Table 5-9. VLAN Example – Assigned IP Addresses

The 6 IP interfaces, each with an IP address (listed in the table above), and a subnet mask of 255.224.0.0 can be entered into the Setup IP Interface menu.

Layer 3-Based VLANs

Layer 3-based VLANs use network-layer addresses (subnet address for TCP/IP) to determine VLAN membership. These VLANs are based on layer 3 information, but this does not constitute a ‘routing’ function.

The DES-3326 allows an IP subnet to be configured for each 802.1Q VLAN that exists on the switch.

Even though a switch inspects a packet’s IP address to determine VLAN membership, no route calculation is performed, the RIP protocol is not employed, and packets traversing the switch are bridged using the Spanning Tree algorithm.

A switch that implements layer 3 (or ‘subnet’) VLANs without performing any routing function between these VLANs is referred to as performing ‘IP Switching’.

Internet Protocols

This is a brief introduction to the suite of Internet Protocols frequently referred to as TCP/IP. It is intended to give the reader a reasonable understanding of the available facilities and some familiarity with terminology. It is not intended to be a complete description.
