36 TopicsM4300-52G-PoE Stuck in U-Boot - ERROR: can't get kernel image!
Hi Everyone, This is my first post to the Community. I am posting this procedure for those poor souls out there, which like me have experienced this issue (there are several similar posting on this forum with no solution). It took me several valuable hours to get this. This is the procedure to get your Netgear Managed Switch up and running to be able to do detailed diagnostics (in my case it turned out the flash partitions for the 2 image packages were toasted) 1. Download a Firmware Image file for the M4300 from the Netgear Support website 2. Extract the Firmware Image file from the downloaded Zip file to your PC/Laptop 3. Ensure you have a TFTP Server installed on your PC/Laptop 4. Connect to the M4300 via a Console cable 5. Power on the M4300 6. let all the Errors display and wait for the U-Boot "m4300r2>" prompt to appear 7. enter "printenv" and check that the following Environment variables have the following values : - ipaddr=192.168.0.10 - serverip=192.168.0.100 8. if values don't match above, enter the following commands - "setenv ipaddr 192.168.0.10" - "setenv netmask 255.255.255.0" - "setenv gatewayip 192.168.0.1" - "setenv serverip 192.168.0.100" 9. Set your PC/Laptop Ethernet interface IP to 192.168.0.100 10. Connect PC/Laptop Ethernet interface to the OOB Ethernet port on the front of the M4300 11. Start your TFTP Server on your PC/Laptop and set the root directory to the location of the extracted Firmware Image file 12. Enter the command "run bootargs_set" 13. Enter the command "tftpboot 0x62000000 m4300v12.0.13.8.stk" [Note: I used ver 12.0.13.8, use whatever filename is in the Firmware package] 14. Wait for the Firmware to upload to the M4300 15. Do NOT disconnect the Ethernet connection 16. Enter the command "bootm 0x62000074#ranger2" 17. The M4300 will begin to load the Application file and error again -- don't panick 18. The M4300 will again automatically load the Firmware Image file from the TFTP Server 19. Then Finally, at last, the M4300 will boot to a fully operational condition 20. Optional: Enter the commands "#delete 1 image1" and/or "#delete 1 image2" 21. Optional: Enter the commands "copy tftp://192.168.0.100/m4300v12.0.13.8.stk image1" and/or "copy tftp://192.168.0.100/m4300v12.0.13.8.stk image2" 22. Optional: Enter the commands "boot system 1 image1" and/or "boot system 1 image2" In my case the last 3 commands all failed as the Flash was obviously damaged :( PS: Why Netgear does not publish recovery instructions for the M4300 series is baffling to me, given there are many request on this forum and others requesting it . . . . anyway thought I would share . . . . hope it works out for you2.4KViews3likes1CommentAV VLAN uplink to public manage switch
Hi All: At our educational facility we are redesigning an existing 2 x room AV system with "cross-room" Audio Visual broadcast connectivity using Crestron Digital Media architechture Each room has a dedicated Crestron DMPS-4K-350-C + DMPS-4K-250-C units with with TV displays, Microphones and Camera's. We have a new Audio Visual private VLAN link between 2 x rooms using core Netgear AV Line switches being programmed for the Crestron Graphic User Interface control in each space. Netgear M4250-9G1F-PoE+ network switch (smaller room 1) + Netgear M4250-26G4F-PoE+ (GSM4230P (larger room 2) My question is for how we can securely manage the AV endpoints inside the private AV VLAN? Crestron virtual X-panel touch screen control is needed + two DMPS hardware units, Biamp audio processors; we need IP control into this new private AV-VLAN from our existing public managed Switch local subnet. I would like to create an ethernet patch uplink from the core Netgear M4250-26G4F-POE (same AV system rack as our Crestron Managed switch) into our local managed public subnet switch which is a Crestron CEN-SW-POE16 Any thoughts on the best way to configure this would be appreciated. Thank you23Views0likes1CommentDoes GS728TPPv2 have a limit on number of mac addresses in a mac address-based VLAN?
