Ruckus switch ICX 7150 - IP lost after hard reset

[mshrivas]

Hi,

As you asked me to create a new ticket, so here it is. There was a power outrage in my home. After that, the wifi got really slow. Before that, the switch ICX 7150 used to show 'disconnected' in the unleashed dashboard. Also, it didn't have the latest firmware to work with unleased. However, I had ignored it because the wifi was working fine, and I got busy at work.

After the recent power outrage, I went through some topics here and found similar issue raised by members. I tried to fi it myself so I did hard reset on switch because I didn't have login/password credentials and none of the default credentials worked. After the hard reset, the switch has no IP address. I would need your help to configure the switch to its latest firmware, and to be able to connect it in the unleased. I hope after this fix, the wifi should start functioning properly. I have Macbook and no windows laptop to work with.

Thank you,

[mshrivas]

Hi Imran,

The IP address is correct. 192.168.1.xx. I confirmed this with LanScan. 

From mac terminal: 

> ssh 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

We have gone through this step before but I'm unable to make SSH work. There was additional step with SSH (from other thread) but get the same error. 

Can I not work with USBC-Console cable? Why is it so hard to upgrade the switch software?

Hi @mshrivas 

Greetings!

Thank you for your response and the update.

Upgrading the Switch using the tool is a straightforward process.

To proceed, please log in to the Switch through a web browser. You should see the Switch Dashboard (as shown in the screenshot below), which will confirm that you are accessing the correct Switch IP address.

Once logged in, please enable Telnet (refer to the screenshot provided).

After enabling Telnet, try accessing the CLI from your Mac terminal by following the steps below, and share the output of the commands listed in this post:

Open the terminal on your Mac.

Run the following command (replace <ip address of the switch> with the actual Switch IP):

nc <ip address of the switch> 23

Example:
nc 10.0.0.132 23

Please let me know how it goes.

Thank you once again for your patience and cooperation.

Best regards,

Hi,

I followed the steps. Just a correction that TELNET option is under system->management->general, and not under system->general.

Here is the output.

> nc 192.168.1.xx 23

????telnet@ICX7150-C12 Switch>

Thanks,

Hi @mshrivas 
Greetings!

Thank you for your response and the update.

Since you are now able to access the CLI using Telnet, please reset your username and password using the commands below. After completing the reset, wait for a short period and try the upgrade tool again.

enable
configure terminal
device(config)# username super password pass

In this example, the username is super and the password is pass.. (You can use these of your choice)

Next, to ensure proper authentication, please execute the following commands:

device(config)# crypto key generate rsa
device(config)# aaa authentication login default local
device(config)# aaa authentication web-server default local

Please let me know the outcome after performing these steps.

Thank you once again for your patience.

Hi,

@Mac ~ % nc 192.168.1.xx 23

????telnet@ICX7150-C12 Switch>enable

enable

User Name:admin [The User Name was prompted automatically, so gave admin ] 

admin

Password:pass [I gave a password]

telnet@ICX7150-C12 Switch#enable

enable

Incomplete command.

telnet@ICX7150-C12 Switch#configure terminal

configure terminal

telnet@ICX7150-C12 Switch(config)#username admin password pass

username admin password pass [here, I used the same admin/password as above]

telnet@ICX7150-C12 Switch(config)#crypto key generate rsa

crypto key generate rsa

Key already exists. Please zeroize it.

telnet@ICX7150-C12 Switch(config)#aaa authentication login default local

aaa authentication login default local

telnet@ICX7150-C12 Switch(config)#aa authentication web-server default local

aa authentication web-server default local

telnet@ICX7150-C12 Switch(config)#

After this I tried the upgrade tool.

IP: 192.168.1.xx

user name: admin

password: xxx

I get error that it is unable to reach device
