 Example:

 Switch(config)#ip igmp snooping vlan 2 L2-general-query-source 192.168.1.2

1.2.10 ip igmp snooping vlan l2-general-querier-version

 Command: ip igmp snooping vlan <vlanid> L2-general-query-version <version>

 Function: Configure igmp snooping.

 Parameters: vlan-id is the id of the VLAN, limited to <1-4094>. version is the version

number, limited to <1-3>.

 Command Mode: Global mode.

 Default: version 3.

 Usage Guide: When the switch is connected to V1 and V2 capable environment, and for

VLAN which has source of layer 2 query configuration, the VLAN can be queried only if

the version number has been specified. This command is used to query the layer 2

version number.

 Example:

 Switch(config)#ip igmp snooping vlan 2 L2-general-query-version 2

1.2.11 ip igmp snooping vlan limit

 Command: ip igmp snooping vlan <vlan-id> limit {group <g_limit> | source

<s_limit>}

 no ip igmp snooping vlan <vlan-id> limit

 Function: Configure the max group count of VLAN and the max source count of every

group. The “no ip igmp snooping vlan <vlan-id> limit” command cancels this

configuration.

 Parameter: <vlan-id> is the VLAN number.

 g_limit：<1-65535>, max number of groups joined.

 s_limit：<1-65535>, max number of source entries in each group,

consisting of include source and exclude source.

 Command mode: Global Mode.

 Default: Maximum 50 groups by default, with each group capable with 40 source

entries.

 Usage Guide: When number of joined group reaches the limit, new group requesting

for

 joining in will be rejected for preventing hostile attacks. To use this command, IGMP

snooping must be enabled on VLAN. The “no” form of this command restores the

default other than set to “no limit”. For the safety considerations, this command will

not be configured to “no limit”. It is recommended to use default value and if layer 3

IGMP is in operation, please make this configuration in accordance with the IGMP

configuration as possible.

 Example: Switch(config)#ip igmp snooping vlan 2 limit group 300

1.2.12 ip igmp snooping vlan interface (ethernet | port-channel|) IFNAME limit
