Model: SG2210P  
Hardware Version: V5
Firmware Version: SG2210P(UN)_V5.20_5.20.15 Build 20251031

Hello,

 

I have an Omada SG2210P ( this one https://www.omadanetworks.com/uk/business-networking/omada-switch-access/sg2210p/ ) which is configured in a home network. 

Network-wise it works fine, but after a few days of working I completely lose access to the web interface.

I am trying to access the switch management interface from the same machine/ip that I can access it after the reboot, but after a few days when I try to access the http web interface - the page never loads up in the browser.

SSH works to the point of asking for login and password but after I enter the password, the terminal locks up and does not proceed further.

Only rebooting the switch works.

 

Hardware: 5.20

Firmware: SG2210P(UN)_V5.20_5.20.15 Build 20251031 (latest)

 

I have attached my switch configuration to this thread (removing secrets) - any advice would be much appreciated.

Hi@ivmreg 

Thanks for posting in our business forum.

May I ask the error screenshot when you failed to access the SG2210P via web UI and SSH? Can you provide the network topology for us?

Is this issue happening from the beginning of installation or it was working fine before? Is it happening at random after a few days of normal working?

Hi   @Hank21 

 

Answering your questions:
May I ask the error screenshot when you failed to access the SG2210P via web UI and SSH?

this is a new tab in the browser with switch IP entered. The page loading indicator keeps spinning and page never loads.

 

SSH:

SSH prompt is successful, and after entering login username and proper password, the terminal shell never loads

After a while (1-2 minutes?) I get:

Is this issue happening from the beginning of installation? -

Yes, it happens from the beginning of the installation.

Hi @ivmreg, any chance you have a duplicate IP?

No, I don't think so - the switch's IP is the only one on the network, and it would not explain the fact that during the SSH session the login prompt works, but once the password is entered properly the terminal does not load the shell and just ends up stuck. I suspect some kind of memory leak or a hardware issue. Similar think was manifesting when I was binding this switch to a cloud controller - in which case the switch would just randomly disconnect and remain as such until I reboot it (all the network functions still worked)
