1.6.7.2 Renew Client
The DHCP client lease can be renewed by user configuration. The renew dhcp command advances the
DHCP lease timer to the next stage, after which a DHCP REQUEST packet is sent to renew or rebind the
lease.
• If the lease is currently in a BOUND state, the lease is advanced to the RENEW state and a
DHCPRENEW request is sent. If there is no response to the RENEW request, the interface remains in the
RENEW state and the lease timer will advance to the REBIND state beforesending a REBIND request. If a
NAK response is sent in response to the RENEW request, the interface IP address is de-configured. The
original IP address for the interface must then be assigned by the DHCP server.
• If the lease is currently in a RENEW state, the timer is advanced to the REBIND state and a
DHCPREBIND request is sent.
Follow the steps below to configure the DHCP Client.
Step Command
Step 1 configure terminal
interface vlan<vlan-id
Step 2
loopback <interface-id (1-100)>
Step 3 no switchport
Step 3 ip address dhcp
Step 4 exit
Step 5 renew dhcp [{ vlan<vlan-id (1-4069)> | <interface-
type><interface-id> }]
Step 6 release dhcp [{ vlan<vlan-id (1-4069)> | <interface-
type><interface-id> }]
Step 7 end
show ip interface
Step 8
The VLAN should be created before configuring the VLAN client on that particular VLAN.
The "no ip address dhcp" command deletes the DHCP client configuration.
The example below shows the commands used to configure a DHCP Client.
SMIS(config)# interface Gi 0/22
SMIS(config-if)# no switchport
SMIS(config-if)# ip address dhcp
(1-4069)>| interface
