Enabling the DHCP client on an interface
Follow these guidelines when you enable the DHCP client on an interface:
If the number of IP address request failures reaches the system-defined amount, the DHCP client-enabled interface uses a default IP address.
An interface can be configured to acquire an IP address in multiple ways. The new configuration overwrites the old.
Secondary IP addresses cannot be configured on an interface that is enabled with the DHCP client.
If the interface obtains an IP address on the same segment as another interface on the device, the interface does not use the assigned address. Instead, it requests a new IP address from the DHCP server.
To enable the DHCP client on an interface:
