streams. The MA5616 does not send the leave packets from the users before the last user to
the network side.
Step 4
Configure the IGMP version.
Run the
igmp version
{
v2
|
v3
} command to configure the IGMP version. By default, IGMP
V3 is enabled in the system. If the upper-layer and lower-layer devices on the network are of
the IGMP V2 version and cannot recognize the IGMP V3 packets, run this command to switch
the IGMP version.
IGMP V3 is compatible with IGMP V2 in packet processing. If IGMP V3 is enabled on the
MA5616 and the upper-layer multicast router switches to IGMP V2, the MA5616 automatically
switches to IGMP V2 when receiving the IGMP V2 packets. If the MA5616 does not receive
any IGMP V2 packets within the preset IGMP V2 time to live (TTL) time, it automatically
switches back to IGMP V3. In BTV mode, run the
igmp proxy router timeout
command to set
the IGMP V2 TTL time. By default, the TTL time is 400s.
Step 5
Change the priority for forwarding IGMP packets.
Run the
igmp priority
command to change the priority for forwarding the IGMP packets on the
uplink port. By default, the priority is 6 and it need not be changed.
l
In IGMP proxy mode, the IGMP packets sent to the network side adopt the priority set through
the
igmp priority
command in the multicast VLAN.
l
In IGMP snooping mode, the IGMP packets forwarded to the network side adopt the priority
of the user traffic stream. The priority of the traffic stream is set through the traffic profile.
Step 6
Check whether the configuration is correct.
l
Run the
display igmp config vlan
command to query the attributes of the multicast VLAN.
l
Run the
display igmp program vlan
command to query the information about the multicast
program in the multicast VLAN.

Example
Assume that the VLAN ID is 10, the program is configured statically, the IP address of the
program is 224.1.1.1, the program bandwidth is 5000 kbit/s, the multicast uplink port is 0/0/1,
the IGMP proxy is enabled, and the IGMP version is V3. To configure a program with these
attributes, do as follows:
huawei(config)#
vlan 10 smart
huawei(config)#
multicast-vlan 10
huawei(config-mvlan10)#
igmp match mode enable
This operation will delete all the programs in current multicast vlan
Are you sure to change current match mode? (y/n)[n]:
