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.
INTERFACE VLAN mode
[tagged | untagged]
Example of Configuring a Trunk Port as a Hybrid Port and Adding it to Stacked VLANs
In the following example, the TenGigabitEthernet 0/1 interface is a trunk port that is configured as a
hybrid port and then added to VLAN 100 as untagged VLAN 101 as tagged, and VLAN 103, which is a
stacking VLAN.
Dell(conf)#int te 0/1
Dell(conf-if-te-0/1)#portmode hybrid
Dell(conf-if-te-0/1)#switchport
Dell(conf-if-te-0/1)#vlan-stack trunk
Dell(conf-if-te-0/1)#show config

Debugging VLAN Stacking
To debug VLAN stacking, use the following command.
• Debug the internal state and membership of a VLAN and its ports.
