Catalyst 9300 as querier for IGMPv2

[AndreasKvist]

Dear all, 

Can the Catalyst 9300 act as a querier for IGMPv2?

I´ve found a a lot of documentation reagarding IGMP snooping and not so much on querier for IGMPv2.

Hi
the command is in software not the hardware its available in all IOS-XE software

y default, the IGMP snooping querier is configured to detect devices that use IGMP Version 2 (IGMPv2), but does not detect clients that are using IGMP Version 1 (IGMPv1). You can manually configure the max-response-time value when devices use IGMPv2. You cannot configure the max-response-time when devices use IGMPv1. (The value cannot be configured, and is set to zero).

Non-RFC-compliant devices running IGMPv1 might reject IGMP general query messages that have a non-zero value as the max-response-time value. If you want the devices to accept the IGMP general query messages, configure the IGMP snooping querier to run IGMPv1.

VLAN IDs 1002―1005 are reserved for Token Ring and FDDI VLANs, and cannot be used in IGMP snooping.
Examples

The following example shows how to globally enable the IGMP snooping querier feature:

Device(config)# ip igmp snooping querier

The following example shows how to set the IGMP snooping querier maximum response time to 25 seconds:

Device(config)# ip igmp snooping querier max-response-time 25
