Reference Guide

In Example 2, 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 portmode hybrid in
Interfaces.
