Dell S4048 need help

Hi


We are having problem setting Dell S4048 switch as basic L2 switch like unmanaged switch, we have it link from our main 10Gbit switch to interface 1/1 and we have interface 1/1-1/48 all in Vlan 100, we have all ports no shutdown and its on however wont allow any forwarding traffic, no internet nothing from interface 1/1 over to all other ports

We have tried everything we found online and cant seem to get it to work, your help is highly appreciated as we have 3 of these switches, all are standalone with just simple drop from the main switch as extension to the main switch

Hello,

here some suggestions:

  • Ensure all ports (1/1-1/48) are correctly assigned to VLAN 100.
  • Ensure all ports are in switchport mode
  • Ensure STP is not blocking any ports

 

Thank you for contacting Dell Technical Support. Your request involves a specific configuration of your Dell S4048 switch. For this type of assistance, you will need to purchase an installation ticket, as we have a dedicated team that handles these advanced configurations.

Please reach out to our customer service for more details on how to proceed with purchasing the installation ticket. We are here to help you resolve the issue as efficiently as possible.

Thank you for your understanding.

Hi, 

 

Based on your logs, it seems that the interfaces are not in VLAN 100. Can you run a tagged TenGigabitEthernet 1/1-1/48 instead of untagged. 

No Events found!
