Enterasys Networks 2H253, 2E253, 2H252, 2H258 manual Examples, Example 1, Single Switch Operation

Examples

This effectively completes the configuration of a single VLAN, assigning it to a port, and configuring the switch to forward the frames received on that port to a trunk port. The trunk port in turn forwards the frames as tagged to another switch.

You can now use the VLAN Classification Configuration and Port Protocol Configuration screens to transmit frames according to classification rules and associated ports, as described in Chapter 7.

12.11 EXAMPLES

NOTE: Due to the complexity of Local Management, the following simple examples are not meant to cover the full potential of Local Management.

The following sections provide some examples of how VLAN-aware SmartSwitches can be configured to group users at the port level to create VLANs in existing networks. Each example presents a problem and shows how it is solved by configuring the switches using the VLAN Local Management screens. The actual procedures and screens used to configure a VLAN-aware switch are covered in Chapter 7. Also provided in the discussion of each example is a description of how the frames transmitted from one user would traverse the network to its target device.

12.12 EXAMPLE 1, SINGLE SWITCH OPERATION

This first example looks at the configuration of a single Ethernet switch for VLAN operation. In this example, two groups of three users are to be assigned to two VLANs to isolate them from one another. The blue users (B1, B2, B3) are to be kept completely separate from the red users (R1, R2, R3). Figure 12-10shows the initial state of the switch.
