Hi nikog, the configuration on your Dell switch is correct and matches the Cisco setting. You may confirm this by checking MAC addresses learned on port-channel 23:   This command should display MAC addresses in both VLANs. I think the problem is the egress (outgoing) port then as VLAN 100 traffic will get tagged internally in the switch but needs a destination port with "switchport trunk allowed vlan 100" to get these frames out tagged with VLAN 100.

Hello, I am trying to achieve a particular thing:   Every untagged packet should be tagged as VLAN 100 Every tagged packet of VLAN 101 should pass by.   I have tried the following configuration:     In this case the tagged 101 vlan works well. But the untagged traffic does not get tagged as 100. Any suggestions what am I missing?
Configure tagged native vlan and untagged on S4048-ON
