826 | Simple Network Management Protocol (SNMP)
www.dell.com | support.dell.com
• Dell networking OS supports up to 16 trap receivers.
• The Dell networking OS implementation of the sFlow MIB supports sFlow configuration via SNMP
sets.
• SNMP traps for STP and MSTP state changes are based on BRIDGE MIB (RFC 1483) for STP and
IEEE 802.1 draft ruzin-mstp-mib-02 for MSTP.
Configuring Simple Network Management Protocol
Configuring SNMP version 1 or version 2 requires only a single step:
1. Create a community. See page 827.
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
• Subscribing to Managed Object Value Updates using SNMP
• Copying Configuration Files Using SNMP
• Managing VLANs using SNMP
• Enabling and Disabling a Port using SNMP
• Fetching Dynamic MAC Entries using SNMP
• Monitoring 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.
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 Networking system using
SNMP. Also, these configurations use SNMP version 2c.
