Hi @MYN 

I would recommend you read this thread to have some aspects checked.

1. Check your DST time. Enabled or not. If enabled, please disable it and config it again. After this, your VLAN should be working again.

2. Did you modify any settings recently?

3. Double-check your switch Profile to make sure everything is properly configured.

If your issue persists, please give more details with the diagram, config scheme, and screenshots.

Thank you for your answer.

I will check the DST settings in the omada software controller.

DST has never been activated and from a quick look I saw in the configuration it is disabled.

I haven't made any changes in the last 4 to 5 months.

I will look into sending the information you requested by the end of the week.

Hi @MYN 

I am checking up on you. Is this resolved? How'd it go?

Good morning

I haven't done anything because I had another serious problem and couldn't go to the site to check it out. This weekend I will go and check it and let you know.
Thanks for the question.

Good Evening
Today I came to the site where I have the problem with the SG2008 switch with the vlans. I checked the DST on both the site and the controller and both were disabled.
I enabled them and set them with the correct parameters (week, month, hour) but nothing happened.
The same problem remains, from any vlan I try to ping a specific terminal, I have a request time out.

Whether I ping from the specific terminal or from another terminal I get the same Request time out message. I have four vlans with IP Address 172.168.32.0/24 , 173.168.42.0/24 , 193.168.56.0/24 and 192.168.30.0/24.
The IP Address of the router is 10.10.10.1/24.
The Ip Address of the switch is 10.10.10.2.

My problem is that from the terminal that is on the 172.168.32.0 network I can ping the terminals that are on the 193.168.56.0 network because the printers I have are connected to this network. I can only ping this network no others.
This all happened after the last switch version upgrade to 3.0.8.
I had no problems before the upgrade.

Hi @MYN 

Thanks for posting in our business forum.

If you can post your configuration for the VLAN interface setup, network diagram with the ports and ipconfig, and several ping (to different IPs) results on the PC, I'd appreciate it.

I still gotta double-check this and make sure everything is right.
