Context
To enable hosts on the network to which the interface is connected to join the specified multicast
groups and to receive messages from the groups, you need to set an ACL rule on the related
interface to filter the received messages. In this case, the range of groups that the interface serves
can be limited.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface interface-type interface-number
The interface view is displayed.
The S7700 uses this interface to communicate with hosts. On the S7700, VLANIF interfaces
and loopback interfaces support IGMP.
Step 3 Run:
igmp group-policy { acl-number | acl-name acl-name } [ 1 | 2 | 3 ]
The range of multicast groups that the interface can join is configured.
By default, an interface can join any multicast group.

4.3.7 Checking the Configuration
Prerequisite
The configuration of basic IGMP functions is complete.
Procedure
l Run the display igmp interface [ interface-type interface-number ] [ verbose ] command
to check the configuration and running status of IGMP on an interface.
l Run the display igmp group [ group-address | interface interface-type interface-
number ]
*
static command to check the information about the members of the static IGMP
multicast group.
l Run the display igmp group[ group-address | interface interface-type interface-
number ]
*
[ verbose ] command to check the information about the members that
dynamically join the IGMP multicast group.
----End
Example
Run the display igmp interface vlanif 3 command to check the configuration of IGMP on
VLANIF 3.
<Quidway> display igmp interface vlanif 3
