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, rst remove the port (using the no member interface
command) from all stackable VLAN-enabled VLANs.
In Example 1, a VLAN-Stack trunk port is congured and then made part of a single-tagged VLAN.
In Example 2, the tag protocol identier (TPID) is set to 8848. The Gi 3/10 port is congured to act as a
VLAN-Stack access port; the TenGi 8/0 port acts as a VLAN-Stack trunk port, switching stackable VLAN
trac for VLAN 10, while also switching untagged trac for VLAN 30 and tagged trac for VLAN 40. (To
allow VLAN 30 trac, you need the native VLAN feature. Use the portmode hybrid command. For
more information, see the
portmode hybrid command.
