access-type

Usage
Use this command to enable or disable the re-authentication feature, which instructs the SGSN to retry
authentication with another RAND in situations where failure of the first authentication has occurred. To
address the introduction of new SIM cards, for security reasons a systematic "last chance" authentication retry
with a fresh Authentication Vector is needed, particularly in cases where there is an SRES mismatch at
authentication.
