Security Level | Select whether you want to implement authentication and/or encryption for SNMP |
| communication from this user. Choose: |
| • noauth |
| manager. This is equivalent to the Get, Set and Trap Community in SNMP v2c. |
| This is the lowest security level. |
| • auth - to implement an authentication algorithm for SNMP messages sent by |
| this user. |
| • priv - to implement authentication and encryption for SNMP messages sent by |
| this user. This is the highest security level. |
| Note: The settings on the SNMP manager must be set at the same |
| security level or higher than the security level settings on the |
| Switch. |
|
|
Authentication | Select an authentication algorithm. 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 | Specify the encryption method for SNMP communication from this user. You can |
| choose one of the following: |
| • DES - Data Encryption Standard is a widely used (but breakable) method of |
| data encryption. It applies a |
| • AES - Advanced Encryption Standard is another method for data encryption |
| that also uses a secret key. AES applies a |
