Why is the switch not sending IGMP General Query when setting IGMP Snooping for a fixed VLAN?

Scenario

I'd like to set XGS3700 switch as the querier and to implement IGMP Snooping only in VLAN10.

Then I connected my PC in port 1 in VLAN 10, but somehow it didn't receive any IGMP General Query packet from the switch which is causing my multicast streams to age out.

Why is my PC under VLAN10 not receiving general queries?

Step

If we want to fix IGMP Snooping in a particular VLAN, there must be an interface IP for the VLAN to sned the Genernal query packets.

In this case, there is no interface IP configured for VLAN 10.

So we can set a static IP 192.168.10.1 for VLAN 10 in "Basic Setting -> IP Setup".

Verification

Since interface IP been set for VLAN 10, each end devices receive IGMP General Query with source 192.168.10.1 accordingly.
