ADMINISTERING IP ROUTING
This chapter describes how to set up your LANplex® system to use the
Internet Protocol (IP). For more information about how IP works, see Part III
of this guide.
You can display or configure the following IP characteristics on your
LANplex system:
■ IP interfaces
■ Routes
■ Address Resolution Protocol (ARP) cache
■ UDP Helper
■ ATM ARP Server (for LANplex systems with ATM modules)
■ IP Routing
■ ICMP Router Discovery
■ Routing Information Protocol (RIP)
■ Ping
■ IP statistics
Administering
interfaces
You can define two types of IP interfaces through LANplex Extended
Switching software: IP VLAN interfaces and IP LIS interfaces. This section
describes these interfaces and how to administer them.
An IP VLAN interface defines the relationship between an IP Virtual LAN
(VLAN) and the subnets in the IP network. Every IP VLAN interface has one
IP VLAN associated with it. Each Ethernet or FDDI switching module has one
interface defined for each subnet directly connected to it. You must first
define a VLAN, as described in Chapter 8, Administering VLANs, before you
define an associated IP VLAN interface.
