SonicOS 5.7: Advanced Switching Feature Guide and Screencast Tutorial
The values displayed on the Switching > VLAN Trunking page are described in Table 1.
Table 1 VLAN Trunking Page Description
Item Description
Reserved VLAN Information
Starting VLAN ID The lowest ID number in the VLAN range reserved for PortShield use. This
VLAN range is reserved for local VLANs associated with a PortShield group.
Ending VLAN ID The highest ID number in the VLAN range reserved for PortShield use.
VLAN Table
VLAN ID The ID number of the VLAN. VLAN ID 26 is the default VLAN that includes
all LAN ports on the SonicWALL NSA 2400MX unless configured otherwise.
Interface
• For the default VLAN that includes all LAN ports unless configured
otherwise, the lowest interface, X0, is used.
• For other VLANs with multiple member ports, the displayed interface is
the one configured as the PortShield interface for that PortShield group.
• For interfaces that are not assigned to a PortShield group, the port number
of the interface is used, such as X25.
• For remote VLANs, the trunked interface and the virtual interface (called
the VLAN Trunk Interface) are displayed in the format:
[trunked interface]:V[virtual interface number]
The virtual VLAN Trunk Interface is automatically created for remote
VLANs. When the same remote VLAN is enabled on another trunk port,
no new interface is created. All packets with the same VLAN tag ingressing
on different trunk ports are handled by the same virtual interface.
Member Ports
• For PortShield groups, all interfaces in the group are listed as Member
Ports.
• For interfaces that are not assigned to a PortShield group, only the port
number of the interface is listed as a Member Port.
• For remote VLANs, the VLAN trunk ports on which the remote VLAN is
enabled are listed.
Trunked A green check mark is displayed if the VLAN ID has been configured as
trunked, and is enabled for trunking on all VLAN trunk ports. A VLAN can be
enabled for trunking on an individual trunk port or a subset of all trunk ports,
in which case the green check mark does not appear. Enabling trunking allows
traffic for this VLAN to be sent to remote members of the VLAN who are
connected to a different switch in the network. To enable trunking for this
VLAN on all trunk ports, see the “Editing VLANs” section on page 12.
Configure The Configure icon is enabled for rows that contain PortShield groups. When
the Configure icon is disabled, you can edit the settings for that row on the
Network > PortShield Groups page.
VLAN Trunks
Trunk Port The interface name is displayed in the Trunk Port column. Also, the number of
VLAN entries that are enabled on this trunk port is given in parentheses.
