In section 15, page 336, The 2.3.X Administration guide indicates that the unit will forward multicast packets on a downstream interface only if the device is the multicast querier for that interface. However, the device will not allow a downstream interface to be a querier.   I have two VLANs, VLAN1 and VLAN2. In "Multicast->IPv4 Multicast Configuration->IGMP Snooping", both are configured with "IGMP Snooping Status" and "IGMP Querier Status" enabled.   However, when I go to " Multicast->IPv4 Multicast Configuration->IGMP Proxy", and attempt to set VLAN1 as an upstream and VLAN2 as downstream,  I receive the following error message:  "Vlan 2: VLAN IGMP snooping querier enable prevents executing VLAN IGMP L3 querier enable."   If I disable "IGMP Querier Status" for VLAN2, then setting the IGMP proxy will work, however no packets are actually forwarded.   If I reverse the steps, creating the proxy first and then attempting to enable the querier, I receive this error message: "Vlan 2:  VLAN IGMP L3 querier enable prevents executing VLAN IGMP snooping querier enable."   Best that I can tell, IGMP Proxy is broken on the SG350.   Thanks, Denny   ...

Hello,   I am trying to set up bidirectional multicast across multiple VLANs with the SG350. I have the following interfaces defined:     Port 1 is an access port in VLAN1   Port 2 is is a trunk port, untagged VLAN1, tagged VLAN2, tagged VLAN3   Port 3 is is a trunk port, untagged VLAN1, tagged VLAN2, tagged VLAN3   My objective is to share (flood) multicast between VLAN1, VLAN2 and VLAN3.   Is this possible with the SG350? If so, I would greatly appreciate any information on how to configure.   Thanks, Denny   ... View more
