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 doesn’t include SNMP traps.
RiOS 7.0 and later provide support for these SNMP versions:
•  SNMPv1
•  SNMPv2
•  SNMPv3, which provides authentication through the User-based Security Model (USM).
•  View-Based Access Control Mechanism (VACM), which provides richer access control.
•  SNMPv3 authentication using AES 128 and DES encryption privacy.
The SNMP page contains these groups of settings:
•  SNMP server settings
•  Adding a new trap receiver
SNMP server settings
Complete the configuration as described in this table.
Control
Description
Enable SNMP Traps
Enables event reporting to an SNMP entity.
System Contact
Specify the username for the SNMP contact.
System Location
Specify the physical location of the SNMP system.
Read-Only Community String
Specify a string to identify the read-only community: for example, Read-only.
Community strings can’t contain the # (hash) value.
Adding a new trap receiver
Complete the configuration as described in this table.
Control
Description
Add New Trap Receiver
Displays the controls for configuring new trap receivers.
Receiver
Specify the hostname, IPv4 or IPv6 address.
For IPv6 specify an IP address using this format: eight 16-bit hexadecimal strings separated by colons, 128-bits. For example:
2001:38dc:0052:0000:0000:e9a4:00c5:6282
You don’t need to include leading zeros. For example:
2001:38dc:52:0:0:e9a4:c5:6282
You can replace consecutive zero strings with double colons (::). For example:
2001:38dc:52::e9a4:c5:6282
Destination Port
Specify the destination port.
Receiver Type
Select SNMPv1, v2c, or v3 (user-based security mode) from the drop-down list.
Remote User
(Appears only when you select 3). Specify a remote username.
Authentication
(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 - Doesn’t authenticate packets and doesn’t use privacy. This is the default setting.
•  Auth - Authenticates packets but doesn’t 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
Specify the SNMP community name.
Enable Receiver
Enables the new trap receiver.
Add
Adds the new configuration to the Trap Receiver list.
Remove Selected
Select the check box next to the name and click Remove Selected.
