Forcing Renewal of the BIG-IP System Management Port DHCP Lease

About the BIG-IP system management port and DHCP

The BIG-IP® system uses the management port for administrative traffic. The system does not forward application traffic, such as traffic slated for load balancing, through this interface.

By default, DHCP is disabled for the BIG-IP system management port on physical devices, and enabled for the BIG-IP system management port on virtual editions. When enabled, DHCP uses UDP ports 67 and 68. On the first boot, the BIG-IP system contacts the DHCP server and obtains a lease for an IP address and a default route for the management port.

Forcing a DHCP lease renewal for the BIG-IP system management port

Ensure that DHCP is enabled on the BIG-IP® system.
Force the renewal of the DHCP lease for an IP address and a default route for the BIG-IP system management port.
  1. Log on to the command-line interface of the BIG-IP system.
  2. At the BASH prompt, type: bigstart restart dhclient
    The dhclient on the BIG-IP system restarts, contacts the DHCP server, and acquires a new lease for the BIG-IP system management port.
The DHCP lease renews automatically at the previously configured interval.
