Threshold for minimum number of nodes in a pool

I'm using perl to get the member active states, and I'm having trouble figuring out how to pass the member_defs argument to the get_member_active_states method. The code samples provided in the SDK only pass simple parameters like strings, but I can't figure out how to pass an IPPortDefinition[] struture.

 

 

Here's what I have been trying:

 

 

my $soap_response = $soap->get_member_active_states ( SOAP::Data->name(pool_name => $poolName), SOAP::Data->name(member_defs => @{member_list})

 

 

@member_list is the result of the getPoolMemberList function in the LocalLBPool.pl example from the SDK.

 

 

Thanks,
