Command
Usage
Information
Prior to using this command, to place the interface in Layer 2 mode, execute 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.
Starting with 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 Example 1, a VLAN-Stack trunk port is configured and then also made part of a single-tagged VLAN.
In Example 2, the tag protocol identifier (TPID) is set to 8848. The “Gi 3/10” 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 Interfaces.
