purpose use of the port.
7.6.1.0 Introduced on the C-Series and S-Series.
E-Series original
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.
