Configuring the source IP address for IGMP messages in a VSI
Step
1.
Enter system view.
2.
Enter VSI view.
3.
Configure the source IP
address for IGMP general
queries.
4.
Configure the source IP
address for IGMP
group-specific queries.
5.
Configure the source IP
address for IGMP reports.
6.
Configure the source IP
address for IGMP leave
messages.
Setting the 802.1p priority for IGMP messages
When congestion occurs on outgoing ports of the Layer 2 device, it forwards IGMP messages in their
802.1p priority order, from highest to lowest. You can assign a higher 802.1p priority to IGMP
messages that are created or forwarded by the device.
You can set the 802.1p priority globally for all VLANs and VSIs in IGMP-snooping view or for a VLAN
in VLAN view. For a VLAN, the VLAN-specific configuration takes priority over the global
configuration.
Setting the 802.1p priority for IGMP messages globally
Step
1.
Enter system view.
2.
Enter IGMP-snooping view.
3.
Set the 802.1p priority for
IGMP messages.

By default, the source IP address of
IGMP general queries is the IP
address of the gateway interface for a
VSI. If the gateway interface does not
have an IP address, the source IP
address is 0.0.0.0.
By default, the source IP address of
IGMP group-specific queries is one of
the following:
•
The source IP address of IGMP
general queries if the IGMP
snooping querier of a VSI has
received IGMP general queries.
•
The IP address of the gateway
interface for the VSI if the IGMP
snooping querier does not
receive an IGMP general query.
•
0.0.0.0 if the gateway interface of
the VSI does not have an IP
address.
By default, the source IP address of
IGMP reports is the IP address of the
gateway interface for a VSI. If the
gateway interface does not have an IP
address, the source IP address is
0.0.0.0.
By default, the source IP address of
IGMP leave messages is the IP
address of the gateway interface for a
VSI. If the gateway interface does not
have an IP address, the source IP
address is 0.0.0.0.
