Administrator Guide

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 88A8. The Gi 3/10 port is congured to act as a VLAN-
Stack access port; the Gi 5/1 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.
