Manual Configuration
You can manually assign an IP address to the switch. You may also need to specify
a default gateway that resides between this device and management stations that
exist on another network segment (if routing is not enabled on this switch). Valid IP
addresses consist of four decimal numbers, 0 to 255, separated by periods.
Anything outside this format will not be accepted by the CLI program.
Note:
An IPv4 address for this switch is obtained via DHCP by default.
Assigning an IPv4 Address
Before you can assign an IP address to the switch, you must obtain the following
information from your network administrator:
• IP address for the switch
• Network mask for this network
• Default gateway for the network
To assign an IPv4 address to the switch, complete the following steps:
1. From the Global Configuration mode prompt, type “interface vlan 1” to access
the interface-configuration mode. Press <Enter>.
2. Type “ip address ip-address netmask,” where “ip-address” is the switch IP
address and “netmask” is the network mask for the network. Press <Enter>.
3. Type “exit” to return to the global configuration mode prompt. Press <Enter>.
4. To set the IP address of the default gateway for the network to which the switch
belongs, type “ip default-gateway gateway,” where “gateway” is the IP address
of the default gateway. Press <Enter>.
Console(config)#interface vlan 1
Console(config-if)#ip address 192.168.1.5 255.255.255.0
Console(config-if)#exit
Console(config)#ip default-gateway 192.168.1.254

As
signing an IPv6 Address
There are several ways to manually configure IPv6 addresses. This section
describes how to configure a “link local” address for connectivity within the local
subnet only, and another option that allows you to specify a “global unicast” address
by first configuring a network prefix for use on a multi-segment network, and then
configuring the host address portion of the address.
A
n IPv6 prefix or address must be formatted according to RFC 2373 “IPv6
A
ddressing Architecture,” using 8 colon-separated 16-bit hexadecimal values. One
double colon may be used to indicate the appropriate number of zeros required to fill
