Command Line Reference Guide

VLAN Stacking | 1479
Usage
Information
Prior to using this command, you must execute the switchport command to place the interface in
Layer 2 mode.
To remove the trunk port designation, the port must first be removed (using the no member interface
command) from all Stackable VLAN-enabled VLANs.
Starting with Dell Networking OS 7.7.1.0 for E-Series, the VLAN-Stack trunk port can transparently
tunnel, in a service provider environment, customer-originated xSTP control protocol PDUs. See
Chapter 52, Service Provider Bridging.
Starting with Dell Networking OS 7.8.1.0 for C-Series and S-Series (Dell Networking OS 7.7.1 for
E-Series), 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. See portmode hybrid.
In Example 1 below, a VLAN-Stack trunk port is configured and then also made part of a single-tagged
VLAN.
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. See portmode hybrid in Interfaces.
