Setting up IGMP snooping on S3300's VLAN1

Hi,

The issue is like that the Guide is not entirely correct :)

For example: "Note: Query Mode is required only when working with multiple switches, but it can be safely enabled on a standalone switch." is not correct. You need a querier at all times, even if it is a standalone switch. Maybe you did not setup a querier?

Please try and follow these steps:

1. Enable IGMP snooping globally.
2. Enable IGMP snooping on the relevant VLAN (VLAN 1) under the "IGMP VLAN configuration".
3. Enable IGMP Querier globally.
4. Leave the global address at 0.0.0.0.
5. Set instead a Querier IP address per VLAN under the "Querier VLAN configuration". Set the "IP" to 1.1.1.1 for VLAN 1 (which you are using). The querier IP is only used for an election system, so 1.1.1.1 is fine here.
6. Make sure “Querier Election Participation Mode” is enabled in case you decide to add more switches.

Hope that helps :)
