Chapter 1 | Initial Switch Configuration
Configuring the Switch for Remote Management
– 59 –
If the “bootp” or “dhcp” option is saved to the startup-config file (step 6), then the
switch will start broadcasting service requests as soon as it is powered on.
To automatically configure the switch by communicating with BOOTP or DHCP
address allocation servers on the network, complete the following steps:
1. From the Global Configuration mode prompt, type “interface vlan 1” to access
the interface-configuration mode. Press <Enter>.
2. At the interface-configuration mode prompt, use one of the following
commands:
■
To obtain IP settings via DHCP, type “ip address dhcp” and press <Enter>.
■
To obtain IP settings via BOOTP, type “ip address bootp” and press <Enter>.
3. Type “end” to return to the Privileged Exec mode. Press <Enter>.
4. Wait a few minutes, and then check the IP configuration settings by typing the
“show ip interface” command. Press <Enter>.
5. Then save your configuration changes by typing “copy running-config startup-
config.” Enter the startup file name and press <Enter>.
Console(config)#interface vlan 1
Console(config-if)#ip address dhcp
Console(config-if)#end
Console#show ip interface
VLAN 1 is Administrative Up - Link Up
Address is 00-E0-0C-00-00-FB
Index: 1001, MTU: 1500
Address Mode is DHCP
IP Address: 192.168.0.2 Mask: 255.255.255.0
Proxy ARP is disabled
Console#copy running-config startup-config
Startup configuration file name []: startup

Success.
Obtaining an IPv6 Address
Link Local Address — There are several ways to configure IPv6 addresses. The
simplest method is to automatically generate a “link local” address (identified by an
address prefix in the range of FE80~FEBF). This address type makes the switch
accessible over IPv6 for all devices attached to the same local subnet.
To generate an IPv6 link local address for 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 “ipv6 enable” and press <Enter>.
