37.2.9 ip igmp snooping vlan l2-general-querier-source
Command:
ip igmp snooping vlan <vlanid> L2-general-query-source <A.B.C.D>
no ip igmp snooping vlan <vlanid> L2-general-query-source
Function:
Configure source address of query of igmp snooping
Parameters:
<vlanid>: the id of the VLAN, with limitation to <1-4094>. <A.B.C.D> is the source address of the query operation.
Command Mode:
Global mode.
Default:
0.0.0.0
Usage Guide:
It is not supported on Windows 2000/XP to query with the source address as 0.0.0.0. So the layer 2 query source
address configuration does not function. The client will stop sending requesting datagrams after one is sent. And
after a while, it can not receive multicast datagrams.
Example:
Switch(config)#ip igmp snooping vlan 2 L2-general-query-source 192.168.1.2
