Read/Write - The SNMP administrator has read and write rights, meaning that the
user can create and edit the MIBs on the NWA1121-NI.
Read Only - The SNMP administrator has read rights only, meaning the user can collect
information from the NWA1121-NI.
Authentication
Protocol Select an authentication algorithm used for SNMP communication with the SNMP
administrator.
MD5 (Message Digest 5) and SHA (Secure Hash Algorithm) are hash algorithms used
to authenticate SNMP data. SHA authentication is generally considered stronger than
MD5 , but is slower.
Privacy Protocol Specify the encryption method used for SNMP communication with the SNMP
administrator.
DES - Data Encryption Standard is a widely used (but breakable) 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.
