Configuration
8-26
IGMPv2 immediate leave: Disabled
IGMP VLAN querier: Disable
8.2.16 Configuring IP Multicast Policy on Ports
8.2.16.1 Configuring Source Port Check
To enable source port check, execute the following commands in the global
configuration mode:
Command Function
DES-7200(config)# ip igmp snooping
source-check port
Enable source port check.
DES-7200(config)# no ip igmp snooping
source-check port
Disable source port check.
The following example enables the IGMP Snooping source port check function:
DES-7200# configure terminal
DES-7200(config)# ip igmp snooping source-check port
DES-7200(config)# end
8.2.16.2 Configuring Source IP Check
There are two configuration commands for the source IP check: one command is
for the configuration of default source IP addresses of the legal multicast flows in
all multicast groups; and the other command is for the configuration of the default
source IP address for the legal multicast flows in the specified VLAN group. Only
with the default source IP check enabled in all groups, the source IP address of
the legal multicast server in a specific group can be set.
To enable source IP check, execute the following commands in the global
configuration mode:
Command Function
DES-7200(config)# ip igmp snooping
source-check default-server address
Enable source IP check and configure
the default source IP address of the
legal multicast flows in all multicast
groups. By default, this function is
disabled.
DES-7200(config)# no ip igmp
snooping source-check default-server
Disable source IP check.
DES-7200(config)# ip igmp snooping
limit-ipmc vlan vid address address
server address
Add the source IP address of the
legal multicast flow to a specified
multicast group addresses. By
default, the source IP address of
the legal multicast flow is the IP
address of the default-server.
DES-7200(config)# no ip igmp
snooping limit-ipmc vlan vid address
address
Cancel a limit-ipmc configuration.
The following example enables source IP check and set the default source IP
address to 1.1.1.1. In the example, a multicast group address-source IP address
entry is added, where vid is 1, group IP address is 233.3.3.3 and source ip
address is 1.1.1.2.
DES-7200# configure Terminal
DES-7200(config)# ip igmp snooping source-check default-server 1.1.1.1
DES-7200(config)# ip igmp snooping limit-ipmc vlan 1 address 223.3.3.3 server
1.1.1.2
