Configuration Task List for SNMP
Configuring SNMP version 1 or version 2 requires a single step.
NOTE: The configurations in this chapter use a UNIX environment with net-snmp version 5.4. This
environment is only one of many RFC-compliant SNMP utilities you can use to manage your Dell
Networking system using SNMP. Also, these configurations use SNMP version 2c.
• Creating a Community
Configuring SNMP version 3 requires configuring SNMP users in one of three methods. Refer to Setting
Up User-Based Security (SNMPv3).
Related Configuration Tasks
• Managing Overload on Startup
• Reading Managed Object Values
• Writing Managed Object Values

• Manage VLANs Using SNMP
• Enabling and Disabling 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 seconds on your SNMP server.
• User ACLs override group ACLs.
Set up SNMP
As previously stated, Dell Networking OS supports SNMP version 1 and version 2 that 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.
You can configure a maximum of 16 users even if they are in different groups.
