Background: I was needing 802.3ad/LACP to aggregate ethernet ports from my main server and alleviate that bottleneck. After trying different load balancing options (TLB/ALB) on my old Dlink, I decided it wasn't worth the headache and started looking for something that properly did Link Aggregation.

I was looking at a similar Trendnet when I found this one from Cisco, looked at the reviews of both, and got the SG200-26. Had a couple of issues with LACP initially, but flashed the firmware to the latest and everything just works like a charm now. I'm very happy with it, and my main server has a 4Gb link now. I then bought a SG200-8 for an area that didn't get enough network drops, and setup a 2Gb link to it and fixed that bandwidth issue as well. I haven't gotten around to any QoS and VLAN settings yet, as that wasn't what I needed the switch for, but I'll probably use that in the future.

Maybe it's me (I am no network expert) but it seems every time I do anything with the network it's always a big deal. Things don't work, you have to go through page after page of the manual, calls to the tech support line to be on hold for an hour and then 3 calls later it's still not working.... You get the idea: Me and networks just don't play together well.


I mean this was as plug and play as it gets. I just pugged in my modem/router (2Wire provided by my ISP) into the ACT/Link port and then started plugging in computers, printers and other devices into the switch. Boom, in a few seconds, the network was done. Everything worked and every computer had internet access instantly and I could print to any printer w/o any issue (had to load printer drivers on a few computers that previously did not have access to one of the printers.) The only issue I had was not really an issue because I anticipated it. The 2wire modem/router uses the default ip of as does this switch. So I went to that IP to see which would come up (if anything). The 2wire came up. I went to the table of IPs on the 2Wire and saw the new IP the 2Wire had assigned to this switch. I went to that IP and up came the Cisco interface. I logged in, changed my username and password and logged out.

I haven't been into ether the 2Wire or Cisco switch since, and it all just keep working. I know these are expensive compared to the normal home router/switch/hub, but the ease of use is so much worth it. :)

Highly recommended and we'll be back to buy more.


Our network is now one 18PORT Sg 200-18 Gigabit Smart Switch and two 8 PORT Sg 200-08 Gigabit Smart Switches.

I purchased this unit due to a specific need for link aggregation (LAG) via LACP. Prior to the the purchase, I was using a Dell 24-port gigabit switch in my home, CAT6-based network. My new Synology 1813+ has the option for link aggregation and I wanted to take advantage of the connectivity option of 4 total ports. The Dell unit did not have LACP in the switch.

I've not owned a business-grade Cisco product before (despite their great reputation). After reading many positive reviews of this switch, I purchased the unit from Amazon. Setup was straightforward. I mounted the Cisco in my rack, moved the network cables from the Dell, and powered-up. The web-based setup is excellent and allowed me to configure a 4-port LACP LAG without any trouble. That is the last time I've had to interact with the setup interface for the switch. I'm seeing outstanding speeds that maximize the capabilities of the Synology 1813+ NAS unit and the other gigabit devices in my home. I'm very satisfied with the quality and speed of this unit and will certainly buy an additional unit if I need more ports over time.

At the time of my Cisco switch purchase, Synology did not list it among the switches that are "compatible" with their NAS units. I can confirm what other users have also noted, this particular switch works well with a Synology 1813+ in a 4-port LAG setup via LACP. I highly recommend this switch for its powerful, web-based interface and rock-solid network speeds. It is an excellent balance of quality, features, and price.

A switch is a switch is a switch, right?

Hmmmm....I learned the hard way that this isn't quite as true as I'd like.

In my search for a low cost switch with 802.3ad link aggregation, I began buying cheap, thinking that whatever I buy will work. There were some good and some not so good reviews of my first purchases, and when I purchased them, perhaps I got lemons, but either way, the end result was I threw away good money and wasted a lot of hours trying to get previously purchased competitor smart switches to work right.

In comes Cisco SG200-26 to the rescue.

This switch is made to spec. It does everything it says it will do with aplomb, never fails, and is just...well...rock solid.

Bonding 2 ports together for link aggregation is a relatively easy process, SNMP works well, and there are basic analysis and troubleshooting tools that all work to spec and work as the manual states.

I often make fun of Cisco, but in the networking space, I guess Cisco is much like a reliable volkswagon. It just works, and works well.

Now, having played around with a Juniper fanless switch, it's clear that if you have the money, the prices, reliability, and feature sets of switches get very expensive very quickly. So imagine my surprise that a switch this solid sells for such a low price.

There is a PoE version as well, and you have individual port control on that model of which ports get power and which ports don't, to save energy. But since I only have one PoE based IP phone, a single port injector is just about all I needed, allowing me to purchase this lower cost version.
