AES Privacy Protocol for SNMPv3 Users
Cisco UCS uses Advanced Encryption Standard (AES) as one of the privacy protocols for SNMPv3 message
encryption and conforms with RFC 3826.
The privacy password, or priv option, offers a choice of DES or 128-bit AES encryption for SNMP security
encryption. If you enable AES-128 configuration and include a privacy password for an SNMPv3 user, Cisco
UCS Manager uses the privacy password to generate a 128-bit AES key. The AES privacy password can have
a minimum of eight characters. If the passphrases are specified in clear text, you can specify a maximum of
64 characters.
