Adding SFP to conenct from GS752TPPv3 to LG TV ... Help!!
Evening all, I have 2 GS752TPP's in a home environment. They were new last year and I have Insight installed. We have RJ45 cat 5e to Cat 6 flood wired throughout the property which works very solidly connecting things like TVs, Sonos boxes, PoE cameras, streaming boxes etc. There is also an Orbi wifi system for mobile devices, laptops etc. I'm currently re-wiring a room to facilitate a new up to date TV and Sonos home theatre system and have the opportunity to install fiber HDMI and fiber to the TV. It's not strictly necessary but given the roof and walls are stripped out and I can install a conduit, it seems worthwhile to grab the opportunity Have looked at articles and can see roughly what I might need but I'm having trouble translating this into Netgear products. The switches are in a room approximately 10 meters from the TV. The area behind the TV has been channelled out such that I can install a hub or media converter, cables and power. I know I need an SFP module at the switch. Currently there are none fitted. If I read correctly, it is the ideal to have the SFP module at each end. But past that, I'm a bit in the dark. Would appreciate any advice, product suggestions, how I could connect the 752TPP to the TV in fiber to get the fastest, more robust, future proofed connection and configuration please. I've read about third party SFP's that are brand independent but would prefer keep the entire home network Netgear if humanly possible. Appreciate any advice so that I can get it right first time. Many thanks
IPv6 / DHCPv6 with S350 Smart Switches (GS324T / GS348T)
Wie Renefw in diesem Thread gemeldet hat funktioniert die IPv6 Adressvergabe von z.B. FritzBox Routern nicht über S350 Smart Switches. Die Clients erhalten keine IPv6 Adresse und können somit keine IPv6 Seiten im Internet öffnen. Ich hatte das gleiche Problem an meinem GS348T und konnte das Problem durch Deaktivieren der IGMP-Snooping-Konfiguration lösen. Ich habe diverse IGMP-Snooping-Konfigurationen getestet aber alles ohne Erfolg. Nur das Deaktivieren der IGMP-Snooping-Konfiguration hat letztendlich geholfen. Viel Glück, wenn Ihr das gleiche Problem habt. ✌MS510TXM Firmware authenticity validation
Netgear does not digitally sign firmware updates nor are any hash values (such as SHA-256) provided for the firmware. This seems very irresponsible and highly unprofessional. It makes it essentially impossible for a customer to validate the authenticity of the firmware. Why doesn't Netgear provide these basic protections for their customers?GS348T Flow Control (Flusssteuerung) & 802.3x Pause-Frames
Hi, ich betreibe einen Netgear Serie GS348T S350 – 48-Port Gigabit Ethernet Smart Managed Pro Switch mit 4 SFP Ports in meinem Netzwerk und sehe nun ein Problem mit Flow Control (Flusssteuerung) in Verbindung mit FRITZ!Repeater 2400. Ich betreibe 6 von den FRITZ!Repeater 2400 in meinem Netzwerk als LAN-Brücke und alle 6 haben seit neuesten das Problem, dass sie nach einer undefinierten Zeit immer Offline gehen. Nach Werkreset und Deaktivierung von diversen Sicherheits und Switich Features bin ich am Ende beim Flow Control (Flusssteuerung) gelandet. Der Grund für den Ausfall ist, dass der Netgear Switch auf einmal 802.3x Pause-Frames vom FRITZ!Repeater 2400 empfängt und daraufhin keine Pakete mehr weiterleitet. Im Fehlerfall steigen die Counter bei: Gesamtzahl empfangener nicht weitergeleiteter Pakete 124538 802.3x Pause-Frames empfangen 124538 kontinuierlich an. Das Problem löst sich dann auch nicht mehr von selbst, da wahrscheinlich keine Reset Frames gesendet werden. Erst ein Link Up/Down resetet das Problem, es taucht aber Minuten später wieder auf und das Spiel beginnt von vorne. Das Kuriose ist, dass der Switch dies auch macht, obwohl Flow Mode im Standard auf allen Ports Disabled (Deaktivieren) ist. Deaktivieren- Wenn die Flusssteuerung deaktiviert ist, erzeugt der Switch keine PAUSE-Frames. Der Switch drosselt auch nicht die Paketübertragung beim Empfang von PAUSE-Frames vom Partner. Aber genau das tut er, basierend auf dem ansteigenden "802.3x Pause-Frames empfangen" Counter. Scheinbar schient dies auch ein Problem mit den FRITZ!Repeater 2400 zu sein, da nur diese Endgeräte aktuell bei mir die 802.3x Pause-Frames senden. Egal, ob die FRITZ!Repeater 2400 aktuell viele WLAN-Clients haben oder nicht. Sie steigen bei mir fast immer gleichzeitig aus. Wie kann es sein, dass der Switch auf 802.3x Pause-Frames reagiert, obwohl diese Funktion deaktiviert ist? Switch Details: System Description.............................

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
