Model: OC200  
Hardware Version: V1
Firmware Version:

Hi, 

 

I configured my network with OC200

 

ER7602

SG2218P

SG3428

 

and I'm not getting an IP address from VLAN internal DHCP.

For MGMT VLAN its working. For all other VLANs not.   Example: Heimnetz VLAN:

 

 

 

 

 

I can unplug/plug the cable and try to renew the IP, but it doen't get an IP. Its not working for no network.

Thank you both for your replys.

I was not able to solve it, so I decided to set everything up freshly. Afterwards it worked.

Luckily it is only a test setup right now, but if this would happen in live environment that would be a disaster.

 

Hopefully this does not happen again.

 

 

I have change a little thing in my current design:

- Before the router was connected to the 28-port switch which was connected via a aggregated link (2x1000G SFP) to the 18-port switch where the OC200 and clients where connected to.
- Now the router is also connected to the 18-port switch directly.

Maybe there was a problem with the aggregation... I don't know. Will do further tests...

Did you tag the trunk port on the switch for that VLAN?

Hi @SebastianH 

Thanks for posting in our business forum.

Like what's being said above, have you double-checked if this VLAN is through from the router to the switch and then to the client?

Did you miss this VLAN in the port profile config anywhere in this setup?

That could be the only reason when you fiddle with the port profile. By default, the "All" profile, I believe it works perfectly. Right? If your answer is yes, then somewhere in the config you misconfigured the VLAN.

Would need a diagram of the setup. Or I am not able to troubleshoot. Just tell you that your VLAN is not right.
