If you're looking for a netgear PoE switch in this price range, you will be comparing 3 switches:
~£60 NETGEAR GS308P-100UKS 8-Port Gigabit Switch with 4-Port PoE which is completely unmanaged
~£75 the switch this review is about, 'plus' web managed - otherwise essentially identical in specification to the unmanaged GS308P.
~£100 NETGEAR GS110TP-200EUS ProSAFE 8 Port Gigabit PoE Smart Switch which is fully managed: (this has PoE on all 8 ports, but still has the same overall 53W limit for PoE so if you are using, say, 12W IP cameras you will still only be able to run 4 before you run into the limit).
I'm not comparing it against non-Netgear switches as I can't find anything else in the same price range that's actually a reasonable comparison. The non-Netgear ones are either substantially more expensive, or have known compatibility issues or are unable to supply the full 15.4W PoE power meaning some IP cameras won't work.
The big flaw is this switch is that the PoE part of the switch is COMPLETELY UNMANAGED. I can't overstate that. The web interface cannot even display the state of the PoE leds on the front of the switch. The web interface can "reboot the switch", but this doesn't reset the PoE ports. It won't display the power usage on the PoE ports. It's really bordering on false advertising. Netgear support have confirmed this limitation and state that it is a limitation of the hardware (i.e. it can not be fixed by a software update).
If you want actual management of the PoE, you need to go up to the £100 switch.
That means this switch falls into a very narrow band of when it would be a sensible purchase. Unless you need VLAN, QoS, port status info or port mirroring, you are probably better to just go for the cheaper unmanaged switch.
You can see non-PoE status for each port in the web interface - up/down state, speed, etc. It even has a nice feature where if a port is down it will estimate how far away any break in the cable is. If you want to manage or see the PoE status, or see the router MAC table, or use SNMP, you need to go for the more expensive fully managed switch.
Another flaw with the 'plus' web management implementation on this switch is that it becomes slow and unusable as soon as you start streaming from any IP cameras connected to the switch. This is because *all* HTTP traffic (whether it is destined for the switch's IP address or not) is forwarded to the management processor, which isn't powerful enough to cope so ends up dropping over half the packets even with just a single camera stream.
It also seems to have a bug that if the DHCP server if not available when the switch tries to get it's management IP it never seems to try again, I had to power cycle the switch manually to be able to talk to the management interface. (In the long term, you should reconfigure the management interface to have a static IP of course, making this irrelevant.)
Otherwise, the switch does seem to work well. No reliability issues. PoE powered by IP cameras fine. It doesn't have a fan, so is silent. The switch has a lifetime warranty (the unmanaged one has a 2 year warranty), although the PSU only has a 2 year warranty. Replacement PSUs (specification is 48V @ 1.25A) do not seem to be readily available, which is a small worry, but I presume in time they will become available.
Personally, I was very disappointed by this switch, and returned it to Amazon for a refund and bought the cheaper unmanaged version. I was tempted to go for the fully managed one instead, but the price premium wasn't worth it for me.
Kurzum: Der Switch wird als "Pro", "Managed" und "Smart" verkauft. Das mag für die normale Switch-Funktion stimmen. Bei der POE-Varianten vermisst man das gänzlich. POE ist per Default aktiviert, weder überwachbar und am allerwichtigstens: Nicht abschaltbar.
Wenn ich auf eine Leiter klettern muss, um bei meiner POE-Kamera den Stecker zu ziehen, weil es keine andere möglichkeit gibt diese abzuschalten, dann ist das nicht "Pro", "Managed" oder "Smart".
Es ging zurück. Habe ein Konkurrenzprodukt erworben, dass nur halb so teuer ist und neben einer Leistungsüberwachung auch das Ein- und Ausschalten als elementare Funktion selbstverständlich unterstützt.
Der Switch funktioniert anstandslos und die Verarbeitung ist gut. Aber dazu muss man nicht zur teureren PEO-Variante greifen. Deshalb gibt es einen Stern.
