I would like to help with what I believe, it is a problem of routing VLANS on a SLM2008 and RVS4000

Please see attached Word documentfor a full description.  Thank you!

Hi Michael,

All those who say the VLANS within the first hour is a person much smarter than me.

I have to admit with great humility, I think it took me nagging questions for some patients (AR) and weeks and weeks until finally I have a bit of understanding of the functioning of VLAN.

So don't feel concerned, many people there are in the same "boat" as you.

But VLAN, when you get the feel for them, are so so helpful.

I like under 'acceptable frame type' tick 'all '.

The value PVID tells me basically what VLAN not signposted port is underway.

This means that in the image below, 3 ports, 6-8 will be I hope, expecting to received and transmit frames Ethernet labeled with a tag VLAN 2.

But on the diagram above, I can now make room for the following table.

without tag vlan tagged vlan

3-1-2 switch port

6 2 2 switch port can not be marked and unidentified on the same switch port

7 2 2 switch port can not be marked and unidentified on the same switch port

8-1-2 switch port

In the diagram above, I can see that 1 and 2 switch ports are ifor untagged VLAN 3 so the packages roll inside the switch for VLAN 3 will have their VLAN TAGs removed from the Ethernet frame as the traver packets on the switch to an IP host.

I also see that the switch port 3 unidentified in the VLAN 1, but you have set the acceptable frame on tagged only type.

Unless I read this all in fact wrong.

Note: I have to admit that has the big brother to the SG200 SG300 series switch,

Don't forget about PC / security cameras (except Cisco, hey I'm system engineer have to give my equipment fitted with a plug) in most of the cases do not send frames labeled Ethernet in the switch, which is why I like the idea of accepting all types of frames. I guess that the default VLAN settings are the acceptable frame types = all

When we add a vlan to a switch port, as the image below, switch to these ports are added as a vlan tagged, because the port if already reside in one VLAN not tagged...  This means that in the case below, 3 ports, 6-8 will be I hope, expecting to received and transmit frames ethernet labeled with a tag VLAN 2.

You said it, not easy, you need to play and practice with switching and routing

.  But the general rule that I follow for VLAN's.

A switch port can be untagged in a single vlan, but at the same time marked on several VLANs.

With respect to the limitation of the camera, my camera, I have not used my filters. But there is the possibility of limiting access by IP address or network.

I guess you can find an article on your DLINK camera to filter. Reset the default camera and try to add it again.

Routing between VLANS will occur at the RVS4000, it routes packets between different VLANs, the SG200 cannot be put in Layer 3 mode like its big brother the 300 series (SRWXXX-K9-NA)...

Best regards, Dave
