GS110EMX: 10G ports throttle uploads to 250-300 Mbps
I've been going back and forth with Netgear support for over a week about this and I'm honestly at a loss. I'm hoping someone here can tell me if I'm crazy or if what they're telling me doesn't make sense, because it really doesn't add up to me. My Setup Switch: Netgear GS110EMX (firmware 1.0.2.8) Port 1: Internet uplink (1G, connected to router — standard fiber ISP) Port 9: Mac Pro via OWC Thunderbolt 4 to 10G Ethernet Adapter Port 10: Asustor AS6508T NAS (10G) Cables: Cat6A throughout This is exactly why I bought this switch — two 10G ports for my computer and NAS, with everything else on the 1G ports. Pretty standard home prosumer setup. The Problem Internet uploads are throttled to about 250-300 Mbps when my computer is on a 10G port. Downloads are fine at 830-880 Mbps. When I move the same computer to a 1G port with the exact same cable, uploads jump to 708 Mbps. That's more than double the speed on a port that's supposedly 10x slower. What I've Tested (at Netgear's request) I ran every test their L3 support team asked for. Here are the results: Internet Speed Tests (computer on 10G port 9): Flow Control Download Upload OFF 865 Mbps 306 Mbps ON (port 9 only) 879 Mbps 169 Mbps ON (both 9 & 10) 820 Mbps 137 Mbps Internet Speed Test — computer on 1G port (same cable, same everything): Download Upload 884 Mbps 708 Mbps iPerf3 between Mac and NAS (local, 10G ↔ 10G): Direction Speed Mac → NAS 3.73 Gbps NAS → Mac 9.40 Gbps Local 10G performance is excellent. The ports, cables, and NIC all work fine. What Netgear Says After all this testing, support came back and told me: This is "working as expected" and "within the design limitations of the switch" The 10G ports are "intended to be used as uplinks" — not for client devices A replacement would behave the same way My configuration is "not the intended use case" Why I'm Confused I don't understand how any of this is "expected behavior." Specifically: How does a 1G port give me faster uploads than a 10G port? If the 1G uplink is the bottleneck, moving to a slower port should give me equal or worse speeds. Not more than double. Nobody has explained this. Why are only uploads affected? Downloads through the 10G port hit 865 Mbps — nearly saturating the 1G uplink. The traffic crosses the same 10G/1G speed boundary in both directions. Why would only one direction have "buffer overflow" problems? Flow Control made things WORSE. They asked me to enable it. It dropped uploads from 306 Mbps to 137 Mbps. How is that a fix? The product page says "No Network Bottlenecks thanks to the 2 10-Gigabit/Multi-Gigabit Uplinks." Now support says those ports are only meant to be uplinks and my setup is unsupported. The user manual literally shows 10G client devices connected to ports 9 and 10 in its network diagrams. This switch used to work. I used the exact same setup with fiber in Chicago for years with no issues. I only noticed the problem after switching to fiber here in LA recently. Something changed. What I'm Asking Has anyone else seen this? Am I wrong to think a managed switch should be able to handle 10G devices sending traffic through a 1G uplink without losing 70% of the uplink's capacity? I've seen a couple other threads about similar issues with the GS110EMX and I'm starting to think this is a known design flaw that Netgear just doesn't want to acknowledge. At this point I just want to know if I should keep fighting for a replacement or just give up and buy a different switch. Any insight would be really appreciated. I've spent way too many hours on this already.GS752TPV3 "comcast uplink port"
Howdy All, We have instrumented our first "new to us" Netgear switch for our classroom (to replace like 7 smaller switched that were scattered around) and I got it up and running, but realize that PORT 7 is the "uplink to our comcast router" port and now we're putting a new classroom computer onto that port, so I need to move the uplink line. I tried changing the VLAN to include Port 48 and Port 39 (both free in our schema) and moved the network line, but the switch refused to route traffic. I rebooted the switch (not reset, restart) to see if "coming up on the new line" would work, but no. If I move the line back to port 7 (still in the VLAN) it resumes functionality. I have checked the port configurations in the switch web admin, and they are identical. I have checked the VLAN membership configuration, and all three ports are "U"ntagged, with the same attributes. Any ideas? Thanks in advance
