Releasing And Renewing Dhcp-Based Ip Addresses; Viewing Dhcp Statistics And Lease Information - Dell PowerEdge M IO Aggregator Command Reference Manual

Releasing and Renewing DHCP-based IP Addresses

On an Aggregator configured as a DHCP client, you can release a dynamically-assigned IP address
without removing the DHCP client operation on the interface. You can later manually acquire a new IP
address from the DHCP server as follows:
Task
Release a dynamically-acquired IP address while retaining
the DHCP client configuration on the interface.
Acquire a new IP address with renewed lease time from a
DHCP server.
