Configuring Source Ip Address Of Igmp Queries - HP A5500 SI Switch Series Configuration Manual

To do...
Enter IGMP snooping view
Set the maximum response time
for IGMP general queries
Set the IGMP last-member query
interval
Configuring IGMP queries and responses in a VLAN
Follow these steps to configure IGMP queries and responses in a VLAN:
To do...
Enter system view
Enter VLAN view
Set the IGMP general query
interval
Set the maximum response time
for IGMP general queries
Set the IGMP last-member query
interval
CAUTION:
In the configuration, make sure that the IGMP general query interval is larger than the maximum
response time for IGMP general queries. Otherwise, multicast group members might be deleted by
mistake.

Configuring source IP address of IGMP queries

After the switch receives an IGMP query whose source IP address is 0.0.0.0 on a port, it does not enlist
that port as a dynamic router port. This might prevent multicast forwarding entries from being correctly
created at the data link layer and eventually cause multicast traffic forwarding to fail. To avoid this
problem, when a Layer 2 switch acts as the IGMP snooping querier, HP recommends you to configure a
non-all-zero IP address as the source IP address of IGMP queries.
Follow these steps to configure source IP address of IGMP queries:
To do...
Enter system view
Enter VLAN view
Configure the source address of
IGMP general queries
Configure the source IP address of
IGMP group-specific queries
Use the command...
igmp-snooping
max-response-time interval
last-member-query-interval interval
Use the command...
system-view
vlan vlan-id
igmp-snooping query-interval interval
igmp-snooping max-response-time
interval
igmp-snooping last-member-query-
interval interval
Use the command...
system-view
vlan vlan-id
igmp-snooping general-query source-ip { ip-
address | current-interface }
igmp-snooping special-query source-ip { ip-
address | current-interface }
