Hi folks, please help me regain a little sanity, and reduce further hair loss! I have a case open with Netgear about this but thought it worth asking here in case anyone has seen anything similar. We've just replaced a single core switch with two, split over two sites and linked via 10Gb fibre. There is an M5300-52G3 and an M5300-28GF3 linked as a remote stack via 10Gb fibre and managed as a single stack. Each has a number of GS7xxTP PoE switches attached for wifi access and some GS748Ts for wired access. The ports that the access points plug into on the 748TPs are configured as tagged for VLANS 10, 20, 24, 28, 32, untagged for VLAN 3 and have a PVID of 3. The 748TP trunks back to the stack have all VLANS tagged. On the stack trunk ports connected to the 748TPs the VLANS are all set as tagged.

It is plugged in to a port on the 52G3 that is a member of VLAN 10 only and has a PVID of 10. The switch stack is configured for DHCP relay and is using static routing between all of the VLANS mentioned so far. The issue I'm having is that everything on the PSK authenticated networks and also on the RADIUS authenticated parts of VLAN 10 is fine and dandy but on VLANs 20 and 24 a lot of RADIUS traffic seems to be going missing. Access points connected via the 52G3 mostly seem to be working okay (95% of clients authenticate successfully) but RADIUS connections from access points connected via the 28GF3 don't seem to be making it over the stack link to the server; most but not all fail. Consequently almost nobody can connect to the correct wifi on that site. Bizarrely, a few RADIUS requests do manage to make it across so it's unlikely to be a misconfiguration, else none would make it. We're currently working around the issue by attaching staff to a less secure wifi VLAN that uses PSK. Our previous core switch, a forerunner of the M5300-52G3 called GSM7352Sv1, had exactly the same configuration apart from stacking and worked flawlessly so I'm convinced that the server and wifi side of things is not at fault since nothing has changed on them. We replaced the single core switch to reduce the number of fibre runs that traveled a long way over a main road and back again and terminated most of the fibre on the M5300-28GF3. Anyone got any ideas what might be going on here? I'm completely stumped!

(I have posted the below under "Enterprise Software" as well - sorry if this is bad practice but the below is relevant in both!) Hello everyone, We currently are having issues with multicasting. We have SCCM 2012 installed and are imaging computers. Our problem is that when multicasting it takes ages to open a session and to download the image WIM file. Also, when PXE booting the computers once we have about 10 computers imaging it takes ages to contact DHCP for an IP address. Also, it will struggle to obtain an IP address when the computer has booted into WinPE - by struggle I mean it sometimes does not get an IP address before it times out and bombs out!. If we keep retrying it will eventually work - imaging is still very slow. When we open Task Manager whilst the computer is downloading the image the network utilisation does not get anywhere above 1.50%!!! Our network consists of Netgear GS724TP and GSM7224 switches. We have a GSM7224 switch as our core switch in the server room. We also have a couple of HP Procurve switches in the server rack that are part of our high availability server virtualisation setup. Our network is flat - no vLANs. All switch links are connected at 1GB. We have checked the switches to the best of our knowledge and they all have IGMP enabled and spanning tree is set to RSTP. I hope the above makes sense - we can only think that the issue is down to some settings on the switches. Thanks in advance! J.Worth.

Hi, We have just moved our Internet connection from our LEA to Virgin Media but have encountered a problem. When we connect our network to Virgin Media's co-managed firewall (which is on site), the firewall reports a lot of errors on the 3 interfaces connected to our network but 0 errors on the interface connected to their router. We have connected a laptop direct to the firewall (in its own VLAN) and there are no errors. We've changed the patch leads, disconnected everything else from the switch (just leaving the firewall and laptop connected to it) and plugged the laptop and firewall into a different switch but cannot work out what is causing the errors. Virgin Media are saying that their firewall is configured correctly and because the direct connection to the laptop works without errors it must be our network. We have also tried turning off auto negotiation and setting the ports to 100Mbps Full Duplex which didn't seem to make a difference. We want to keep the ports running at 1Gbps however as our Internet connection is 200Mbps (The Netgear switch won't let us force 1000Mbps Full Duplex). The firewall is a Palo Alto PA2020, our switch is a Netgear GSM7328S v2 (Layer 3) and we have a Meru MC1500 wireless controller. We have 4 VLANS (lets just call them 1, 2, 3 and 4 to make it easier). Firewall Port: 2 Switch Port: 1 VLAN Membership: 1/T, 3/T PVID: 1 Firewall Port: 3 Switch Port: 2 VLAN Membership: 2/T PVID: 2 Firewall Port: 4 MERU Port: 3 VLAN Membership: 4/T PVID: 4 The only configurations I have made on our switch is its IP, NTP, IGMP Snooping + Querier, 1 x LAG and VLANS + Memberships. Routing is disabled and so is STP. Any help/suggestions would be greatly appreciated. Thanks in advance, Dan

