SG3100 OPT1 provisioning

[jd3]

Hi,

What is 'behind' OPT1 on a SG3100? Is it a switched port? Can I trunk VLANs via that physical port? What is throughput?

Cheers,
JD

@jd3
"Two 1 Gigabit Ethernet Ports, configured as dual WAN or one WAN one LAN
plus four-port 1 Gbps Marvell 88E6141 switch, uplinked at 2.5 Gbps to the third port on the SoC for LAN."

@jd3 I don't have an SG-3100, but it has always been my understanding that the WAN and OPT1 are discrete network ports, in other words separate interfaces. They should both have a throughput of 1Gbps, or about 940Mbps-ish actual. It really depends on what's plugged into the other end if you will see these speeds, but that's what they support.

Yes, you can pile lots of VLANs onto the OPT1 port thru the VLAN tab under Interfaces. It's really easy. Are you using the correct term "trunk" in your question? I'm asking because trunking is usually used between 2 switches and carries multiple VLAN networks. Is this what you are trying to do?

If you're interested, here's also how to do it to the switch ports:

Hope that helps.

Just to confirm that is exactly right. WAN and OPT are discrete NICs, mvneta2 and mvneta0.
LAN (mvneta1) is connected to the switch internally.
