Command
Usage
Information
Prior to using this command, to place the interface in Layer 2 mode, use 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.
In Example 1, a VLAN-Stack trunk port is configured and then made part of a single-tagged VLAN.
In Example 2, the tag protocol identifier (TPID) is set to 88A8. The Te 3/10 port is configured to act as
a VLAN-Stack access port; the Te 5/1 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, you need the native VLAN feature. Use the portmode hybrid command.
For more information, see the portmode hybrid command.
