Dell EMC SmartFabric OS10 User Guide Release 10.5.0

Configure untagged access ports

Add untagged access ports to the VXLAN overlay network using either a switch-scoped VLAN or port-scoped VLAN. Only one method is supported.

• To use a switch-scoped VLAN to add untagged member ports to a virtual network:
  1. Assign a VLAN to a virtual network in VLAN Interface mode.

     interface vlan vlan-id
     virtual-network vn-id
     exit

  2. Configure port interfaces as access members of the VLAN in Interface mode.

     interface ethernet node/slot/port[:subport]
     switchport access vlan vlan-id
     exit

     Packets received on the untagged ports transmit over the virtual network.
• To use a port-scoped VLAN to add untagged member ports to a virtual network:
  1. Create a reserved VLAN ID to assign untagged traffic on member interfaces to a virtual network in CONFIGURATION mode. The VLAN ID is used internally for all untagged member interfaces on the switch that belong to virtual networks.

     virtual-network untagged-vlan untagged-vlan-id

  2. Configure port interfaces as trunk members and remove the access VLAN in Interface mode.

     interface ethernet node/slot/port[:subport]
     switchport mode trunk
     no switchport access vlan
     exit

  3. Assign the trunk interfaces as untagged members of the virtual network in VIRTUAL-NETWORK mode. You cannot use the reserved VLAN ID for a legacy VLAN or for tagged traffic on member interfaces of virtual networks.

     virtual-network vn-id
     member-interface ethernet node/slot/port[:subport] untagged
     exit

If at least one untagged member interface is assigned to a virtual network, you cannot delete the reserved untagged VLAN ID. If you reconfigure the reserved untagged VLAN ID, you must either reconfigure all untagged member interfaces in the virtual networks to use the new ID or reload the switch.
