Enabling Igmp Report Suppression; Setting The Maximum Number Of Multicast Groups On A Port; Enabling The Multicast Group Replacement Feature - HPE FlexNetwork 5130 EI Series Configuration Manual

To enable dropping unknown multicast data for a VLAN:
Step
1. Enter system view.
2. Enter VLAN view.
3. Enable dropping unknown
multicast data for the VLAN.

Enabling IGMP report suppression

This feature enables the switch to forward only the first IGMP report for a multicast group to its
directly connected Layer 3 device. Other reports for the same group in the same query interval are
discarded. This reduces the multicast traffic.
To enable IGMP report suppression:
Step
1. Enter system view.
2. Enter IGMP-snooping view.
3. Enable IGMP report
suppression.

Setting the maximum number of multicast groups on a port

You can set the maximum number of multicast groups on a port to regulate the port traffic.
When you set the maximum number of multicast groups on a port, follow these guidelines:
•
This configuration takes effect only on the multicast groups that a port joins dynamically.
•
If the number of multicast groups on a port exceeds the limit, the system removes all the
forwarding entries related to that port from the IGMP snooping forwarding table. The receiver
hosts attached to that port can join multicast groups again before the number of multicast
groups on the port reaches the limit.
To set the maximum number of multicast groups on a port:
Step
1. Enter system view.
2. Enter Layer 2 Ethernet
interface view or Layer 2
aggregate interface view.
3. Set the maximum number of
multicast groups on a port.

Enabling the multicast group replacement feature

This feature enables the switch to replace an existing multicast group with a newly joined multicast
group when the number of groups exceeds the upper limit. This feature is typically used in the
