Command History
Version Description
9.9(0.0) Introduced on the FN IOM.
8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
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 the 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 the rst example, a VLAN-Stack trunk port is congured and then also made part of a single-tagged VLAN.
In the second example, the tag protocol identier (TPID) is set to 8848. The “Gi 3/10” Te 3/8 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 the Interfaces chapter.
