how to go back to version 1.1.50.39 firmware from version 2.0.0.1 Insight-ready firmware
Hi, did someone has been able to go back to firmware version image 1.1.50.39 on a GS724TPv2 that has been upgraded to version 2.0.0.2 ? My company bought a GS724TPv2 managed switch for a PoC and...
Welcome to Netgear community, SSDP traffic is designed to support Insight-enable on v2.0.1.2, and no option to disable it on GUI, multicast less than 10 packets per sec, so it's harmless when device working in standalone or Cloud mode, it shouldn't cause device flooding or reload.do you see anything else broken beside uplink port traffic light LED flash?
Can I know your topology in more detail? how many other devices are connected?
Internet -- FW -- GS724TPv2 --any additional devices?
v1.1.50.39 is transition image from non-insight support (v1.1.x.x) to Insight-enable image (v2.0.x.x), upgrade path should be v1.1.x.x -> v1.1.50.39 -> v2.0.x.x, however downgrade from v2.0.x.x to v1.1.50.39 is restricted by design, there is another downgrade transition image to support downgrade from Insight-enable to non-insight support image, but it's for internal usage and not posting officially.
Hi Bruce,
Thanks for your answer. Sorry for the delay in my reply. Several things fell on my plate last week...
With firmware 1.1.1.29, to experiment VLANs and trunking were configured with some servers to evaluate switch's capabilities during the PoC. Things went well. Then the ill-advised "firmware updates too far" were applied. without the possibility to go back to 1.1.1.29. Soon after that, security team who manage the firewall brought to my attention the GS724TPv2 switch was poking the firewall other zones's interfaces with SSDP traffic...
Network topology is also simple (see diagram below). The switch was located in our "Purple zone" (aka Lab) zone behind a firewall. The firewall controls traffic to others zones and outside. All traffic being dropped between purple zone and everything else. Links are all at 1Gbps on Cat6 cables. No IPv6.
Under firmware 2.0.1.2, the switch has been reverted to its factory/default configuration. Only NTP and switch's static IP address parameters have been modified. As I wrote previously, the switch has been pulled out from the Lab zone and is now on the side line as we are investigating flapping events and its reboots needs and while the team is deliberating what we'll do next.
Kinds Regards
Thanks for your feedback, under firewall device, is there any other switch device connected to GS724TPv2? Before pulled it out from the Lab zone, did you see anything broken on GS724TPv2 beside LED traffic flash? e.g. port down, system hang or reload, or port flapping?
Hi Bruce,
nothing's physically broken on the enclosure. switch is securely racked in the server room. There is a GS308E switch physically located in the office area, that is connected to the GS724TPv2. Port flapping occurs from time to time (each 36-48h) , usual sign of failure is when all front LEDs start flashing at the same time. When this happen, a hard reboot resolve the problem... for another 36-48h...
My patience is running thin. I'm looking to replace the switch.
