If you select the bootp or dhcp option, IP is enabled but does not function until a BOOTP or DHCP reply has been received. Requests are broadcast
periodically by the switch in an effort to learn its IP address. (BOOTP and DHCP values can include the IP address, default gateway, and subnet mask).
To display assigned IP settings using the CLI:
1. From the Privileged Exec or Normal Exec level mode, type show ip interface and press <Enter>.
The assigned IP address and subnet mask displays.
2. From the Privileged Exec mode, type show ip redirects to display the assigned gateway IP address. Press <Enter>.
The following example displays IP settings assigned by bootp or dhcp using the CLI.
Console#show ip interface
IP address and netmask: 10.1.0.1 255.255.252.0 on VLAN 1,
and address mode: User specified.
Console# show ip redirects
ip default gateway 10.1.0.254
Console#
Before you can assign a static IP address to the switch, you must obtain the following information from your network administrator:
IP address for the switch
l
Default gateway for the network
l
Network mask for the network
l
To assign a static IP address to the switch:
1. From the Privileged Exec level 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.
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>.
5. To save your configuration changes, type copy running-config startup-config and then press <Enter>.
NOTICE: Only one VLAN can be assigned an IP address. If you assign an address to any other VLAN, the new address overrides the original IP
address.
The following example shows how to set a static IP address using the CLI.
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)#
To configure the switch for DHCP or BOOTP:
