method of data encryption. It applies a 56-bit key to each 64-bit block
of data.
• AES - Advanced Encryption Standard is another method for data
encryption that also uses a secret key. AES applies a 128-bit key to
128-bit blocks of data.

group. SNMP managers in one group are assigned common access rights
to MIBs. Specify in which SNMP group this user is.
admin - Members of this group can perform all types of system
configuration, including the management of administrator accounts.
readwrite - Members of this group have read and write rights, meaning
that the user can create and edit the MIBs on the Switch, except the user
account and AAA configuration.
readonly - Members of this group have read rights only, meaning the
user can collect information from the Switch.
