Configuring SNMP Agents

SNMP-compliant devices, called agents, store data about themselves in Management Information Bases (MIBs) and return this data to the SNMP managers. See Viewing the KX III MIB for information on viewing the KX III MIB.

KX III supports SNMP logging for SNMP v1/v2c and/or v3. SNMP v1/v2c defines message formats and protocol operations when SNMP logging is enabled. SNMP v3 is a security extension of SNMP that provides user authentication, password management and encryption.

• To configure SNMP agents:

1. Choose Device Settings > Device Services. The Device Service Settings page opens.
2. Provide the following SNMP agent identifier information for the MIB-II System Group objects:
   1. System Name - the SNMP agent's name/device name
   2. System Contact - the contact name related to the device
   3. System Location - the location of the device
3. Select either or both Enable SNMP v1/v2c and Enable SNMP v3. At least one option must be selected. Required
4. Complete the following fields for SNMP v1/v2c (if needed):
   1. Community - the device's community string
   2. Community Type - grant either Read-Only or Read-Write access to the community users

      Note: An SNMP community is the group to which devices and management stations running SNMP belong. It helps define where information is sent. The community name is used to identify the group. The SNMP device or agent may belong to more than one SNMP community.

5. Complete the following fields for SNMP v3 (if needed):
   1. Select Use Auth Passphrase if one is needed. If the Privacy Passphrase is required, the 'Use Auth Passphrase' allows you to have the same passphrase for both without having to re-enter the Auth Passphrase.
   2. Security Name - the username or service account name of the entity communicating with the SNMP agent (up to 32 characters)
   3. Authentication Protocol - the MD5 or SHA authentication protocol used by the SNMP v3 agent
   4. Authentication Passphrase - the passphrase required to access the SNMP v3 agent (up to 64 characters)
   5. Privacy Protocol - if applicable, the AES or DES algorithm used to encrypt PDU and context data
   6. Privacy Passphrase - the passphrase used to access the privacy protocol algorithm (up to 64 characters)
6. Click OK to start the SNMP agent service.

Configure SNMP traps on the Event Management - Settings page, which can be quickly accessed by clicking the SNMP Trap Configuration link. See Configuring SNMP Traps for information on creating SNMP traps and List of KX III SNMP Traps for a list of available KX III SNMP traps.

The events that are captured once an SNMP trap is configured are selected on the Event Management - Destination page. See Configuring Event Management - Destinations.

• To reset to factory defaults:

• Click Reset To Defaults. All items on the page are set back to their defaults.

WARNING: When using SNMP traps over UDP, it is possible for the KX III and the router that it is attached to fall out of synchronization when the KX III is rebooted, preventing the reboot completed SNMP trap from being logged.
