350CHAPTER 14: VIRTUAL LANS (VLANS)

4Specify whether you want to specify Layer 3 address information (n or y). The default is y. Specify n if possible and instead define multiple IP interfaces for this VLAN using ip interface define commands. (See Chapter 16.) If you still want to specify Layer 3 address information for an

IP VLAN:

a Enter y for Layer 3 addressing.

b Enter the Layer 3 network address.

c Enter the Layer 3 subnet mask. To accept the default or current value in brackets [ ], press Return or Enter.

5Specify whether you want per-port tagging (n or y). The default is y.

6If you specified per-port tagging, enter the tag type for the indicated port (none or 802.1Q).

7If you have defined more than one port, you are prompted again for a tag type for each port.

8Enter the VLAN name.

Bridge VLAN Define Example (9000 Layer 3)

This example shows the steps necessary to define a protocol-based VLAN for IPX 802.3 on a Layer 3 switching module. In this example, only the backplane port (port 13) of the module has IEEE 802.1Q tagging; the front-panel ports in this VLAN are not tagged. Because you have tagged the module’s backplane port, you must also tag the corresponding switch fabric module port of the switch fabric module for that VLAN. (Use the EME to connect to the switch fabric module and configure the VLAN.)
