Usage Information

Prior to using this command, to place the interface in Layer 2 mode, use the switchport command.

To remove the trunk port designation, first remove the port (using the no member interface command) from all stackable VLAN-enabled VLANs.

In Example 1, a VLAN-Stack trunk port is configured and then made part of a single-tagged VLAN.

In Example 2, the tag protocol identifier (TPID) is set to 88A8. The Te 3/10 port is configured to act as a VLAN-Stack access port; the Te 5/1 port acts as a VLAN-Stack trunk port, switching stackable VLAN traffic for VLAN 10, while also switching untagged traffic for VLAN 30 and tagged traffic for VLAN 40. (To allow VLAN 30 traffic, you need the native VLAN feature. Use the portmode hybrid command. For more information, see the portmode hybrid command.

Example 1
DellEMC(conf-if-te-1/42)# switchport
DellEMC(conf-if-te-1/42)# vlan-stack trunk
DellEMC(conf-if-te-1/42)# show config

DellEMC(conf-if-vl-100-stack)# interface vlan 20

Example 2
DellEMC(config)# vlan-stack protocol-type 88A8
DellEMC(config)# interface TenGigabitethernet 3/10
DellEMC(conf-if-te-3/10)# no shutdown
DellEMC(conf-if-te-3/10)# switchport
DellEMC(conf-if-te-3/10)# vlan-stack access
DellEMC(conf-if-te-3/10)# exit

DellEMC(config)# interface TenGigabitethernet 5/1
DellEMC(conf-if-te-5/1)# no shutdown
DellEMC(conf-if-te-5/1)# portmode hybrid
DellEMC(conf-if-te-5/1)# switchport
DellEMC(conf-if-te-5/1)# vlan-stack trunk
DellEMC(conf-if-te-5/1)# exit

DellEMC(config)# interface vlan 10
DellEMC(conf-if-vlan)# vlan-stack compatible
DellEMC(conf-if-vlan)# member Te 4/1, Te 3/10, TenGi 5/1
DellEMC(conf-if-vlan)# exit

DellEMC(config)# interface vlan 30
DellEMC(conf-if-vlan)# untagged TenGi 5/1
DellEMC(conf-if-vlan)# exit

DellEMC(config)# interface vlan 40
DellEMC(conf-if-vlan)# tagged TenGi 5/1
DellEMC(conf-if-vlan)# exit