Help: Auto-VoIP setting to correct VLAN, but also incorrectly on default
We are trying to configure our S3300's to utilize Auto-VoIP. The goal being that all devices with the correct MAC prefix will be pushed onto the VoIP VLAN regardless of device settings, and without having to manually adjust VLAN assignments on our switches. We have the default VLAN for normal network traffic (PCs, printers, etc), and have Auto-VoIP set up on VLAN 88. We've added several MAC prefixes for our phones. We have our FortiGate firewall configured with two LAN segments. The first for PCs, and the second for VoIP. Both of them are set to the default VLAN ID. The FortiGate subnet used for VoIP has its MAC address set to match a Poly prefix. When it is plugged into a Netgear S3300 switch, it shows up on both VLAN 88 and VLAN 1. It should only be on VLAN 88. Since the Fortigate is configured to do DHCP duty on the VoIP LANs, this is a problem: a non-VoIP device will pull an IP address from the VoIP LAN. The MAC address 80:5E:C0:09:00:05 should only be on VLAN 88. Since it's also showing up on VLAN 1, when I plug a laptop into the switch, it will pull DHCP for the VoIP network. That needs to not happen. Any idea what we're doing wrong? Any help greatly appreciated!GS752TP Firmware Upgrade Failed
I attempted to upgrade a GS752TP from firmware version 60.0.1.16 to 60.0.1.30. I followed the instructions here, just with the 60.0.1.30 firmware instead of .24 as shown in the instructions. When I rebooted, the switch powered up, but I cannot connect to it in any way. The Power LED lights up and alternately switches between green and orange very slowly (maybe once a minute). The LED Mode LED is on solid green. When the Power LED is orange, the port 37 and 43 link LEDs light up solid regardless of if anything is plugged in. When the Power LED is green, whatever ports I plug into will light up solid orange. The LED Mode LED stays on solid green the whole time. I've tried pushing the "Reset" and "Factory Default" buttons on the front and they don't seem to do anything (i.e. - it doesn't reboot/reset as far as I can tell). I've tried connecting to Smart Control Center, but nothing shows up. I've tried the default IP's I can find in the documentation (192.168.0.239 and 192.168.1.1) and I can't access the web interface. Obviously, something went wrong in the upgrade process, but I'm really not sure how to even troubleshoot since the switch is basically non-responsive to anything I do.GS724TPv3 The switch loses IP connection about 1 time in 5 days.
Hi, I have Netgear switch GS724TPv3, newest firmware installed The switch loses IP connection about 1 x every 5 days. I don't know why? While power supply of IP cameras powered via POE is maintained. IP connectivity from router and connected devices to switch is lost. After hard power off and on of switch everything works. The restart pin on the front of switch does not restore connectivity, it requires complete power off. The switch has a static IP address to avoid problems with address reservation from DHCP router. Looking for a solution to the problem of setting up a reboot script for switch GS724TPv3 from my NAS Synology via ssh or telnet. Can someone with experience help me with writing a script. Thank you Zbynek
VLAN Routing for Newbies
Howdy All, I've recently decided to install a GS752 switch in our offices to segregate traffic to help with security. I've run into a problem that I'm hoping someone can help me with (to keep things simple I'll just go over what VLAN 1 and VLAN 10 look like): VLAN1 - is fine. Systems attached get IP addresses from DHCP server, and can reach the internet. All ports are Untagged "U" in the port membership image. (Port 1-10) VLAN10 - doesn't work. No DHCP traffic through and no access to the internet even when using a static IP address in range. All ports are Untagged "U" in the port membership image. (Port 1, 11-20) My setup is: Broadband Router -> Firewall -> GS752 -> VLANS as follow: VLAN 1 - NAS, DNS Server, DHCP Server, Wifi APs VLAN 10 - PCs How do I allow DHCP and DNS to service VLAN1 and VLAN 10, as well others?
