12 Configuring IP
Internet Protocol (IP) is primarily a network-layer (Layer 3) protocol that contains addressing and control
information that enables packets to be forwarded. Along with Transmission Control Protocol (TCP), IP
represents the heart of the Internet protocols. IP has two primary responsibilities: providing connection-
less, best-effort delivery of datagrams through an internetwork; and providing fragmentation and reassem-
bly of datagrams to support data links with different Maximum Transmission Unit (MTU) sizes.
Note.
IP routing (Layer 3) requires one of the IP routing protocols: Routing Information Protocol (RIP),
Open Shortest Path First (OSPF). For more information on these protocols see
Chapter 13, “Configuring
RIP,”
in this manual; or “Configuring OSPF” in the
OmniSwitch 6624/6648 Advanced Routing Configura-
tion Guide
.
In This Chapter
This chapter describes IP and how to configure it through the Command Line Interface (CLI). It includes
instructions for enabling IP forwarding, as well as basic IP configuration commands (e.g.,
ip default-ttl
).
CLI commands are used in the configuration examples; for more details about the syntax of commands,
see the
OmniSwitch CLI Reference Guide
. This chapter provides an overview of IP and includes informa-
tion about the following procedures:
•
IP Forwarding
– Creating an IP Router Port (see page
12-5
)
– Creating a Static Route (see page
12-6
)
– Creating a Default Route (see page
12-6
)
– Configuring Address Resolution Protocol (ARP) (see page
12-7
)
•
IP Configuration
– Configuring the Router Primary Address (see page
12-9
)
– Configuring the Router ID (see page
12-9
)
– Configuring the Time-to-Live (TTL) Value (see page
12-9
)
– IP-Directed Broadcasts (see page
12-10
)
– Protecting the Switch from Denial of Service (DoS) attacks (see page
12-10
)
•
Managing IP
– Internet Control Message Protocol (ICMP) (see page
12-15
)
– Using the Ping Command (see page
12-19
)
– Tracing an IP Route (see page
12-19
)
– Displaying TCP Information (see page
12-19
)
– Displaying User Datagram Protocol (UDP) Information (see page
12-20
)
