Network Loops causing our devices to freeze
We’re experiencing a lot of NetGear Prosafe switches freezing, and we’re forced to do a reboot on all switches twice a week as we cannot trace where the issue is coming from. We are looking on a pos...

Also, does that mean that all the switches provided are not managed switches, that's why the CPU and Memory usage cannot be viewed via NMS300?
Afraid, yes - exactly explained in the older thread already, too.
STP or RSTP are your new friends.
Any devices or components on your network potentially playing "bad" - like wireless bridges, media players (e.g. SONOS), sophisticated storage and App server systems with software defined networking (like QNAP QTS)?
Hello schumaku,
Thanks for the response.
Just a quick follow thru questions below.
1. Do you consider satellite dishes as wireless bridge?
2. Will it have any service impact if you enable STP / RSTP on the network immediately? The switches are connected more like star topology.
3. Any way we can setup CPU and memory usage for the devices stated on my initial post?

Anything that can cause a potential loop - especially when there is some redundancy in the play.

If available all over go for RSTP. You will find that only one part of your star architecture be forced disconnectred worst case - instead of knowcking the complete system down. This should allow some localized troubleshooting later on.

The moment when CPU and/or memory usage would explode (if it does at all - it's more likely traffic on links, typically broadcast ...) will be the moment you loose the in-band management access to the switches anyway. Not sure why you are so keen for it.
WHello schumaku
Thank you for the answer.
We are keen to know the CPU and Memory usage for each device since we would like to know which device we should reboot instead of rebooting all devices when the network goes down, because we don't know which switch freeze.
Is this possible on those switches provided?
