GS752TP Vlan configuration to separate ports
I have several GS752TP switches and have had no issues in the past with various configs. Today I was setting up a new part of our building and wanted to use the 752TP as efffectively 3 switches. I h...
Crashing? Reads more like STP or the likes are shutting down a link to avoid some loop conditions. Review your L2 design and configuration.
Well, yes.... Which would be impossible if the vlans were separating the ports like they should be.
Each group of ports is set up untagged to themselves and no access to the others, but the issue persists. Exact same setup on HPE 3500YL works perfectly. I know the GS752TP isn't an enterprise level unit, but it's got to be able to segregate between ports right? Is there a setting somewhere that tells vlans to isolate from eachother that I'm missing?
Appears you think STP and RSTP is limited to each VLAN - I have to disappoint you, I'm afraid. It's irrelevant if we talk of Netgear or any blue heavy iron - this applies to any brand.
If you are very happy, -and- there is neither STP or RSTP, nor any other L2 loop protection in place, -any- switch will take every VLAN as a dedicated entity, each with it's own IP subnet and broadcast domain.
lol, so it's impossible to have 2 separate networks on separate ports on a netgear GS752TP?
Obviously the issue isn't applying to "any brand" as I have a switch working exactly as I specified as I type this. The issue is either the setting on this switch or the capabilities. This isn't a difficult task I'm asking the switch to do, and it's not rare.
There should not be any storms when ports are separated into vlans with no access to each other. There are no loops as both connections come from separate networks completely. For what it's worth, it seems to work with the RJ45 ports but fails when I utilize the SFPs.
One physical switch will always make up one network. And of course, you can configure multiple VLANs making up multiple dedicated broadcast domains.
Yes, you can disable STP globally, disable STP by port, and disable BPDU forwarding, IGMP forwarding, MLD forwarding, ... if not required. That's about everything coming into my mind on the fly.
Last but not least: I'm just another user here, not Netgear.
