This topic describes how to configure VLAN trunk ports for multiple zones on SteelHead SD. It includes
these sections:
• “Overview of multizone VLAN trunk mode on SteelHead SD” on page 37
• “Defining trunk mode on ports” on page 38
These procedures describe how to configure multizone VLAN trunk ports on SteelHead SD 570-SD, 770-
SD, and 3070-SD appliances and the SteelConnect SDI-2030 gateway located at the branch. For details

Overview of multizone VLAN trunk mode on SteelHead SD
Multiple VLANs are very common in Layer 2 (L2) network environments on the LAN side. With this
feature, you can configure multiple VLANs on the same LAN port (that is, trunk port functionality). VLANs
are used for segmenting networks at L2 and provide basic security for network traffic by limiting
broadcast domains and network flooding.
SteelHead SD supports trunk mode VLANs for zones. You can define a trunk port on a zone and
configure it with different VLANs. For example, you can have a trunk port on the LAN side with two zones
configured with different VLANs.
