SNMP Basic
You can configure SNMP contact and trap receiver settings to allow events to be reported to an SNMP entity in the SNMP Basic page.
Traps are messages sent by an SNMP entity that indicate the occurrence of an event. The default system configuration does not include SNMP traps.
RiOS 7.0 and later provides support for these SNMP versions:
•  Version 1
•  Version 2c
•  SNMP v3, that provides authentication through the User-based Security Model (USM).
•  View-Based Access Control Mechanism (VACM), that provides richer access control.
•  SNMP v3 authentication using AES 128 and DES encryption privacy.
The SNMP page contains the following groups of settings:
•  SNMP Server Settings
•  Adding a New Trap Receiver
SNMP Server Settings
Complete the configuration as described in this table.
Control
Description

(Appears only when you select v3). Optionally, select either Supply a Password or Supply a Key to use while authenticating users.
Authentication Protocol
(Appears only when you select v3). Select an authentication method from the drop-down list:
•  MD5 - Specifies the Message-Digest 5 algorithm, a widely used cryptographic hash function with a 128-bit hash value. This is the default value.
•  SHA - Specifies the Secure Hash Algorithm, a set of related cryptographic
Password/Password Confirm
(Appears only when you select v3). Specify a password. The password must have a minimum of eight characters. Confirm the password in the Password Confirm text box.
Security Level
(Appears only when you select v3). Determines whether a single atomic message exchange is authenticated. Select one of these levels from the drop-down list:
•   No Auth - Does not authenticate packets and does not use privacy. This is the default setting.
•  Auth - Authenticates packets but does not use privacy.
•  AuthPriv - Authenticates packets using AES 128 and DES to encrypt messages for privacy.
Note: A security level applies to a group, not to an individual user.
Community
