Chapter 37 Access Control Table 162 Management > Access Control > SNMP (continued) LABEL Get Community DESCRIPTION Enter the Get Community string, which is the password for the incoming Get- and GetNext- requests from the management station. Set Community The Get Community string is only used by SNMP managers using SNMP version 2c or lower. Enter the Set Community, which is the password for incoming Set- requests from the management station. Trap Community The Set Community string is only used by SNMP managers using SNMP version 2c or lower. Enter the Trap Community string, which is the password sent with each trap to the SNMP manager. Trap Destination Version IP Port Username The Trap Community string is only used by SNMP managers using SNMP version 2c or lower. Use this section to configure where to send SNMP traps from the Switch. Specify the version of the SNMP trap messages. Enter the IPv4 or IPv6 addresses of up to four managers to send your SNMP traps to. Enter the port number upon which the manager listens for SNMP traps. Enter the username to be sent to the SNMP manager along with the SNMP v3 trap. User Information Note: This username must match an existing account on the Switch (configured in the Management > Access Control > Logins screen). Use this section to configure users for authentication with managers using SNMP v3. Index Username Security Level Note: Use the username and password of the login accounts you specify in this section to create accounts on the SNMP v3 manager. This is a read-only number identifying a login account on the Switch. This field displays the username of a login account on the Switch. Select whether you want to implement authentication and/or encryption for SNMP communication from this user. Choose: • noauth: to use the username as the password string to send to the SNMP manager. This is equivalent to the Get, Set and Trap Community in SNMP v2c. This is the lowest security level. • auth: to implement an authentication algorithm for SNMP messages sent by this user. • priv: to implement authentication and encryption for SNMP messages sent by this user. This is the highest security level. Note: The settings on the SNMP manager must be set at the same security level or higher than the security level settings on the Switch. Authentication Select an authentication algorithm. MD5 (Message Digest 5) and SHA (Secure Hash Algorithm) are hash algorithms used to authenticate SNMP data. SHA authentication is generally considered stronger than MD5, but is slower. Privacy Specify the encryption method for SNMP communication from this user. You can choose one of the following: Apply Cancel • DES - Data Encryption Standard is a widely used (but breakable) method of data encryption. It applies a 56-bit key to each 64-bit block of data. • AES - Advanced Encryption Standard is another method for data encryption that also uses a secret key. AES applies a 128-bit key to 128-bit blocks of data. Click Apply to save your changes to the Switch's run-time memory. The Switch loses these changes if it is turned off or loses power, so use the Save link on the top navigation panel to save your changes to the non-volatile memory when you are done configuring. Click Cancel to begin configuring this screen afresh. VES1724-56 User's Guide 343
