You have connected an endstation to the Switch on a certain
VLAN, and although the Switch is a member of that VLAN and you
can see (via the LED) that the port is sending traffic, the
endstation acts as though it is not receiving the traffic.
The port may have been configured in the correct VLAN, but if the port
is a tagged member and the endstation does not support tagged VLANs
then the endstation will ignore the tagged traffic.
To ensure that traffic is passed across the VLAN from the Switch to the
endstation, configure the Switch port as an untagged member of the
relevant VLAN.
Your Switch should be operating as an IGMP Querier, but it is not
sending query packets to the network.
Check that:
The Switch does not have the IP address 0.0.0.0. If it does,
change the IP address, and re-enable IGMP Multicast Learning.
The network is only using the management VLAN. The Switch can
only act as the querier in the management VLAN.
