Enabling The Multicast Group Replacement Feature; Displaying And Maintaining Igmp Snooping - HP MSR1002-4 Configuration Manual

Step
1. Enter system view.
2. Enter
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 device to replace an existing group with a newly joined group when the
number of groups exceeds the upper limit. This feature is typically used in the channel switching
application. Without this feature, the device discards IGMP reports for new groups, and the user
cannot change to the new channel.
Configuration restrictions and guidelines
When you enable the multicast group replacement feature, follow these restrictions and guidelines:
•
This configuration takes effect only on the multicast groups that a port joins dynamically.
•
You can enable this feature globally for all ports in IGMP-snooping view or for a port in interface
view. For a port, the port-specific configuration takes priority over the global configuration.
Configuration procedure
To enable the multicast group replacement feature globally:
Step
1. Enter system view.
2. Enter IGMP-snooping view.
3. Enable the multicast group
replacement
globally.
To enable the multicast group replacement feature on a port:
Step
