 ethernet 0/8
Display multicast group information
Use show multicast command to display the information of the specified or all existed multicast
group which includes multicast group interface information, IGMP interface list information:
show multicast [ mac-address mac ]
Mac is the mac address existed in multicast group. If mac-address is not specified, input show
multicast command, information of the entire multicast group is displayed.
For example:
! Display the information of multicast group with the MAC address to be 01:00:5e:01:02:03
QTECH(config)#show multicast mac-address 01:00:5e:01:02:03
