A maximum of 16 characters. • read view-name - (Optional) Enter the name of a read-only view. A maximum of 32 characters maximum. • write view-name - (Optional) Enter the name of a read-write view.

Defaults Not configured Command Mode CONFIGURATION Usage Information Use this command to set up the access privileges for a group of SNMP users. Configure the security level for receiving SNMP messages. Specify read-only, read-write, and/or notification access to the SNMP agent. To configure an SNMPv3 user's authentication and privacy settings, use the snmp-server user command. Enter an access acl-name value to limit access to the SNMP agent to only ACL-allowed users. A read-view provides read-only access to the SNMP agent. A read-write view allows read-write access. A notifyview allows SNMP notifications to be sent to group members. Supported on the MX9116n and MX5108n switches in both Full Switch mode starting in release 10.4.2.0. Also supported in SmartFabric mode starting in release 10.5.0.1.

Syntax Parameters snmp-server host {ipv4-address | ipv6-address} {informs version version-number | traps version version-number | version version-number} [snmpv3-securitylevel] [community-name] [udp-port port-number] [dom | entity | envmon | lldp | snmp] • ipv4-address | ipv6-address - Enter the IPv4 or IPv6 address of the SNMP host. • informs - Send inform messages to the SNMP host. • traps - Send trap messages to the SNMP host. • version version-number - Enter the SNMP security model used to send traps or informs to the SNMP host - 1, 2c, or 3. All security models support traps; only 2c and 3 support informs. To send only SNMP notifications, enter only a version-number; do not enter informs or traps. For SNMPv3 traps and informs, enter the security level: ○ noauth - (SNMPv3 only) Send SNMPv3 traps without user authentication and privacy encryption. ○ auth - (SNMPv3 only) Include a user authentication key for SNMPv3 messages sent to the host: ▪ md5 - Generate an authentication key using the Message Digest Algorithm (MD5) algorithm. ▪ sha - Generate an authentication key using the Secure Hash Algorithm (SHA) algorithm.
