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 by a combination of authenticating and encrypting packets over
the network. SNMP v3 security is an additional layer of security offered with the8.0
firmware. The SNMP v3 security is available to a switch that has a secure
connection, and can only be configured on the entry switch. The security features
provided in SNMPv3 are:

Message integrity—ensuring that a packet has not been tampered with
during transit.

Authentication—determining the message is from a valid source.

Encryption—scrambling the contents of a packet to prevent it from being
seen by an unauthorized source.
The SNMP v3 Manager dialog box allows you to add, remove, and edit an SNMP
v3 user. To display the SNMP v3 Manager dialog box (
Figure 3-12 ) on the Switch
menu, click SNMP , and click SNMP v3 Manager . The SNMP v3 Security option
allows you to turn SNMP v3 security on or off.
Click Add to view the SNMP v3 User Editor dialog box ( Figure 3-13 ), and add an
SNMP v3 user. After SNMP v3 users are configured and saved, they are
displayed on the SNMPv3 Users list window on the SNMP v3 Manager dialog box.
Select a user from the list, and that user’s settings are displayed on the right in the
Selected SNMPv3 User area. The
Remove and Edit buttons become active when
you select a user from the SNMP v3 Users list. Click Remove to delete the
selected user. Click Edit to view the SNMP v3 User Editor Edit User dialog box in
which to change the selected user's configuration.
