I'm using an SRW2016 switch for a small office central LAN switch.
I'm adding a new subnet for VOIP - for a variety of good reasons.
The new subnet will have its own separate internet gateway and ISP - which is one of the good reasons.
This much is all set and working up to a point.
Here is a diagram of the setup:
Gateway<>SRW2016 Port 9 VLAN1 default untagged
RV042 <>SRW2016 Port 16 VLAN100 <<<<<<<<<<<<< ??
LAN <>SRW2016 Port 8 Trunked VLAN1 untagged / VLAN100 Tagged
LAN <>SRW2016 Port 12 Trunked VLAN1 untagged / VLAN100 Tagged
Of course, the idea is that all VLAN100 traffic flow through port 16 and to the internet.
My need for learning is how to set up the ports on the SRW2016 - particularly, it seems, port 16.
In the original configuration, the switch had just a "vanilla" switch configuration: connecting single gateway to all the LAN connections on the untagged default VLAN1.
Setting up for the new subnet, I set up VLAN100 which is tagged (there are other switches cascaded "down" thereafter).
The other switches have the same VLAN100 added and all the VLAN100-related ports are trunked on those switches.
The ports on the SRW2106 connecting to those switches are also trunked.
A new gateway has been configured (an RV042) which will provide gateway and DHCP service on a new subnet intending to use VLAN100. The router LAN is connected to a port on the SRW2016. I intend that the new router be VLAN unaware - just connected to VLAN 100 via an untrunked connection.
What doesn't work is internet access from VLAN100 devices.
I believe this is due to how the port for the new gateway is configured in its switch port.
The choices are General, Access and Trunked / Tagged and Untagged.
Also, I can connect a computer to the LAN side of the added RV042 and can ping internet addresses.
But, when I connect the LAN side of the RV042 to port 16 the switch, that ping traffic stops and I have to disconnect from the switch and reboot the router...?? At that point, the ping traffic resumes.
Probably a lot that I don't know or understand....
