====== Driver test: close and reopen ======

===== Rationale =====

Closing and reopening an interface is an uncommon action, and problems are unlikely to be discovered during normal operation.  The ''[[:cmd:ifclose]]'' commands can be used to verify that a card continues to work after being closed and reopened.

===== Test sequence =====

  - Before starting, ensure that system power is off and the network cable is connected to a network which provides a DHCP server.
  - Power on and boot to the iPXE command line.
  - Use ifstat to identify the name of your network interface (hereafter assumed to be ''net0'').
  - Open the interface and initiate a DHCP request using ''[[:cmd:dhcp]] net0''.
  - Verify that the DHCP command completes without an error.
  - Close the interface using ''[[:cmd:ifclose]]''.
  - Reopen the interface and initiate a DHCP request using ''[[:cmd:dhcp]] net0''.
  - Verify that this second DHCP command also completes without an error.
