My setup is currently:
[Layer 1] CenturyLink Fiber ONT modem/router thing
-> [Layer 2] TP-Link switch (for VLAN tagging)
-> [Layer 3] Orbi router hub
-> [Layer 4] 10-port Gigabit switch
-> [Layer 5] Everything else (wired Orbi Wifi mesh, some other devices).
I just bought the Orbi router stuff, and it supports 2.5 gigabit ethernet, but I’m currently limited by my gigabit switches. I’d like to bring everything up to that 2.5 gigabit floor.
Is it possible to use a single switch for this, like so?
[Layer 1] CenturyLink Fiber ONT modem/router thing
-> [Layer 2] 2.5Gb switch
-> [Layer 3] Orbi router hub
-> [Layer 2] Back to the same 2.5Gb switch
-> [Layer 3] Everything else (wired Orbi Wifi mesh, some other devices).
I didn’t consider this originally because I was thinking of them as a chain, where the device providing the VLAN tagging would have to ONLY do that. But since that configuration is per-port, this seems like it might work. But I’m a noob, so I need your help.
Doable.
Create access vlan 200 on port 1 and 2. Create access vlan 100 on port 3 and 4+.
Isp modem to port 1 Mesh Wan to port 2 Mesh LAN to port 3 Rest of LAN on 4+
Only question is, do you need to do that? You can just go from isp to orbi and then from orbi to switch. Only reason to set this up this way would be if you did home labs with static ips.
Assuming a quality managed 2.5gbps switch, this topology should be no problem.
(FYI, the terminology “Layer 1” etc has special meaning in networking, might want to choose a different way of denoting your segmentation)
Totally doable with a managed switch. You just need to put the port connected to the ONT and the port connected to the router’s WAN port into their own VLAN, and not have them on any other VLAN.
