My first question is: Can a VLAN set up on an SRW2016 v03 be trunked to the same VLAN on an SG300-10 successfully?
I have this:
RV320 router in very simple gateway mode - no VLANs. DHCP enabled.
{ RV320 LAN port}
{SRW2016 v03 Port, Access, VLAN100, Untagged}
{SRW2016 v03 Port, Trunked VLAN1 Untagged, VLAN100 Tagged}
{This works to get DHCP on VLAN100}
{SRW2016 v03 Port, Access, VLAN100, Untagged}
{this works to get DHCP on a laptop which is not VLAN aware}
{SRW2016 v03 Port, Trunked VLAN1 Untagged, VLAN100 Tagged}
{This goes to trunked port on SG300-10}
{SG300-10 v05 Port, Trunked, VLAN1 Untagged, VLAN100 Tagged}
{SG300-10 Port, Access, VLAN100, Untagged}
{Laptop gets DHCP service on VLAN100}
{SG300-10 Port, Trunked, VLAN1 Untagged, VLAN100 Tagged}
{VLAN aware VOIP Phone does not get DHCP service on VLAN100}
{Switch sees phone MAC address on VLAN1}
So, in words: VLAN100 works fine on the SRW2016 it appears.
However, when trunked to an SG300-10, VLAN100 works coming out of a VLAN100 access port but not out of a Trunked VLAN1/VLAN100 port.
Is this to be expected or is there something subtle that needs to be done?

Thanks.
I did find the problem. A VOIP phone connected to the downstream SG300-10 trunked port initializes on VLAN1 - so that gave the impression of what I described.

I don't think it is the SG300-10 switch trunk issue. I have a SG300-28 in layer 3 mode feeding a SG300-10MPP switch in layer 2 mode. The SG300-10 is powering some WAP371 APs using trunks as I have 2 SSIDs on the WAP371 wireless units which are on separate VLANs. Both SSIDs on separate VLANs get the correct DHCP IP addresses. The SG300-10MPP is connected to my SG300-28 with a trunk port.
