Ruckus Lennar home configuration help

[mshrivas]

Hi,

I recently moved to a Lennar pre-owned town house (built year 2021). It has ruckus network system (switch + 3 APs) that I've been trying to configure but couldn't do so far. The home internet is provided by AT&T.

Ethernet switch: ICX-7150-C12P

Access point: R510 series

I didn't do any factory reset yet, so just wanted to share the status of switch and APs before performing reset. From unleashed app or web, I cannot find configure.xxx ssd. Please let me know which device needs reset. 

switch:

2nd Floor AP:

 1st floor AP:

 ground floor AP:

Hi @mshrivas 

Greetings!

Thank you for your response and the update.

Let’s look into the switch disconnection issue once you upgrade the Unleashed System.
For now, may I kindly request you to proceed with upgrading your Unleashed system as outlined in my previous message?

Please feel free to let me know if you have any questions or need further clarification.

Thank you once again for your patience and cooperation.

Best regards,

Hi Imran,

I have upgraded the firmware in all 3 APs. Now, please help me with the switch, which shows disconnected.

Thanks,

Hi @mshrivas 

Greetings!!!

Thank you for your recent correspondence and update.

We may need to check some configurations of your RUCKUS ICX-7150-C12P Switch to troubleshoot the Switch connectivity on the Unleashed.

To proceed with troubleshooting the issue, please follow the steps outlined below to access the Command Line Interface (CLI) and provide the necessary command outputs:

1. First, identify the current IP address assigned to the switch ICX-7150-C12P by your local router. You can use an IP scanner tool to easily locate the switch's IP address on your network. Here is a guide on how to perform this using IP Scanner free applications:

2. Once you have identified the IP address of the switch, proceed to access the Command Line Interface (CLI) of the RUCKUS ICX-7150-C12P switch. Here is a guide on how to access the CLI: 

https://community.ruckuswireless.com/t5/RUCKUS-Lennar-Support-Knowledge/How-to-access-the-Command-Li...

If you can access the Command line the prompt should look like below:

ICX7150-C12 Router> OR

ICX7150-C12 Switch>

3. After successfully accessing the CLI, please execute the following commands and provide the outputs:

   enable

   show version

   show flash

   show inline power

   show inline power detail

   show interface brief

Please share the command outputs or screenshots if you encounter any issues or errors during these steps. 

Feel free to reach out if you have any questions or require further assistance.

Thank you for your cooperation and patience.

Hi Imran,

I found the IP address but unable to connect to it using ssh or nc from my macbook. Unfortunately, I don't have a windows m/c to work with. 

ssh admin@192.168.1.xx (xx is actual number but I'm not showing here)

or, ssh super@192.168.1.xx

Unable to negotiate with 192.168.1.xx port 22: no matching key exchange method found. Their offer: diffie-hellman-group14-sha1,diffie-hellman-group1-sha1

I tried to create ssh key using:

mith@Mac ~ ssh-keygen -R 192.168.1.xx

Cannot stat /Users/mith/.ssh/known_hosts: No such file or directory

---

I also tried with telnet

nc 192.168.1.xx 23 

here, there was no error but prompt didn't change, so it didn't work.

Hi @mshrivas 

Greetings!!!

Thank you for the response and the update.

The error message:

"Unable to negotiate with 192.168.1.xx port 22: no matching key exchange method found. Their offer: diffie-hellman-group14-sha1,diffie-hellman-group1-sha1"

means that your macOS SSH client does not accept the ssh-rsa key type by default anymore (due to security deprecation in newer versions of OpenSSH), but the server only offers ssh-rsa.

Fix Options

Option 1: Allow ssh-rsa temporarily via CLI

Add the command: -oHostKeyAlgorithms=+ssh-rsa option when connecting:

ssh -oHostKeyAlgorithms=+ssh-rsa admin@192.168.1.177

Replace ‘admin’ with your actual username.

Option 2: Allow ssh-rsa permanently for this host

Edit or create (if it doesn’t exist) your SSH config file:

nano ~/.ssh/config

Add the following block:

Host 192.168.1.177

   HostKeyAlgorithms +ssh-rsa

   PubkeyAcceptedAlgorithms +ssh-rsa

Save and exit (Ctrl + X, then Y, then Enter).

Try connecting again:

ssh admin@192.168.1.177

Why does this happen?

Newer versions of OpenSSH (8.8 and above) disable ssh-rsa by default due to its dependence on SHA-1, which is considered weak.

Let me know how it goes.

Thank you again for your patience and understanding.
