Debugging Vlan Stacking - Dell S4048–ON Configuration Manual

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, TenGigabitEthernet 1/1 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.
Dell(conf)#interface tenigabitethernet 1/1
Dell(conf-if-te-1/1)#portmode hybrid
Dell(conf-if-te-1/1)#switchport
Dell(conf-if-te-1/1)#vlan-stack trunk
Dell(conf-if-te-1/1)#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
Example of Debugging a VLAN and its Ports
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)
