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.INTERFACE VLAN mode[tagged | untagged]Example of Configuring a Trunk Port as a Hybrid Port and Adding it to Stacked VLANsIn the following example, TenGigabitEthernet 1/1 is a trunk port that is configured as a hybrid port and then added to VLAN 100 asuntagged VLAN 101 as tagged, and VLAN 103, which is a stacking VLAN.Dell(conf)#interface tenigabitethernet 1/1Dell(conf-if-te-1/1)#portmode hybridDell(conf-if-te-1/1)#switchportDell(conf-if-te-1/1)#vlan-stack trunkDell(conf-if-te-1/1)#show config!interface TenGigabitEthernet 1/1no ip addressportmode hybridswitchportvlan-stack trunkshutdownDell(conf-if-te-1/1)#interface vlan 100Dell(conf-if-vl-100)#untagged tengigabitethernet 1/1Dell(conf-if-vl-100)#interface vlan 101Dell(conf-if-vl-101)#tagged tengigabitethernet 1/1Dell(conf-if-vl-101)#interface vlan 103Dell(conf-if-vl-103)#vlan-stack compatibleDell(conf-if-vl-103-stack)#member tengigabitethernet 1/1Dell(conf-if-vl-103-stack)#do show vlanCodes: * - Default VLAN, G - GVRP VLANsQ: U - Untagged, T - Taggedx - Dot1x untagged, X - Dot1x taggedG - GVRP tagged, M - Vlan-stackNUM Status Description Q Ports* 1 Inactive100 Inactive U Te 1/1101 Inactive T Te 1/1103 Inactive M Te 1/1Debugging VLAN StackingTo debug VLAN stacking, use the following command.• Debug the internal state and membership of a VLAN and its ports.debug memberExample of Debugging a VLAN and its PortsThe port notations are as follows:• MT — stacked trunk• MU — stacked access port• T — 802.1Q trunk port• U — 802.1Q access port• NU — Native VLAN (untagged)Dell# debug member vlan 603vlan id : 603ports : Te 2/4 (MT), Te 3/1(MU), Te 3/25(MT), Te 3/26(MT), Te 3/27(MU)Service Provider Bridging 839
