In Figure 44-4 GigabitEthernet 0/1 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.

Debug VLAN Stacking
To debug the internal state and membership of a VLAN and its ports, use the debug member command, as
shown in Figure 44-5. The port notations in Figure 44-5 are as follows:
• MT — stacked trunk
• MU — stacked access port
• T— 802.1Q trunk port
• U— 802.1Q access port
• NU— Native VLAN (untagged)
2 Add the port to a 802.1Q VLAN as tagged or untagged. [tagged | untagged] INTERFACE VLAN
