Command History
Version Description
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, 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 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.
