Configuration Guide
bandwidth of the user (bandwidth configured for the user – total bandwidth of the online
programs of the user) with the bandwidth of the multicast program. The system determines
whether the user can watch the multicast program based on the result:
l
l
If the CAC function is not enabled, the system does not guarantee the bandwidth of the multicast
program. In this case, the picture quality of the requested program is poor. For example, mosaic
and delay occur.
Procedure
Step 1 In global config mode, run the btv command to enter BTV mode.
Step 2 Enable the CAC function globally.
l Run the igmp bandwidthCAC enable function to enable the CAC function globally.
l By default, the CAC function is enabled globally.
Step 3 Configure the bandwidth of the multicast program.
l Run the igmp program add command to configure the bandwidth of the multicast program.
l By default, the bandwidth of the multicast program is 5000 kbit/s.
Step 4 Configure the bandwidth of the multicast user.
l Run the igmp user add service-port index max-bandwidth command to configure the
l Before configuring the bandwidth of the multicast user, ensure that the service port of the
l By default, the bandwidth of the multicast user is not limited (no-limit).
Step 5 Check whether the multicast bandwidth is configured correctly.
l Run the display igmp config global command to check whether the CAC function is enabled
l Run the display igmp program command to query the bandwidth of the multicast program.
l Run the display igmp user command to query the bandwidth of the multicast user.

Example
Assume that the CAC function is enabled globally, the bandwidth of multicast user 0/1/0 is 10
Mbit/s, and the bandwidth of the multicast program with IP address 224.1.1.1 is 1 Mbit/s. To
perform the configurations, do as follows:
huawei(config)#btv
huawei(config-btv)#igmp bandwidthcAC enable
huawei(config-btv)#igmp user add service-port 0 max-bandwidth 10240 //0 is the
service port ID of the multicast user.
huawei(config-btv)#multicast-vlan 10
huawei(config-mvlan10)#igmp program add ip 224.1.1.1 bandwidth 1024
Issue 04 (2011-10-30)
If the remaining bandwidth of the user is sufficient, the system adds the user to the multicast
group.
If the bandwidth is insufficient, the system does not respond to the request of the user. That
is, the request of the user fails.