This does not work with the BT Wholehome Mesh WiFi, when ever I plug even just one of the disc it kills the link between this and my Virgin Media router. Thought it was a defective switch at first, but the replacement was exactly the same. Enabled Looping detection, even though I shouldn’t have to as the Mesh Wifi issues it’s own spanning tree packets. Tried changing from dynamic to software broadcast forwarding, which to me made no sense as it was only using the default VLAN, but it was worth a try. Everything else at this point was disabled, QoS, IGMP snooping etc etc. I’m not sure what’s the issue, but now I’m using my old Netgear Unmanaged switch and it all works fine. Returning this as it simply does not work with my setup which I would of thought is quite common for anyone wanting to purchase this type of switch. Shame as there’s not many 24port gigabit poe switches out there at this price range.
The VLAN configuration has four separate modes of operation, only one of which can be enabled at a time. The most useful of these is "802.1q Advanced " mode. Changing to any other VLAN mode deletes the existing VLAN config and you'd better hope you kept a note of the config, as you will have to do it again. The VLAN config is rather basic to understand. Click the port to toggle between "U" (untagged) "T" (VLAN Tagged)" and none (Port not in the current VLAN).
Unusually, a port can be a member of multiple untagged VLANs. This is not "true" standards-based VLAN separation but allows a degree of segregation within the same subnet, for example, If for example you had a Guest WiFi and an Internal WiFi and wanted to isolate the two, but have both share the same router and printer, this feature might be useful if you didn't want to configure VLAN tags on the router of if the router does not support VLANs. Anything else (e.g. server access) is probably best done using users/passwords that are allowed/not allowed to access server resources.
If you have multiple switches and want to support multiple VLANs across the network, you will need to use "802.1q Advanced mode", and tag all the VLANs on the ports that are connected to the other switches, doing the same at both ends. This should also inter-operate with any other switch or device supporting the industry standard IEEE 802.1q VLAN tagging.)
It does support a mix of tagged and untagged VLANs on a port, for example VLAN 1 untagged (native) and VLANs 2 and 3 tagged. This allowed me to roll out the VLANs and migrate things gradually one at at time, rather than having to turn on VLANs, break the existing network, and have to run round and configure VLAN tags on everything in one go.
If deleting a port entirely from the default (or only VLAN) then it will complain every time that the PVID is wrong. You will need to add the port to the new VLAN first, change the PVID in a different page, and then go back and delete the old VLAN. Clunky.
Device only has a singe password for config access, it has no concept of usernames or access levels.
Also there appeared to be no way to isolate the device's management IP from the VLANs. (E.g. designate which VLAN is the management VLAN.) It is accessible on all VLANs. It would appear that the simplest config is to leave VLAN 1 intact everywhere and then add additional VLANs and tagged ports as needed, starting from the device furthest away, configure the port tags. This is so fiddly that I added a handful of VLANs at the same time, so if I need an extra VLAN, I don't need to configure it all again.
Current version of firmware does not allow you to see which MAC addresses are learned on which port, or via which VLANs, so this is a big fail for being able to do any network troubleshooting, or if you need to locate a device on the network. This is a very basic requirement for any network switch. It does not allow a description/note per port either, so no helpful reminder of what's plugged in to which port.
The switch comes with the usual CD which goes straight in the bin. Instruction leaflet fails to mention the default IP of the device.(Had to look that one up on the Netgear site) It can be configured via web interface, or by some rather strange windows software which is mostly useful for setting the IP, otherwise it's identical to the web interface. If configuring the IP address on multiple units at the same time, the windows software is useful, otherwise it's not that exciting.
I bought three of these for a small network. If you're looking for something more complete or for a bigger installation, i'd go for something else.
These do the job I need them to do for a cheap price in a small setup. They keep PoE Wifi APs powered on and allow multiple VLANs.
A few months on: Hardware seems fairly robust. Mostly a "set and forget" job. You don't want to be logging in and configuring these much, and I haven't had to change the config so far in my environment, they just work.
Usual Netgear quality.
Does it's job.
Management interface is nicely done and easy to navigate.
Only criticism is that some of the ports do not want to let go of the cable plugs when you're trying to remove them. Regardless of pressing the release clip on the plug the sockets seem to hold on to the plugs and require an uncomfortable amount of jiggling to get them to release.
Not a big deal but I'm hoping it doesn't lead to any damage as I will be using these for training sessions and will need to plug and unplug things regularly.
Anyway, other than this it's spot on.
