Usage
Information
Prior to using this command, to place the interface in Layer 2 mode, you must execute the switchport
command.
To remove the trunk port designation, the port must first be removed (using the no member interface
command) from all stackable VLAN-enabled VLANs.
A VLAN-Stack trunk port is also allowed to be configured as a tagged port and as an untagged port for
single-tagged VLANs. When the VLAN-Stack trunk port is also a member of an untagged VLAN, the
port should be in hybrid mode. For more information, refer to portmode hybrid.
In Figure 37-4, a VLAN-Stack trunk port is configured and then also made part of a single-tagged
VLAN.
In Figure 37-5, the tag protocol identifier (TPID) is set to 8848. The “Tengig 3/10” port is configured
to act as a VLAN-stack access port, while the “Tengig 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
using the portmode hybrid command. For more information, refer to portmode hybrid in the Interfaces
chapter.
Version 8.3.16.1 Introduced on MXL 10/40GbE Switch IO Module
portmode hybrid Sets a port (physical ports only) to accept both tagged and untagged frames. A port
configured this way is identified as a hybrid port in report displays.
vlan-stack trunk Specifies a Layer 2 port or port channel as a trunk port to the stackable VLAN network.
