iRules command 'GTP::ie get value' incorrectly decodes Serving-Network field, putting the least significant digit of mobile network codes (MNC) value before the other two.
The operation returns results in which the least significant digit is inserted before the other two, resulting in incorrect data being returned.
Using the iRule command 'GTP::ie get value' to retrieve the Serving-Network field from a GTP message (the iRule construction: GTP::ie get value -message $gtp_message 83).
None.
The iRule command 'GTP::ie get -message $gtp_message 83' that retrieves the Serving-Network now returns the correctly ordered, three-digit values for mobile country codes (MCC) and mobile network codes (MNC) as a two-element list: {{<MCC> <MNC>} <optional data>}, where the first element is another list containing actual MCC and MNC values, while the second element is optional binary data which follows MCC and MNC. It is the same format as used for ULI field decoding.
