Dhcp Client - Dell PowerEdge M IO Aggregator Command Reference Manual

FTOS Behavior: DHCP is implemented in FTOS based on RFC 2131 and 3046.

DHCP Client

An Aggregator is auto-configured to operate as a DHCP client. The DHCP client functionality is enabled
only on the default VLAN and the management interface.
A DHCP client is a network device that requests an IP address and configuration parameters from a DHCP
server. On an Aggregator, the DHCP client functionality is implemented as follows:
• The public out-of-band management (OOB) interface and default VLAN 1 are configured, by default,
as a DHCP client to acquire a dynamic IP address from a DHCP server.
You can override the DHCP-assigned address on the OOB management interface by manually config-
uring an IP address using the CLI or CMC interface. If no user-configured IP address exists for the
OOB interface exists and if the OOB IP address is not in the startup configuration, the Aggregator will
automatically obtain it using DHCP.
You can also manually configure an IP address for the VLAN 1 default management interface using
the CLI. If no user-configured IP address exists for the default VLAN management interface exists and
if the default VLAN IP address is not in the startup configuration, the Aggregator will automatically
obtain it using DHCP.
• The default VLAN 1 with all ports configured as members is the only L3 interface on the Aggregator.
When the default management VLAN has a DHCP-assigned address and you reconfigure the default
VLAN ID number, the Aggregator:
• Sends a DHCP release to the DHCP server to release the IP address.
• Sends a DHCP request to obtain a new IP address. The IP address assigned by the DHCP server is
used for the new default management VLAN.
