| LABEL | DESCRIPTION |
| Security | Select whether you want to implement authentication and/or encryption |
| Level | for SNMP communication from this user. Choose: |
|
| • noauth |
|
| SNMP 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. |
|
|
|
| Authenticati | Select an authentication algorithm. MD5 (Message Digest 5) and SHA |
| on | (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 |
|
| block of data. |
|
| • AES - Advanced Encryption Standard is another method for data |
|
| encryption that also uses a secret key. AES applies a |
|

| Apply | Click Apply to save your changes to the Switch’s |
|
| Switch loses these changes if it is turned off or loses power, so use the |
|
| Save link on the top navigation panel to save your changes to the non- |
|
| volatile memory when you are done configuring. |
