See Setting Up User-based Security (SNMPv3). Related Configuration Tasks The following list contains configuration tasks for SNMP: • Managing Overload on Startup • Read Managed Object Values • Write Managed Object Values • Subscribe to Managed Object Value Updates using SNMP • Copy Configuration Files Using SNMP • Manage VLANs using SNMP • Enable and Disable a Port using SNMP • Fetch Dynamic MAC Entries using SNMP • Deriving Interface Indices • Monitor Port-channels Important Points to Remember • Typically, 5-second timeout and 3-second retry values on an SNMP server are sufficient for both LAN and WAN applications. If you experience a timeout with these values, increase the timeout value to greater than 3 seconds, and increase the retry value to greater than 2 on your SNMP server. • User ACLs override group ACLs. Setting up SNMP As previously stated, FTOS supports SNMP version 1 and version 2 which are community-based security models. The primary difference between the two versions is that version 2 supports two additional protocol operations (informs operation and snmpgetbulk query) and one additional object (counter64 object). SNMP version 3 (SNMPv3) is a user-based security model that provides password authentication for user security and encryption for data security and privacy. Three sets of configurations are available for SNMP read/write operations: no password or privacy, password privileges, password and privacy privileges A maximum of 16 users can be configured even if they are in different groups. 946 | Simple Network Management Protocol (SNMP)
