A port configured this way is identified as a hybrid port in report displays. Specify a Layer 2 port or port channel as a trunk port to the Stackable VLAN network. vlan-stack trunk c e s Specify a Layer 2 port or port channel as a trunk port to the Stackable VLAN network. Syntax vlan-stack trunk To remove a trunk port designation from the selected interface, enter no vlan-stack trunk. Defaults Not configured. Command Modes INTERFACE Command History Version 8.2.1.0 Introduced on the E-Series ExaScale Version 7.8.1.0 Functionality augmented for C-Series and S-Series to enable multi-purpose use of the port. See Usage Information, below. Version 7.7.1.0 Functionality augmented for E-Series to enable multi-purpose use of the port. See Usage Information, below. Version 7.6.1.0 Introduced for C-Series and S-Series E-Series original Command Usage Prior to using this command, you must execute the switchport command to place the interface in Information 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 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. See Chapter 52, Service Provider Bridging. Starting with FTOS 7.8.1.0 for C-Series and S-Series (FTOS 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 should be in hybrid mode. See 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 will act 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. See portmode hybrid in Interfaces. 1462 | VLAN Stacking
