This howto explain how to enable or disable multicast on network device

DEVICE ETH0 :

 
# ifconfig eth0
 eth0      Link encap:Ethernet  HWaddr 00:0C:34:FE:AB:6A  
 inet addr:10.0.0.100  Bcast:10.0.0.255  Mask:255.255.255.0
 inet6 addr: fe80::20c:29ff:fef1:ffea/64 Scope:Link
 UP BROADCAST RUNNING MULTICAST MTU:1500  Metric:1
 RX packets:5339836 errors:0 dropped:0 overruns:0 frame:0
 TX packets:5486444 errors:0 dropped:0 overruns:0 carrier:0
 collisions:0 txqueuelen:1000 
 RX bytes:820300389 (782.2 MiB)  TX bytes:1929979381 (1.7 GiB)
 Base address:0x1400 Memory:e8820000-e8840000

Disable Multicast: 

# ifconfig eth0 -multicast  
# ifconfig eth0
 eth0      Link encap:Ethernet  HWaddr 00:0C:34:FE:AB:6A   
 inet addr:10.0.0.100  Bcast:10.0.0.255  Mask:255.255.255.0
