IGMP Snooping Commands

23-1 ip igmp snooping

This command is used to enable the IGMP Snooping state. Use the no form of this command to disable the IGMP

Snooping state.

ip igmp snooping no ip igmp snooping

Parameters

Default

Command Mode

None.

Disabled on global switch and each VLAN interface.

Global Configuration Mode and Interface Configuration Mode.

Command Default Level

Level: 8

Usage Guideline

In the global configuration mode, you can enable or disable the IGMP Snooping global state, and in the interface configuration mode, you can enable or disable the

IGMP Snooping interface state.

For a VLAN to operate with IGMP Snooping, both the global state and per interface state must be enabled.

You can verify your configuration through command show ip igmp snooping.

Example

This example shows how to enable the IGMP Snooping global state.

DXS-3600-32S#configure terminal

DXS-3600-32S(config)#ip igmp snooping

DXS-3600-32S(config)#

Example

This example shows how to disable the IGMP Snooping state on interface VLAN 1.


DXS-3600-32S(config)#vlan 1

DXS-3600-32S(config-vlan)#no ip igmp snooping

DXS-3600-32S(config-vlan)#

23-2 ip igmp snooping fast-leave

This command is used to enable IGMP Snooping fast leave function. Use the no form of this command to disable this function.

ip igmp snooping fast-leave no ip igmp snooping fast-leave

Parameters

Default

None.

By default, this option is disabled.

Command Mode

Interface Configuration Mode.


Level: 8

Usage Guideline

IGMP Snooping fast-leave processing allows removing a member interface from the membership entry without sending out IGMP group-specific queries, so that make the leaving more quickly. Upon receiving a group-specific IGMPv2 leave message or

IGMPv3 TO_INCLUDE(NULL), if the host is the last member of group on the interface, IGMP Snooping immediately removes the interface from the membership table entry for that multicast group.

To verify your configuration, use show ip igmp snooping.

Global Configuration Mode.


Level: 8

Usage Guideline

When you enable IGMP Snooping, the switch will consider an interface connected to a multicast router when receiving multicast packets which are PIM control messages, DVMRP control messages or IGMP query messages with non-zero source IP on that interface. This command is used to configure the aging out time of these dynamically learned router interfaces.

To verify your configuration, use command show ip igmp snooping.

Example

ip igmp snooping static-group GROUP-ADDRESS {interface INTERFACE-TYPE INTERFACE-ID [, | -] | group-

channel GROUP-ID}

no ip igmp snooping static-group GROUP-ADDRESS {interface INTERFACE-TYPE INTERFACE-ID [, | -] |

group-channel GROUP-ID}

Parameters

GROUP-ADDRESS

,

INTERFACE-TYPE

INTERFACE-ID

-

GROUP-ID

Specifies the address of the multicast group. This is a multicast IP address in fourpart dotted-decimal notation.

Specifies the interface type. The only possible valid value is tenGigabitEthernet.

Specifies the port number.

Specifies a series of ports, or separate a range of ports from a previous range. No space before and after the comma.

Specifies a range of ports. No space before and after the hyphen.

Specifies the port-channel number.

Default

Command Mode

No any static group is configured.



Level: 8

241

Usage Guideline


This command allows users to create an IGMP Snooping static group and add static members to this group. A member interface configured in a static group will be processed as the IGMP Snooping ever receiving IGMP group subscribing message on it. Any traffic destined to the static group in the VLAN will be forwarded to all dynamic learned and static configured member ports. Only one difference from dynamic group member, a static group member won’t be aged out, and it can only be manually removed.

To verify you configuration, use command show ip igmp snooping static-group.

Example

This example shows how to configure interface 2-4 to be static member interfaces for group 235.0.0.0 in VLAN 1.



DXS-3600-32S(config-vlan)#ip igmp snooping static-group 235.0.0.0 interface tenGigabitEthernet

2-4


Example

This example shows how to delete interface 2 from group 235.0.0.0 in VLAN 1.

