Configuring Dell Networking OS Options for Trunk Ports 802.1ad trunk ports may also be tagged members of a VLAN so that it can carry single and double-tagged traffic. You can enable trunk ports to carry untagged, single-tagged, and double-tagged VLAN traffic by making the trunk port a hybrid port. To configure trunk ports, use the following commands. 1 Configure a trunk port to carry untagged, single-tagged, and double-tagged traffic by making it a hybrid port. INTERFACE mode portmode hybrid NOTE: You can add a trunk port to an 802.1Q VLAN as well as a Stacking VLAN only when the TPID 0x8100. 2 Add the port to a 802.1Q VLAN as tagged or untagged.
