Network Loop Netgear

Locked

Tags: Community, Hardware, Networking

Hi All,

I recently Was working with Cisco Meraki support to troubleshoot a problem AP. We discovered it’s gonna need to be replaced. However while looking into it, we ran a packet capture on the switch the ap is connected to and we noticed that there are thousands of frames being sent by netgear with RLDP loop detection packets. I had to install probably 150 netgear switches in the building because they went to VOIP for their phone system.

If I look at the capture in Wireshark I see, abbreviated:
Source – Netgear
Protocol – RLDP
Info – Network Loop Detection

Is this saying that a loop is being detected on the network, or that a loop is being looked for? I checked the manual for the switch and “Loop Detection” is from what I read disabled by default. There is also a Broadcast Filtering, trying to determine the difference. There has been complains about latency in the building. I don’t know that this would factor in, however I wanted to ask the community.

Given what this loop is.

I have never found software to be the answer. I’ve had to get out to the network and find the rogue or incorrect connection.

I can agree with that. The issue I’m facing is that there are so many devices and I’m also trying to figure out if it’s a config issue. Never had to deal with something like this. Hoping someone else has seen this before. I have a case open with Netgear as well.
