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 offered with the 7.6 and newer firmware. The SNMP v3 security is available to a switch that has a
secure connection (SSL must be enabled), 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 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.
The SNMP v3 Manager dialog allows you to turn SNMP v3 security on and off, and to add, display,
remove, and edit an SNMP v3 user:
• To display the SNMP v3 Manager dialog box ( Figure 31 ), open the Switch menu, select SNMP, and
the select SNMP v3 Manager.
• To turn SNMP v3 security on or off, use the SNMP v3 Security option.
• To add SNMP users, click Add to open the SNMP v3 User Editor dialog box ( Figure 32 ), and add an
SNMP v3 user. After configuring the user, click OK to save the settings and close the dialog box.
After SNMP v3 users are configured and saved, they are displayed in the SNMPv3 Users list window in
the SNMP v3 Manager dialog box.
• To display a user's settings, select a user from the list. The selected user's settings are displayed on the
right in the Selected SNMPv3 User area.
• To remove a user from the SNMP v3 Users list, select the user name, and then click Remove.
• To edit a user's configuration, click Edit to open the SNMP v3 User Editor Edit User dialog box and
make the desired changes.
