After doing some reading on SonicPoint configurations, I think we may need to set port 19 to be untagged for vlan 100, and tagged for the other VLANs. interface Gi1/0/19switchport mode trunkswitchport trunk native vlan 100switchport trunk allowed vlan 100,110,120 You could also try the same thing with general mode interface Gi1/0/19switchport mode generalswitchport general allowed vlan 100 untaggedswitchport general pvid 100switchport general allowed vlan 110,120 tagged
At present the company I work has a Cisco SG500X Stacked core, we have replaced some switching with N2048P devices and now we are having trouble getting our SonicWall VLAN Tags across to the port.  On the cisco this is how the port was setup prior to the edge switch change -  !interface gigabitethernet2/1/47 description "Uplink to BS1" spanning-tree portfast switchport trunk allowed vlan add 100,110,120! I have tried various settings on both the Cisco and Dell N2048P switching now and I have not had any success in getting the VLAN tags out to the new switches, including switching the ports both ends to General ports and I have had no success, can someone please help if they have had success on this, also should I ensure that these settings match both ends ? as it hasnt seemed to work so far.  I am from fairly new to networking coming from a cisco background so its a bit of a struggle here.  Thanks,  Rich
