VLAN Stacking | 1517
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. Refer to portmode hybrid in Interfaces.
