both bytes of the 2-byte S-Tag TPID.
Version 7.8.1.0 Functionality augmented for C-Series and S-Series to enable multi-
purpose use of the port.
Version 7.7.1.0 Functionality augmented for E-Series to enable multi-purpose use of

Command
Usage
Information
Prior to using this command, you must execute the switchport command to place the
interface in Layer 2 mode.
To remove the trunk port designation, the port must first be removed (using the no member
interface command) from all stackable VLAN-enabled VLANs.
Starting with FTOS version 7.7.1.0 for E-Series, the VLAN-Stack trunk port can transparently
tunnel, in a service provider environment, customer-originated xSTP control protocol PDUs.
Refer to Service Provider Bridging.
Starting with FTOS version 7.8.1.0 for C-Series and S-Series (FTOS version 7.7.1 for E-Series), 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 below, a VLAN-Stack trunk port is configured and then also made part of a single-
tagged VLAN.
In Example 2 below, 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.
