Server configuration using conditional evaluation

[glenn.satchell at uniq.com.au]

The dhcp-eval man page shows the syntax for switch(), binary-to-ascii() 
and substring(). It's important that you use the right length for the 
substring() so that it can do the binary-to-ascii() correctly. It might 
be that the value from the switch is null or not calculated as you 
expected.

switch (binary-to-ascii(16, 32, ".", substring(option dhcp6.ia-na, 0, 
4)))

Here the substring() is taking the 4 bytes starting at offset 0 - the 
first four bytes.

Then binary-to-ascii is treating that as a 32 bit number and displaying 
it as two 16 bit numbers with a "." in  between. Do you know what the 
dhcp6.ia-na is that is being sent so you can manually confirm the 
function is doing what you expect?

Glenn
