6.1.4 Configuring DHCP Client
Before a DHCP client applies for an IP address, you must create a VLAN, and add the
interface of the IP address to the VLAN. Meanwhile you must configure the DHCP server,
otherwise the interface will fail to obtain the IP address through DHCP.
For interface IP 0, the IP addresses obtained through DHCP and configured manually can
overwrite each other.
By default, the ISCOM2600G-HI series switch is enabled with DHCP Client. Use
the
no ip address dhcp
command to disable DHCP Client.
If the ISCOM2600G-HI series switch obtains the IP address from the DHCP server
through DHCP previously, it will restart the application process for IP address if
you use the
ip address dhcp
command to modify the IP address of the DHCP
server.
Configure DHCP Client for the ISCOM2600G-HI series switch as below.

After the IP address is obtained by a
DHCP client, client information cannot be
modified.

If the Layer 3 interface of the DHCP client has
obtained an IP address through DHCP, the IP
address will automatically be renewed when
the lease period expires.
