This 4 LAG group limitation applies when you have more than four devices that support LACP. For example, if you have two Synology NAS devices with two or more ethernet ports and three computers with two or more ethernet ports, all supporting IEEE 802.3ad LACP.
The switch allows the user to place more than two ports in a single LAG group, but this flexibility is useless for my needs connecting multiple Synology NAS and computers.
Nowhere on Amazon's product listing does this limitation appear and it is not prominent on Cisco's product specifications page. Does Cisco provide any explanation for the limit? None that I could find . . .
By comparison, two NETGEAR ProSAFE GS108T 8-Port Gigabit Smart Managed Switch (GS108T-200NAS) will provide 16 ports and a total of 8 LAG groups for less than the cost of the Cisco SG200-18 switch.
After about 10 days of use, I am still considering whether to return the switch. It has many positives: lots of software features, a built-in power supply (no power brick), and runs cool. For all these positives, it fails in the primary reason I bought it and that is to support more than 5 devices with IEEE 802.3ad Link Aggregation Control Protocol.
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.
Long story short, I've upgraded the 2 star to 4 star. The hold back on the 1 star was primarily more of a user intuitive/friendly interface that resulted in my facing these issues. I called Cisco tech support, and they were really friendly and helpful. The only issue was their lack of Mac OS knowledge, so it was harder for them to resolve the Boot Code Update.
1) This was related to settings were not automatically saved. I saw the "(x) save" flash periodically, but I thought it was an auto save feature letting me know things were being saved. It would flash on and then disappear, making me think it was a notification. Instead, it was actually a 'warning' that my changes were not being saved until I hit the "(x) save" status.
2) The reason I couldn't get past the fourth oldest firmware upgrade, was that other firmware upgrades required the boot code to also be upgraded. And unlike the firmware which allows for HTTP update via a web browser, the boot code upgrade required TFTP protocol to update (this is where the Cisco Techs were having issues figuring out how to do this on the Mac. And they couldn't figure out how to make SCP work, and HTTP was not an option for this feature). Eventually, this was resolved, but this took the bulk of the time.
Less significant issue: Setting the date/time of the switch 'automatically' through polling of a server/service on the internet. Typically other routers that I've purchased from Cisco or Netgear, this was an easy 'check box' like feature to enable. On this switch, the server names that are available to chose from were not working, but eventually, through searching, we found a server that provided this service and entered the IP address into the system and it worked.
All in all, it's working great so far. Only have 7 lines hooked up, but plan to migrate all the other ethernet connections over time, and leverage about 7 of the PoE's.
After reading so many rave reviews, I decided to go for the SG200-50P. This is an unmanaged 50 Port (24 of which are PoE capable) switch.
What works well:
1) works out of the box based on the instructions. Hard coding the Computer's IP, I could reach, sign into and configure the Switch. I set its IP (versus allowing the router to DHCP, set its IP address. I reserve a range of IP addresses for devices I want to conveniently log into ), changed the password (prompted when you first log into the switch), and set the system's date/time.
1) anytime I reboot, I lose all the settings I made above (date/time, password, static IP assignment, just these simple settings so far. I don't want to invest more time until I figure out why a reboot resets these to the default. . It doesn't reset the static IP of the switch to 192.168.1.254 (out of the box), but instead resets it to DHCP to receive an assigned IP).
2) there was four new firmware updates available from Cisco's site. I was able to successfully install ONLY the 22.214.171.124 version. The other three versions met with errors upon attempting to install them. Either size too large (install died after 97%) on the next version, or it simply gives error of "install failed" after loading 2% on the two afterwards. After these failures, I had to reset the switch and install the first upgrade, otherwise the menu system behaved erratically after a failed firmware upgrade.
These two big issues leave me disappointed. I will try tech support to see if I can resolve the issue. I hope it's easy to fix remotely without me having to send this item back.
Years ago, I was a die hard Cisco fan, but then switched to Netgear after a series of quality issues with their home routers (the Pancake version, their WRT series were awesome until one day it finally died). But after reading these reviews, I was tempted to give them a try again. Disappointing so far. :-(
A less significant issue, more annoying than anything else is that the fans are quite loud. The thing runs pretty cool from what I can tell so far, so I guess it does its job, just rather loudly. Also, the instructions says there is a 'spacer' for the mounting bracket for the rack, but there was no spacer for either bracket.
Cons: None, but be aware if you get PoE version
The small business series of switches are awesome for what they bring to the table in comparison to other small business offerings. I've deployed about 70 SF PoE switches and never had a problem with any of them. Be aware that, if you need PoE, you should probably go up to the 300 series.
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.
