Chapter 15 - VLAN Commands

The AT-9724TS incorporates the idea of protocol-based VLANs.This standard, defined by the IEEE 802.1v standard maps packets to protocol-defined VLANs by
examining the type octet within the packet header to discover the type of protocol associated with it.After assessing the protocol, the Switch will forward the
packets to all ports within the protocol-assigned VLAN.This feature will benefit the administrator by better balancing load sharing and enhancing traffic
classification.The switch supports fifteen (15) pre-defined protocols for configuring protocol-based VLANs.The user may also choose a protocol that is not one
of the fifteen defined protocols by properly configuring the user defined protocol VLAN.The supported protocols for the protocol VLAN function on this Switch
include IP, IPX, DEC, DEC LAT, SNAP, NetBIOS,AppleTalk, XNS, SNA, IPv6, RARP and VINES.
The VLAN commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the following table.

This command allows you to create a VLAN on the Switch.The user may choose between an 802.1Q VLAN or
a protocol-based VLAN.
<vlan_name 32> – The name of the VLAN to be created.
tag <vlanid 2-4094> – The VLAN ID of the VLAN to be created.Allowed values = 2-4094
type – This parameter uses the type field of the packet header to determine the packet protocol and
destination VLAN.There are two main choices of types for VLANs created on the Switch:
1q_vlan – Allows the creation of a normal 802.1Q VLAN on the Switch.
advertisement – Specifies that the VLAN is able to join GVRP. If this parameter is not set, the VLAN cannot be
configured to have forbidden ports.
The following parameters allow for the creation of protocol-based VLANs.The Switch supports 15 pre-
configured protocol-based VLANs plus one user defined protocol based VLAN where the administrator may
configure the settings for the appropriate protocol and forwarding of packets (16 total). Selecting a specific
protocol will indicate which protocol will be utilized in determining the VLAN ownership of a tagged packet.
Pre-set protocol-based VLANs on the Switch include:
protocol-ip – Using this parameter will instruct the Switch to forward packets to this VLAN if the tag in the
packet header is concurrent with this protocol.This packet header information is based on the Ethernet
protocol.
protocol-ipx802dot3 – Using this parameter will instruct the Switch to forward packets to this VLAN if the tag in
the packet header is concurrent with this protocol.This packet header information is defined by Novell
NetWare 802.3 (IPX - Internet Packet Exchange).
