SNMP v3 Security

Simple Network Management Protocol Version 3 (SNMPv3) is an interoperable
standards-based protocol for network management. SNMPv3 provides secure
access to devices using a combination of authenticating and encrypting packets
over the network. SNMP v3 security is an additional layer of security. The SNMP
v3 security is available on a secure (SSL) entry switch. The security features
provided in SNMPv3 are:

Message integrity—ensuring that a packet has not been tampered with
during transit

Authentication—determining that the message is from a valid source

Encryption—scrambling the contents of a packet to prevent it from being
seen by an unauthorized source
You configure SNMP v3 security in the SNMP v3 Manager dialog box
