we currently have a network consisting of two Fortigate 100E devices running in a cluster, several Unifi Edgemax Fiber switches that act as kind of coreswitches and several Zyxel switches that connect to the office devices. The network topology is fully meshed with Spanning Tree enabled for redundancy.
Now I'm trying to introduce some Netgear Prosafe switches into that existing and working setup. I got it working so far, that i can access the whole network and all VLANs through the Netgear switches as long as the links are not connected redundantly. As soon as I plug in the second cable in order to redundantly connect the Netgear switch to the rest of the network, it stops working for all VLANs except for VLAN 1. What could be the underlying issue here?
As per checking, only VLAN 1 passes through without any issues. Please make sure that you enabled STP on the NETGEAR switches. Go to Switching > STP > Basic > STP Configuration. In order for us to assist you better with the issue, kindly provide us additional information. I have summarized my questions below:
May I know how did you setup the other VLANs on the NETGEAR switch?
What are the devices connected to it?
Are they VLAN aware devices?
How many switches do you have on your network?
I'm looking forward to your reply. You may also open a case / chat on NETGEAR support as it seems that this are new units and it's still under warranty. I suggest you to take advantage of the 90-days free support over the phone.
