350 C HAPTER 14: V IRTUAL LAN S (VLAN S )
4 Specify 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.
5 Specify whether you want per-port tagging ( n or y ). The default is y .
6 If you specified per-port tagging, enter the tag type for the indicated port
( none or 802.1Q ).
7 If you have defined more than one port, you are prompted again for a tag
type for each port.
8 Enter 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.)
