Command Modes INTERFACE Command History Version 8.3.16.1 Introduced on MXL 10/40GbE Switch IO Module Usage Prior to using this command, to place the interface in Layer 2 mode, you must execute the switchport Information 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. VLAN Stacking | 661

Syntax

vlan-stack trunk

To remove a trunk port designation from the selected interface, use the

no vlan-stack trunk

command.

Defaults

Not configured.

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

Figure 37-4

, a VLAN-Stack trunk port is configured and then also made part of a single-tagged

VLAN.

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
