Ruckus ICX7150-C12 Switch is frequently dropping internet connection

darkcoffee243 — Thu, 10 Dec 2020 02:32:00 GMT

I own a Lennar home that comes with a pre-installed Ruckus ICX7150-C12. I never had issues with the internet connection from the switch until a Spectrum agent came over to my house to replace their modem with another one. Since then, any connection via the ruckus switch, either through ethernet or the unleash wireless access points, has been unstable. Unstable, meaning my browser failing to find the DNS server, videos not loading, etc. My router, a TP-link AC1750, is connected in between the ruckus switch and modem and has no problems connecting to the internet. I've tried resetting the Ruckus Switch via powercycling and factory resetting the TP-link router, but the issues still persist.

I also noticed that the Spectrum representative rearranged my cat6 cables that are connected from the router to the switch. I don't know why he did this, or what else he changed. Currently, the configurations are this: The modem's ethernet cable is connected to the router, and the router's ethernet cable is connected to one of the 10 numbers ethernet ports.

In short, the ruckus switch's connection to my internet has been poor ever since my modem was swapped out for another one. Resetting all three devices (switch, router, modem) doesn't seem to have helped.

Hello,

Understand your situation, but Its difficult to predict what the issue could be. Since it all started after the replacement of modem, Pls check any settings got changed or DNS address on router (primary/secondary) which can cause similar issues.

If you have access to switch (telnet/console), You may also open a Tac case so one of our tech can look into the problem.

Is it the same irrespective of connecting to wireless or wired ?

Thanks

Jijo

Thanks for the reply. I had already opened a case with support and basically what had happened was that the switch converted to router mode, which might have happened after the spectrum techincian powered off the switch. The ruckus engineer switched it back to switch mode and all is good for now.

Glad to hear that, You can also set the system to always boot from primary or secondary based on where the switch image is loaded.

Here is the reference link, You may also ask the ruckus tech for config assistance.

Hi I just wanted to provide concrete answers on how to determine if your switch is in router mode or switch mode My symptoms:

Intermittent traffic drops on ruckus network

Normal traffic on ISP gateway

DHCP list on ISP gateway's web GUI showed ICX7150-C12 Router

dylan_chun_wong — Sat, 12 Dec 2020 06:02:02 GMT

Now to fix it... Write down the IP address that the device was assigned. In my case it was 192.168.1.89.

Open a telnet session to the switch. Using bash on Windows worked, or perhaps putty bu the gist is 'telnet 192.168.1.89', I wasn't able to get the web GUI to work

NOTE: you need to be connected to your ISP gateway or something that's not the ruckus AP because for some reason this doesn't work

'show flash'

Validate that you see an image with SPS in the primary, in my case it was SPS in the pri (primary) and SPR (router) in tehe sec (secondary)

'enable'

Enter EXEC mode

'boot system flash primary'

Tell it to boot to the primary image

Agree to boot to the primary

At this point you should get kicked off the telnet session and you should see it change to 'ICX7150-C12 Switch' in the DHCP list and everything should work as normal. I hope this helps other people who encountered this during WFH and banged their heads.

In addition I used these commands to backup the current images in flash, then copy my switch image:

enable
show flash
1. write down the names of the images in parens
copy flash disk0 primary sps08080d.bin
copy flash disk0 secondary spr08080d.bin
copy flash flash secondary

This was very helpful Dylan

In addition to the above commands suggested by Dylan, the Ruckus Support suggested the following.

1. Once you are in the telnet session

2. Switch to EXEC mode using the ENable command

3. "show int b" (this command will show all active ports

I have the same issue how do I fix it?

Juan, you have not provide enough information on what the issue is and what steps you have taken to determine it that so far. I am going to assume that you are very familiar and comfortable with network troubleshooting..

Dylan provides very detailed steps on how to reset your ICX7150 from router mode back to switch mode. Are you familiar on how to use Telnet or similar software to log into the switch? If not, you should open a Support case with Ruckus. Or better still, call your Lennar Home warranty department and work through them.

Hi - I am some what technical but don't know how to use TELNET - this has been frustrated as Lennar's reply is they are not a technology company and can not support anything from their SMART HOME SELLING IDEAS

my current situation is the following - if I connect to the ATT router via cat5/6 cable or wifi I have no issues

if I connect via the Rockus devices - can stream, cant use VOIP, and internet pages timeout - via wifi or via hardwire

on my amazon firestick if I use VPN then I can get a slow stream - if VPN is not active Netflix, Disney plus or any other streaming service is useless (via WIFI on rockus)

Your best bet would be to open a case with Ruckus. They are very helpful. They will take control of your laptop and then troubleshoot the ICX switch.

I did open the ticket - i hope it helps - I can see many posts regarding issues with Rockus systems from purchasing for new hardware from other brands

Re: Ruckus ICX7150-C12 Switch is frequently dropping internet connection

ravi_ramakrishn — Wed, 30 Jun 2021 21:14:30 GMT

Juan, I do not work or represent Ruckus. All I can tell you that it is solid hardware and is "enterprise-class" (used in large campus like organizations). My opinion is that Lennar sub-contractors do not do a good job in the cabling installation, hence the issues.

My suggestion is for you to wait for the engineer to respond, allow them to fix it and if it does not, then it is decision time.

@dylan_chun_wong Your instructions were exceptional. I have a new problem. After this morning's brief power outage, my switch reverted to the Router mode. I have tried restoring the PRI config and it does not switch back. Am I doing something wrong?

jared_hughes — Sat, 21 Aug 2021 04:05:27 GMT

I know this thread is a bit old but I just came across this problem and am having trouble getting connected to a telnet or ssh connected to the switch. It all makes sense on the page, I just cant get into the client at all. Any tips? My setup is ISP Modem - > ISP Router - > Ruckus Switch.

We recently had a large power outage and had been getting massive DNS issues and had the ISP come out and replace our router but then it started having issues again with the wireless.

@ravi_ramakrishnan

Did you ever figure this out? I am having the same issues

Re: Ruckus ICX7150-C12 Switch is frequently dropping internet connection

ravi_ramakrishn — Sat, 21 Aug 2021 12:50:57 GMT

@jared_hughes I had to call Ruckus Support. They were awesome. It appears that my PRI config file was bad. They were able to rebuild it and then ensured that both my PRI and SEC configs were the same. So, now, if a power flick caused it change both are the configured to keep it in SWITCH mode. The switch is unlikely to be used as router in a Lennar Home.
