Summary
It is necessary to record the new passphrases loaded into the Aprisa SR+ radios and then load the
passphrases into the SNMP manager. There is a separate passphrase for the two supported forms of
authentication (MD5 and SHA1) only as well as the two forms of authentication used in combination the
two forms of encryption (DES and AES). It is vital to change all passphrases even if the depreciated
mechanism are not used (MD5 and DES) otherwise an attacker could still use the default passphrases.
