tagged VLANs. When the VLAN-Stack trunk port is also a member of an untagged
VLAN, the port must be in Hybrid mode. Refer to
In the first example, a VLAN-Stack trunk port is configured and then also made part
of a single-tagged VLAN.
In the second example, 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 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, the native VLAN feature is required, by executing the
portmode hybrid command. Refer to
