| SNMPv2 – Specifies that SNMP version 2 will be used. The SNMP v2 supports both |
|
| centralized and distributed network management strategies. It includes improvements in |
|
| the Structure of Management Information (SMI) and adds some security features. |
|
| SNMPv3 – Specifies that SNMP version 3 will be used. SNMP v3 provides secure access |
|
| to devices through a combination of authentication and encrypting packets over the |
|
| network. SNMP v3 adds: |
|
| • Message integrity − ensures that packets have not been tampered with during |
|
| transit. |
|
| • Authentication − determines if an SNMP message is from a valid source. |
|
| • Encryption − scrambles the contents of messages to prevent it being viewed by |
|
| an unauthorized source. |

|
| menu to select from the following: |
|
| noauth_nopriv − Specifies that there will be no authorization and no encryption of packets |
|
| sent between the Switch and a remote SNMP manager. |
|
| auth_nopriv − Specifies that authorization will be required, but there will be no encryption |
|
| of packets sent between the Switch and a remote SNMP manager. |
|
| auth_priv − Specifies that authorization will be required, and that packets sent between the |
|
| Switch and a remote SNMP manger will be encrypted. |