I'm looking for a switch with POE and mac address-based VLAN capabilities and came across the GS728TPPv2. I want to put my smart home devices in a separate VLAN using the mac address-based VLAN feature. Is there a limitation on the number of mac addresses that I can assign to a VLAN via a static table? ThanksCan't login to M4300 since 12.0.19.15 firmware update
Hello, I just updated two switches M4300-28-POE+ to 12.0.19.15. I go to the IP address of the switch It has the AV UI login and the Main UI Login - I can log into the AV UI login but NOT the Main UI login which is the one I need. It goes to this site can't be reached. I reload no luck. I rebooted the switches - no luck. I tried another browser - no luck. I tried incognito mode, no luck. There is no firewall or antivirus blocking it. It worked fine until the firmware update. Short of resetting the switch to factory defaults which probably won't fix it, any suggestions other than applying an older firmware?90Views0likes1CommentReplacements for obsolete SNMP OIDs for M4350-8X8F
I'm using SNMP to query some properties of a M4350-8X8F switch. One of the properties I need is the current authenticator PAE state for a give interface. I see there is an OID agentDot1xClientAuthPAEstate in the NETGEAR-DOT1X-ADVANCED-FEATURES-MIB that seems to do what I need, but its status is obsolete and no alternatives are listed. I would also like to query the current Guest VLAN ID of a given port. The OID agentDot1xGuestVlanId in the same MIB looks promising, but it is also obsolete and I can't find the alternate OID it is referencing agentAuthMgrNoResponseVlanId in any of the MIB files. Does anyone know which OIDs I can use to get these properties, or if it is simply not possible to do this anymore with SNMP?19Views0likes0CommentsInquiry: 24×1 Gbps Copper + 2x10G Copper & 4×10 G SFP+ Uplink - Layer‑3 Switch (non‑PoE)
Hello, I am looking for a Layer‑3 switch from NETGEAR with the following specifications: 24 ports of 1 Gbps copper RJ‑45 (non‑PoE) 2 ports of 10 Gbps copper & 4 ports of 10 Gbps SFP+ uplinks Full Layer‑3 routing features (static routing, inter‑VLAN routing, etc.) I previously used the GSM4328S, but I understand that it has been declared End‑of‑Life (EoL). Could you please advise if NETGEAR currently offers a model that matches or closely matches the above requirements? If there is none, I’d appreciate suggestions for the closest alternative.81Views1like4CommentsEngage Onboarding Issue
We have 15 M4250 switches running our AV network. Recently, we realized two of those switches were assigned the same IP. Because of this, only one of the devices was showing on the Engage Dashboard. We did a hard reset on one of the switches (the one that was showing) so that we could assign it a new IP. Now the one switch that I reset will not show in Engage. I went through the Main UI to assign it a new IP address and when entering that IP into "Add Device" on Engage, I'm met with the message that the "device is already onboarded". How can I clear it from onboarding so I can set it up as a new device? Or at the very least, get it to show in Engage?99Views0likes4CommentsM4300 SNMP zabbix problem
Dear All! I tried to start to monitor my netgear switches, and on the server i choosed the built in netgate template. Works fine expected two things, the psu and the fan recognize is false, found a few threads about this but no solution. At mapping i see this: The switch default state is two, so thats noot good, and if i try to snmpwalk th oid i get only 1 and 2 for value if im doing it good. The fan state is fan 0: 1.3.6.1.4.1.4526.10.43.1.6.1.3.1.0 and gets 2 what is fault in the value, but cannot figure out what is the correct value. Now to solve the problem in the mapping i switch operational and failed value, and in the macro set the fault to 1, now its reports okay but im not sure its 100% will work when i have a fan error. PSU the problem i have is the psu0 has problem and i dont know why.195Views0likes3Comments(M4300) Couldn't connect to emWeb, socket failed, 2 No such file or directory
