SNMP community is a group of SNMP agents and managers that are allowed to interact. Communities are
necessary to secure communication between SNMP managers and agents; SNMP agents do not respond to
requests from management stations that are not part of the community.
Dell Networking OS enables SNMP automatically when you create an SNMP community and displays the
following message. You must specify whether members of the community may only retrieve values (read), or
retrieve and alter values (read-write).
22:31:23: %STKUNIT0-P:CP %SNMP-6-SNMP_WARM_START: Agent Initialized - SNMP
WARM_START.
To choose a name for the community you create, use the following command.
• Choose a name for the community.
CONFIGURATION mode
snmp-server community name {ro | rw}

Setting Up User-Based Security (SNMPv3)
When setting up SNMPv3, you can set users up with one of the following three types of configuration for
SNMP read/write operations.
Users are typically associated to an SNMP group with permissions provided, such as OID view.
• noauth — no password or privacy. Select this option to set up a user with no password or privacy
privileges. This setting is the basic configuration. Users must have a group and profile that do not require
password privileges.
• auth — password privileges. Select this option to set up a user with password authentication.
• priv — password and privacy privileges. Select this option to set up a user with password and privacy
privileges.
To set up user-based security (SNMPv3), use the following commands.
• Configure the user with view privileges only (no password or privacy privileges).
CONFIGURATION mode
snmp-server user name group-name 3 noauth
• Configure an SNMP group with view privileges only (no password or privacy privileges).
CONFIGURATION mode
snmp-server group group-name 3 noauth auth read name write name
• Configure an SNMPv3 view.
