SRW2016 v03 to SG300-10 v05?

[fmarshall3]

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?

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.

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.
