ProSafe® Gigabit L3 Managed Stackable Switches Software Administration Manual To configure SNMPv3 settings for the user account: 1. Use User Name to specify the user account to be configured. 2. SNMP v3 Access Mode - Indicates the SNMPv3 access privileges for the user account. The admin account always has 'Read/Write' access, and all other accounts have 'Read Only' access. 3. Use Authentication Protocol to specify the SNMPv3 Authentication Protocol setting for the selected user account. The valid Authentication Protocols are None, MD5 or SHA: • If you select None, the user will be unable to access the SNMP data from an SNMP browser. • If you select MD5 or SHA, the user login password will be used as the SNMPv3 authentication password, and you must therefore specify a password, and it must be eight characters long. 4. Use Encryption Protocol to specify the SNMPv3 Encryption Protocol setting for the selected user account. The valid Encryption Protocols are None or DES: • If you select the DES Protocol you must enter a key in the Encryption Key field. • If None is specified for the Protocol, the Encryption Key is ignored. 5. Encryption Key - If you selected DES in the Encryption Protocol field enter the SNMPv3 Encryption Key here, otherwise, this field is ignored. Valid keys are 0 to 15 characters long. The Apply checkbox must be checked in order to change the Encryption Protocol and Encryption Key. 6. Click CANCEL to cancel the configuration on the screen. Resets the data on the screen to the latest value of the switch. 7. Click APPLY to send the updated configuration to the switch. Configuration changes take effect immediately. LLDP The IEEE 802.1AB-defined standard, Link Layer Discovery Protocol (LLDP), allows stations on an 802 LAN to advertise major capabilities and physical descriptions. This information is viewed by a network manager to identify system topology and detect bad configurations on the LAN. From the LLDP link, you can access the following pages: • LLDP on page 103 • LLDP-MED on page 113 LLDP is a one-way protocol; there are no request/response sequences. Information is advertised by stations implementing the transmit function, and is received and processed by stations implementing the receive function. The transmit and receive functions can be enabled/disabled separately per port. By default, both transmit and receive are disabled on all ports. The application is responsible for starting each transmit and receive state machine appropriately, based on the configured status and operational state of the port. 102 | Chapter 2.
