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, rst 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 congured 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 congured and then also made part of a single-tagged VLAN.
In Example 2, the tag protocol identier (TPID) is set to 8848. The “Gi 3/10” port is congured to act as a
VLAN-Stack access port, while the “TenGi 8/0” port acts as a VLAN-Stack trunk port, switching stackable
VLAN trac for VLAN 10, while also switching untagged trac for VLAN 30 and tagged trac for VLAN 40.
(To allow VLAN 30 trac, the native VLAN feature is required, by executing the portmode hybrid
command. Refer to portmode hybrid in Interfaces.
