monitor and control network devices.

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.

Security Level

When SNMPv3 is in use, it is necessary to choose the security level. Use the drop down

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.
