Configuring A Source Ip Address For The Igmp Messages Sent By The Proxy; Configuring An Igmp Snooping Policy; Configuring A Multicast Group Filter - HP 6125G Configuration Manual

Step
2. Enter VLAN view.
3. Enable IGMP snooping
proxying in the VLAN.
Configuring a source IP address for the IGMP messages sent by
the proxy
You can set the source IP addresses in the IGMP reports and leave messages that the IGMP snooping
proxy sends on behalf of its attached hosts.
To configure the source IP addresses for the IGMP messages that the IGMP snooping proxy sends on
behalf of its attached hosts in a VLAN:
Step
1. Enter system view.
2. Enter VLAN view.
3. Configure a source IP
address for the IGMP
reports that the proxy sends.
4. Configure a source IP
address for the IGMP leave
messages that the proxy
sends.

Configuring an IGMP snooping policy

Before you configure an IGMP snooping policy, complete the following tasks:
Enable IGMP snooping in the VLAN.
•
• Determine the ACL rule for multicast group filtering.
Determine the maximum number of multicast groups that a port can join.
•
Determine the 802.1p precedence for IGMP messages.
•

Configuring a multicast group filter

On an IGMP snooping–enabled switch, you can configure a multicast group filter to limit multicast
programs available to users.
In an application, when a user requests a multicast program, the user's host initiates an IGMP report.
After receiving this report message, the switch resolves the multicast group address in the report and
looks up the ACL. If a match is found to permit the port that received the report to join the multicast group,
the switch creates an IGMP snooping forwarding entry for the multicast group and adds the port to the
forwarding entry. Otherwise, the switch drops this report message, in which case, the multicast data for
the multicast group is not sent to this port, and the user cannot retrieve the program.
