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.
The 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 retrieve values in Read-Only mode. Read-write access is not supported.
22:31:23: %RPM1-P:CP %SNMP-6-SNMP_WARM_START: Agent Initialized - SNMP WARM_START.
To create an SNMP community:
• Choose a name for the community.
CONFIGURATION mode
snmp-server community name ro
Example of Creating an SNMP Community

Setting Up User-Based Security (SNMPv3)
When setting up SNMPv3, you can set users up with one of the following three types of conguration 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 conguration. Users must have a group and prole 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.
• Congure the user with view privileges only (no password or privacy privileges).
CONFIGURATION mode
snmp-server user name group-name 3 noauth
• Congure 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
• Congure an SNMPv3 view.
CONFIGURATION mode
snmp-server view view-name oid-tree {included | excluded}
NOTE: To give a user read and write view privileges, repeat this step for each privilege type.
• Congure the user with an authorization password (password privileges only).
CONFIGURATION mode
snmp-server user name group-name 3 noauth auth md5 auth-password
• Congure an SNMP group (password privileges only).
CONFIGURATION mode
snmp-server group groupname {oid-tree} auth read name write name
