DHCP Management Interface Commands

console#release dhcp vlan2

Use the renew dhcp command in Privileged EXEC mode to force the DHCP 

client to immediately renew an IPv4 address lease.

renew dhcp {

interface-id | out-of-band}

This command has no default configuration.

Privileged EXEC

If the interface has a leased IPv4 address when this command is issued, the 

DHCP client sends a DHCP REQUEST message telling the DHCP server 

that it wants to continue using the IP address. If DHCP is enabled on the 

interface, but the interface does not currently have an IPv4 address (for 

example, if the address was previously released), then the DHCP client sends 

a DISCOVER to acquire a new address. If DHCP is not enabled on the 

interface, then the command fails and displays the following error message:

DHCP is not enabled on this interface

interface-id

Any valid routing interface. See 

 

for interface representation.

out-of-band

Keyword to identify the out-of-band interface. The DHCP 

client renews the leased address on this interface.
