TL-SG2218 constantly gets reconnected
TL-SG2218 constantly gets reconnected

Model: TL-SG2218  
Hardware Version: V1
Firmware Version: 1.1.3

After upgrading OC200 to 5.4.7, TL-SG2218 starts to act up.

First, I get "Heartbeat missed" a lot from the 2218 which has not been a problem before and nothing has been changed except the firmware for the OC200.

It usually just goes back to "Connected" within a few seconds, but at least once per hour it goes away for long enough that I get notification on my phone that the TL-SG2218 has been reconnected.

Since the firmware for the TL-SG2218 is quite old (20211105) I assume that there might be some issues with the new 5.4.7 in the OC200, but I guess someone has to report it to get it fixed :)

Is there a problem with the switch actually being used?
It is possible that the OC200 has too much data, suggest that you can clear the data.

  @Virgo The switch works perfectly, it's just the constant notifications that it has been reconnected (suggesting it has been disconnected) and the constant "Heartbeat missed" in the admin interface.

If it was the OC200 acting up, I would assume my 9 other devices should also disconnect randomly, not just this switch.

All other devices (2xSG2210MP, 1xSG2008P, 4xEAP245, 2xEAP225-Outdoor) has firmware released in the last 4 months, while the SG2218 has firmware from November 2021.

IIRC controller software 5 required devices to update firmware to be fully compatible. 5.0.29 was released in December of 2021, after the current firmware for the SG2218 was released.

  @Virgo Interesting! That version was not available yesterday! (Funny enough, the version my switch is running was newer than what was available yesterday)

My OC200 told me there was an update for the SG2008P today, running that now.

I assume the update for the 2218 will arrive in the OC200 tomorrow, at the latest. Perhaps everything will be fine then :)

And just minutes later, the update arrived in the OC200 too.

It's been updated, lets hope it solves the problem!

Thanks for the heads up!

Well, it got better, but not resolved.

The switch stills gets heartbeat missed several times per day and I get a notification that the switch has been reconnected :(

  @bollman 

 

You do have a weird problem, have you checked if this problem occurs at regular intervals?
Is there a pattern in the frequency of the error or problem occurring over time?

  @Virgo 

Sorry for long radio silence.

Well, the issue is not resolved. Looking at my LibreNMS I can tell that the switch constantly goes offline, network-wise. There is nothing wrong with the functionality of the switch though, it just seems to loose network connectivity.

This is what it looks like in LibreNMS:

It seems to be up for 5 minutes, then down for at least an hour, then up again for 5 minutes, then down again.

Everytime it gets "up" again, I get a notification on my phone stating that the switch has been reconnected.

  @Virgo 

Issue resolved!

And I'm almost too embarressed to reveal the solution...

I had by misstake assigned the same IP as the 2218 to another device, manually.

blush

So, issue fully resolved, and no problems ever existed, except with the user...
