Assigning IP Addresses to Network Interfaces
An IP address identifies a location to which IP packets can be sent. Some IP addresses are reserved for
special uses and cannot be used for host, subnet, or network addresses. RFC 1166, "Internet Numbers,"
contains the official description of IP addresses.
An interface can have one primary IP address. A mask identifies the bits that denote the network number
in an IP address. When you use the mask to subnet a network, the mask is referred to as a subnet mask.
To receive an assigned network number, contact your Internet service provider.
Beginning in privileged EXEC mode, follow these steps to assign an IP address and a network mask to
a Layer 3 interface:
Command
Step 1
configure terminal
Step 2
interface interface-id
Step 3
no shutdown
Step 4
no switchport
Step 5
ip address ip-address subnet-mask
Step 6
end
Step 7
show interfaces [interface-id]
show ip interface [interface-id]
show running-config interface [interface-id]
Step 8
copy running-config startup-config

Default Setting
Disabled.
Defaults when enabled:
Broadcast IRDP advertisements.
•
Maximum interval between advertisements: 600 seconds.
•
Minimum interval between advertisements: 0.75 times max interval
•
•
Preference: 0.
Enabled.
Disabled.
Disabled.
Purpose
Enter global configuration mode.
Enter interface configuration mode, and specify the Layer 3
interface to configure.
Enable the interface if necessary. User network interfaces
(UNIs) are disabled by default; network node interfaces (NNIs)
are enabled by default.
Remove the interface from Layer 2 configuration mode (if it is a
physical interface).
Configure the IP address and IP subnet mask.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
