Sorry for the new thread but the other thread didn't seem appropriate to ask this. I have a L2 POE switch and an unmanaged switch running in a flat network. I'm about to add Voice to the LAN along with more CCTV cameras and want to separate the traffic.

 

I *think* I need some sort of L3 device to route my VLANs and was thinking of the following topology:

Is an ER-X a good way to do this? Will it work?

You have a fairly large potential bottleneck with a "router on a stick" design. Personally I'd just buy a 48 port L3 switch to replace the existing switches. Have a look at the EdgeSwitches if you like Ubiquiti.

Thanks, that was the original plan until I saw the cost of these big L3 PoE switches. I then thought about an older 3750 PoE but they are big and noisey and might cause me issues with PoE standards. 

 

How much of a performance bottle neck would you expect with the router on a stick design? CCTV and VoIP traffic and would largely be a single broadcast domain on the L2 switch. It would be the wireless traffic (minimal) and management of the CCTV that would be routed. 

 

Do you have any recommendations for a good value PoE L3 switch?

A 48 port Ubiquiti EdgeSwitches with L3 and POE is sub $1500 on PriceSpy, the list prices for the big boys e.g. Aruba, Cisco, Juniper etc are pretty steep, but if you talk to the right people those prices do come down. We upgraded to Aruba last year (8x 2930F, 2x 5406R with extra modules, small mountain of DAC's, SFP's etc) and what we got was getting close to 100k on pricespy prices, but we paid half that via an HP Platinum partner.

Hi, if you after well featured L2+/3 switch with POE you might like to look at the TP-Link T1600-28PS, which PBTech have to around $590.

 

TPlink is not a brand I would have normally gone for, but for a SME project recently I had a $350 budget and needed static routing and LACP links, so I went hunting and ended up with the T1600-28 which is the non POE version of the same switch.

 

I was pleasantly surprised with what I got, its operated just as advertised, the GUI is logical and straight forward, it also is fully CLI configurable and again very cisco ios esq so pretty straight forward.

 

Edit: be aware of the Mikrotik CRS option using RouterOS, those switches are great, when using SwitchOS and L2 functionality, however to acheive L3 you need to run RouterOS and they are not very speedy, at least the TPlink uses a proper Broadcom switch processor that offers wirespeed L3 routing.

Thanks @cyril. Picked up a T1600 this afternoon and will configure it over the weekend. Looks like it'll tick all the boxes.

Hi, good one, at first I was hesitant about buying a TPLink for this level of switching, unfortunately for me the Server guy spent all the money on flash SSD's leaving me about $700 short of the money I wanted to spend on a switch, so had to go hunting.

 

Now I have deployed the T1600 I have to say I am impressed, its very well built, the CLI is pretty familiar and the Gui seems well sorted. The features are all there that I require, vlans, link aggregation with the ability to set L3+L4 hashing and L3 static routing, all for $350 which is about $1k less than I would have expected to spend on a 24port wtih 4 additional SFPs. So far having been in service for 3-4months it just does it business, look forward to hearing your comments after a weekend playing.

 

Cyril
