[tagged | untagged]
In the following example, GigabitEthernet 0/1 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.
Example of Configuring a Trunk Port as a Hybrid Port and Adding it to Stacked VLANs
FTOS(conf)#int gi 0/1
FTOS(conf-if-gi-0/1)#portmode hybrid
FTOS(conf-if-gi-0/1)#switchport
FTOS(conf-if-gi-0/1)#vlan-stack trunk
FTOS(conf-if-gi-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.
debug member
The 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)
Example of Debugging a VLAN and its Ports
FTOS# debug member vlan 603
vlan id : 603
ports : Gi 2/47 (MT), Gi 3/1(MU), Gi 3/25(MT), Gi 3/26(MT), Gi 3/27(MU)
FTOS#debug member port gigabitethernet 2/47
