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 congured and then made part of a single-tagged VLAN.
In Example 2, the tag protocol identier (TPID) is set to 88A8. The Gi 3/10 port is congured to act as a VLAN-
Stack access port; the Gi 5/1 port acts as a VLAN-Stack trunk port, switching stackable VLAN trac for VLAN 10,
while also switching untagged trac for VLAN 30 and tagged trac for VLAN 40. (To allow VLAN 30 trac, you
need the native VLAN feature. Use the portmode hybrid command. For more information, see the portmode
hybrid command.
