I'm a little stuck... Click here to teach me more about this clue!

'to get this protocol' is the definition.
'entente cordiale' can be an answer for 'protocol' (type of political relationship or protocol). I am not certain of the remainder of the definition.

'rearrange a nine-letter code' is the wordplay.
'rearrange' indicates an anagram (I've seen this in other clues).
'a'+'nine'+'letter'+'code'='aninelettercode'
'aninelettercode' with letters rearranged gives 'ENTENTE CORDIALE'.

Can you help me to learn more?
