Dell Force10 S4820T S4820T Configuration Guide - Page 886

www.dell.com | support.dell.com Configure Simple Network Management Protocol Note: The configurations in this chapter use a UNIX environment with net-snmp version 5.4. This is only one of many RFC-compliant SNMP utilities you can use to manage your Dell Force10 system using SNMP. Also, these configurations use SNMP version 2c. Configuring SNMP version 1 or version 2 requires only a single step: 1. Create a community. See page 887. Configuring SNMP version 3 requires you to configure SNMP users in one of three methods. 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). 886 | Simple Network Management Protocol (SNMP)