23-7 ip igmp snooping max-response-time

This command is used to configure the max response time in IGMP Snooping. To restore the default value, use the no form of this command.

ip igmp snooping max-response-time SECONDS

no ip igmp snooping max-response-time

Parameters

SECONDS

Specifies the maximum time in seconds of waiting for reports from members. The range is 1 to 25 seconds.

Default

10 seconds.

Command Mode



Level: 8

Usage Guideline

The max response time is used to calculate the Max Resp Code inserted into the periodic general queries. By varying the time, an administrator may tune the burstiness of IGMP messages on the network; larger values make the traffic less bursty, as host responses are spread out over a larger interval. The number of seconds represented by the max response time must be less than the Query

Interval.

To verify your configuration, you can use show ip igmp snooping.

Example

This example shows how to configure IGMP Snooping querier max response time to be 11 seconds on VLAN 1.



DXS-3600-32S(config-vlan)#ip igmp snooping max-response-time 11


242


Example

This example shows how to restore the default value of IGMP Snooping max response time on VLAN 1.



DXS-3600-32S(config-vlan)#no ip igmp snooping max-response-time


23-8 ip igmp snooping query-interval

This command is used to configure the interval between general queries sent by IGMP Snooping querier. To restore the default value, use the no form of this command.

ip igmp snooping query-interval SECONDS

no ip igmp snooping query-interval

Parameters

SECONDS

Specifies the amount of time in seconds between general query transmissions. The range is 1 to 31744 seconds.

Default

Command Mode

125 seconds.



Level: 8

Usage Guideline

The query interval is the interval between General Queries sent by the Querier. By varying the query interval, an administrator may tune the number of IGMP messages on the network; larger values cause IGMP Queries to be sent less often.


Example

This example shows how to configure the IGMP Snooping query interval to be 60 seconds on VLAN 1.



DXS-3600-32S(config-vlan)#ip igmp snooping query-interval 60


Example

This example shows how to restore the default value of IGMP Snooping query interval on VLAN 1.



DXS-3600-32S(config-vlan)#no ip igmp snooping query-interval


23-9 ip igmp snooping version

This command is used to configure the IGMP version in IGMP Snooping. To restore the default version, use the no form of this command.

ip igmp snooping version {1 | 2 | 3} no ip igmp snooping version

Parameters

{1 | 2 | 3}

Specifies the three version numbers, ranging 1 to 3.

243


Default

Command Mode

By default, this value is 3.



Level: 8

Usage Guideline

IGMP Snooping can be configured to one of the three versions: v1, v2 and v3. When it is configured to v1, it means the IGMP Snooping will run in v1 compatibility mode.

When it is configured to v2, it means the IGMP Snooping will run in v2 compatibility mode. Version 3 is just the IGMP Snooping running version.

In spite of the version configured on the switch, IGMP Snooping will process

IGMPv1/v2/v3 report/leave packet as defined in RFC 3376 (IGMPv3). The difference behaves in different version is the IGMP general query transmitting and the querier electing when the querier state is enabled.

General Query Transmit:

• When configured to version 1, IGMP Snooping will only send IGMPv1 general query packet.



Querier Elect:

• When configured to version 1, IGMP Snooping will always act as querier, and will not initiate a new Querier electing no matter what the IGMP query packet it received.

• When configured to version 2 or version 3, IGMP Snooping will initiate a new querier electing if any IGMP v2 or v3 query packet is received. When receiving an IGMP v1 Query packet, IGMP Snooping won’t initiate a new querier electing.


Example

This example shows how to configure the IGMP Snooping version to be 2 on VLAN

1.



DXS-3600-32S(config-vlan)#ip igmp snooping version 2


Example

This example shows how to restore the default version on VLAN 1.



DXS-3600-32S(config-vlan)#no ip igmp snooping version