Hi Guys and Girls. We are looking at upgrading our backbone and server room switches from Netgear GS724TS to something with a bit more throughput such as HP 1910-48G showing 104Gbs. Can anyone recommend this switch or another switch that would suite the bill. We would like high throughput, 48 x 1GB Copper ports and room for 4 SPF modules. We can get the 1910 for £350 and the modules for £135 so something similar price would be great but we can stretch to £1,000 for the 1 switch and 2 modules if need be. Thanks in advance for recommendations or suggestions, Thanks, Tom

Evening guys, We've just received our 4 free GBIC modules from Netgear - part of a promotion that was running the other month. So we plugged one into our new Netgear switch - a GS724TS and connected it to the network - it didn't work. So we plugged it into our new 48 port switch - GS748TS - and it didn't work. So we tried the three others and not one of them worked. So we moved a DLink GBIC module from a DLink switch and plugged it in - ahh it worked. Has anyone got any idea what we need to do for the Netgear ones to work? At the moment they are just dead. Do the switches need to be turned off and then on with the gbic modules installed? I assumed they were hot pluggable like the DLink ones are. Any help appreciated, Gareth

It would be great if somebody knows a way to recover from this: A failed firmware upgrade of a GSM7328S has ended up with the switch constantly outputting garbage characters over the serial console. The switch was upgraded directly from 5.0.1.8 to 8.0.3.11. Yes, I should've known, but this was done in a hurry. The update to 8.0.3.11 went fine, but after reboot the switch stops at the Boot code screen: 1 - Start operational code. 2 - Start Boot Menu. Starting the operational code fails. From here we tried loading an older firmware version (6.0.0.15) over XMODEM. This fails with the following: "ERROR: Code image size of 1 bytes is invalid" The last step in the bricking of this device was using the Netgear Serial Recovery Tool. The tool ran fine and updated to 7.2.0.5. However, the tests done after upgrade failed. A reboot now results in the unit outputting a few characters of pure garbage at 1hz (once / sec) across the serial port. Changing baud rates over the serial connection doesn't help - the characters are still garbage. If anyone can help with this I'm eternally grateful

Hi, We have got one of these not being used, a cabling contractor supplied it last year, but the LEA weren;t happy and gave us a Cisco switch. It has sat turned off in our cabinet for about 10 months, thought it was about time I got rid of it. Worked fine when I turned it on this morning and connected a few machines to it. Complete with power lead and front/side brackets. Might also be on Ebay as well (will update with link). Any offers, maybe £50, plus £10 postage? ? More info: Answer

We've recently upgraded to UniFi across school so no longer need our old Netgear switches. We have the following 24 Port Netgear switches: 1 x JGS524 v1 6 x GS724T (1 x V3 and 5 x V4) 2 x M4100-26G Plus 2 x AGM731F Netgear Fibre modules (never used) 1 x LevelOne GSW2457 24 port switch I'd ideally like to get rid of the whole lot in one go. Any sensible offer accepted.

OK, here's the requirement. I have a Netgear GS748T switch in one cabinet and an HP Procurve 1810G switch in another - I want to setup 2 VLANs - one for the academic network and one for accounts. In addition I have a Fortigate 80C which is used as a perimeter UTM device but can also act as an L3 router. I need the accounts PCs which are connected to the Procurve to be able to connect to the academic VLAN but the academic PCs (connected to the Netgear switch) not to be able to access the Accounts VLAN. I'm assuming that I can use the Fortigate as an L3 router to enable inter VLAN routing but I'm unsure where to start, or even if it's possible/desirable to have HP and Netgear setup in this way. Can anyone give me some pointers or basic setup instructions? Thanks in advance.

Hi, We have 2 closets. 1 with users and the servers, and one with only users. We are upgrading all of our swtiches to gigabit. We have decided on the netgear gs748ts. We want to run fiber, but I have no idea wear to start. How much can we get, what connectors etc. Can anyone help?

Hi please can I have some advice. We are currently running our network on FS726T netgear switch. The netgear website says it is suitable for small to medium sized business. Our school currently has 1700 users and 600pc/laptops, would you consider this to be a medium sized business. Do you think we should upgrade to layer 2 switches? Thanks

Hi, Does anyone know if things like trunks, vlans and qos are compatible between procurve and netgear switches? possibly a daft question, but i maybe purchasing a mixture of procurve and netgear in the very near future. thanks

Hello everyone, I know that there are 3 versions of STP - STP, RSTP and MSTP. We have a mixture of Netgear GSM7224, GS724TP, and GS748T. My question is, how do we setup STP for our network? We have a flat network. Should we enable RSTP for switches that have client machines connected (edge switches) to them and then use the ordinary STP version for our core switches? Thanks in advance!
