7ADMINISTERING IP ROUTING
This chapter describes how to set up your LANplex system to route packets
using IP. For more information about how IP works, see Part II of this Guide.
You can display and/or configure the following:
■IP interfaces
■Routes
■Address Resolution Protocol (ARP) cache
■UDP Helper
■IP forwarding
■Routing Information Protocol (RIP)
■Ping
■IP statistics
Each switching module operates as a separate IP router. This means that
each module has its own interfaces, routing table, ARP cache, and statistics.
Administering
Interfaces
You define interfaces to establish the relationship between the ports on
your switching modules and the subnets in your IP network. You must
define one interface for each group of ports that are connected to the same
subnet. This means that every switching module has one interface defined
for each subnet to which it is directly connected.
An IP interface has the following information associated with it:
■IP Address
This is the address specific to your network. It should be chosen from the
range of addresses assigned to your organization. An interface’s IP address
serves two functions. First, it is the address that is used when sending IP
