Key Guidelines for Implementing IP Routing
371
Layer 3 module prompts you for this option, the menu identifies the
available VLAN indexes.
Important Consideration
Consider the following issue before you establish an IP interface:
■
Before you assign IP addresses, map out the entire network and
subnetwork IP addressing scheme. Plan for future expansion of
address numbers as well.
The
ip interface define
(in-band) and
management ip interface
define
(out-of-band) options are documented in the Command
Reference Guide . To learn how to use the Web Management Console to
set up IP interfaces, see the Switch 4007 Getting Started Guide .
Defining an IP Interface
After you determine the VLAN index, IP address, and subnet mask for
each IP interface, you can define each interface. Use the Administration
Console or the Web Management Console to define an IP interface.
Remember that you must define a VLAN and select IP as a protocol that
the VLAN supports before you define the IP (routing) interface. VLANs are
described in
Chapter 14 .
To define your IP interface, decide if and how to implement the following
IP features:
■
ARP proxy
■
ICMP Redirect
■
ICMP Router Discovery
■
Broadcast address
■
Directed broadcast
■
RIP
■
Routing policies
■
DNS
■
UDP Helper
These features are discussed later in this chapter.
