IGMP Snooping

– 462 –

Command Mode

Global Configuration

Command Usage

◆

When proxy reporting is enabled with this command, the switch performs
“IGMP Snooping with Proxy Reporting” (as defined in DSL Forum TR-101, April
2006), including last leave, and query suppression. Last leave sends out a proxy
query when the last member leaves a multicast group, and query suppression
means that specific queries are not forwarded from an upstream multicast
router to hosts downstream from this device.

◆

If the IGMP proxy reporting is configured on a VLAN, this setting takes
precedence over the global configuration.

Example

Console(config)#ip igmp snooping proxy-reporting

Console(config)#

ip igmp snooping

querier

This command enables the switch as an IGMP querier. Use the

no

form to disable it.

Syntax

[

no

]

ip igmp snooping querier

Default Setting

Disabled

Command Mode

Global Configuration

◆

If enabled, the switch will serve as querier if elected. The querier is responsible
for asking hosts if they want to receive multicast traffic.

Example

Console(config)#ip igmp snooping querier

Console(config)#

ip igmp snooping

router-alert-

option-check

This command discards any IGMPv2/v3 packets that do not include the Router
Alert option. Use the

no

form to ignore the Router Alert Option when receiving

IGMP messages.

Syntax

[

no

]

ip igmp snooping router-alert-option-check
