Configuring a multicast group filter
To prevent the hosts attached to an interface from joining certain multicast groups, you can specify
an ACL on the interface as a packet filter. As a result, the receive hosts attached to this interface can
join only the multicast groups that the ACL permits.
To configure a multicast group filter:

3.
Configure a multicast group
filter.
igmp group-policy
acl-number
[
version-number
]
By default, no multicast group
filter is configured on this
interface. Namely, hosts on the
current interface can join any valid
multicast group.
Setting the maximum number of multicast groups that an
interface can join
To configure the maximum number of multicast groups an interface can join:

3.
Configure the maximum
number of multicast groups
that the interface can join.
igmp group-limit
limit
By default, the upper limit is 4000 for the
HPE 5800 switches, and 2000 for the
HPE 5820X switches.
NOTE:
This configuration only limits the number of multicast groups that the interface dynamically joins.
Adjusting IGMP performance
This section describes how to adjust IGMP performance.
Configuration prerequisites
Before adjusting IGMP performance, complete the following tasks:
•
Configure any unicast routing protocol so that all devices in the domain are interoperable at the
network layer.
•
Configure basic IGMP functions.
