Basic Configuration 2

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

Default gateway for the network

Network mask for this network

To assign an IP 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

Console(config)#

Dynamic Configuration

If you select the “bootp” or “dhcp” option, IP will be enabled but will not function until a BOOTP or DHCP reply has been received. You therefore need to use the “ip dhcp restart client” command to start broadcasting service requests. Requests will be sent periodically in an effort to obtain IP configuration information. (BOOTP and DHCP values can include the IP address, subnet mask, and default gateway.)

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.Type “ip dhcp restart client” to begin broadcasting service requests. Press <Enter>.
