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 manage ment sta tions 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, se parated b y 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 ob tain th e followi ng
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 followin g steps :
1. From the Global Configuration mode prompt, type “int erface vla n 1” to acce ss
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. Pr ess <Ente r>.
4. To set the IP address of the default gateway for t he ne two rk t o wh ic h t he s w it ch
belongs, type “ip default-gateway gateway,” where “gateway” is the IP addres s
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 connect ivity within the local
subnet only, and another option that allows you to specify a “glo bal u nica st” a ddre ss
by first configuring a network prefix for use on a multi-segment netw ork, and the n
configuring the host address portion of the address.
A
n IPv6 prefix or address must be form atted acco rding to R FC 2373 “IP v6
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
