Configuring IP
This chapter describes the Internet Protocol (IP) parameters on the Virtual ADX and how to
configure them.
Basic configuration
IP is enabled by default. Basic configuration consists of adding IP addresses and enabling a route
exchange protocol. Refer to
“Configuring IP addresses” on page 54 to add IP addresses, then see
one or more of the following to enable and configure the route exchange protocols:
The rest of this chapter describes IP and how to configure it in more detail. Use the information in
this chapter if you need to change some of the IP parameters from their default values or you want
to view configuration information or statistics.
Overview
IP interfaces
Virtual ADX allows you to configure IP addresses. IP addresses are associated with individual
interfaces.
Virtual ADX supports configuration and display of IP address in classical subnet format (example:
192.168.1.1 255.255.255.0) and Classless Interdomain Routing (CIDR) format (example:
192.168.1.1/24). You can use either format when configuring IP address information. IP addresses
are displayed in classical subnet format by default but you can change the display format to CIDR.
Refer to
“Changing the network mask display to prefix format” on page 85.
Virtual ADX allows you to configure IP addresses on the following types of interfaces:
• Ethernet ports
• Virtual routing interfaces (used by VLANs to route among one another)
• Loopback interfaces
Each IP address on a Virtual ADX device must be in a different subnet. You can have only one
interface that is in a given subnet. For example, you can configure IP addresses 192.168.1.1/24
and 192.168.2.1/24 on the same Virtual ADX, but you cannot configure 192.168.1.1/24 and
192.168.1.2/24 on the same Virtual ADX.
You can configure multiple IP addresses on the same interface.
You can use any of the IP addresses you configure on the Virtual ADX for Telnet, Web management,
or SNMP access.
The following sections describe the IP tables and caches:
• ARP cache and static ARP table
