White Papers

To remove the trunk port designation, first remove the port (using the no member interface
command) from all stackable VLAN-enabled VLANs.
Starting with the Dell Networking OS version 7.8.1.0, a VLAN-Stack trunk port is also allowed to be
configured as a tagged port and as an untagged port for single-tagged VLANs. When the VLAN-Stack
trunk port is also a member of an untagged VLAN, the port must be in Hybrid mode. Refer to portmode
hybrid.
In the first example, a VLAN-Stack trunk port is configured and then also made part of a single-tagged
VLAN.
In the second example, the tag protocol identifier (TPID) is set to 8848. The “Gi 3/10” Te 3/8 port
is configured to act as a VLAN-Stack access port, while the “TenGi 8/0” 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, the native VLAN feature is required, by
executing the portmode hybrid command. Refer to portmode hybrid in the Interfaces chapter.
