Problem this snippet solves:

The script takes command line arguments to log into a version 9 BigIP and either show all the pools and members, or enable|disable all of a specified pool's members.

Code :

my $sProtocol = "https";

sub usage()
{

if ( ($sHost eq "") or ($sPort eq "") or ($sUID eq "") or ($sPWD eq "") or (($sPool ne "") and ($desired_pool_state eq "")) )
