Ip dhcp restart

ip dhcp restart 59

•An default gateway can only be successfully set when a network interface that directly connects to the gateway has been configured on the switch.

Example

The following example defines a default gateway for this device:

Console(config)#ip default-gateway 10.1.1.254

Console(config)#

Related Commands

show ip redirects (59-4) ipv6 default-gateway(60-12)

This command submits an IPv4 BOOTP or DHCP client request.

Default Setting

None

Command Mode

Privileged Exec

Command Usage

•This command issues a BOOTP or DHCP client request for any IP interface that has been set to BOOTP or DHCP mode via the ip address command.

•DHCP requires the server to reassign the client’s last address if available.

•If the BOOTP or DHCP server has been moved to a different domain, the network portion of the address provided to the client will be based on this new domain.

Example

In the following example, the device is reassigned the same address.

Console(config)#interface vlan 1 Console(config-if)#ip address dhcp Console(config-if)#end Console#ip dhcp restart Console#show ip interface

IP address and netmask: 192.168.1.54 255.255.255.0 on VLAN 1,

and address mode: DHCP. Console#
