Configure SNMP

You can enable SNMP monitoring and configure an agent or agent(s).

Procedure

  1. Log in to the RealPresence Web Suite Services Portal using super admin credentials.
  2. Navigate to Platform Settings > SNMP.
  3. Enable the Enable SNMP Monitoring check box.
  4. Complete the applicable SNMP configuration fields.

    The settings may vary depending on the SNMP version you are using.

    Setting

    Description

    SNMP version

    The version of SNMP (v2c or v3).

    Transport

    This setting specifies the transport protocol to be used.

    This is set to User Datagram Protocol (UDP) and read-only.

    UDP requires fewer network resources and is suited for repetitive, low-priority functions like alarm monitoring, although message delivery is not assured and does not always occur in the order in which messages are sent.

    Port

    The port on which the SNMP agent communicates. This is set to 161 and read-only.

    Community

    This setting is applicable for SNMPv2c only.

    Functions as a global password for accessing SNMP information on the system. An SNMP manager must be configured with the same community string in order to access this system's SNMP information.

    Per SNMP convention, the default community string is “public,” but this must be changed to make the SNMP information more secure.

    Security User

    This setting is applicable for SNMPv3 only.

    Specifies the security name required to access a monitored MIB object.

    Authentication

    This setting is applicable for SNMPv3 only.

    Specifies the authentication protocol. The protocols are used to create unique fixed-sized message digests of a variable- length message.

    Possible values for authentication protocol are MD5 and SHA.

    • MD5 Creates a digest of 128 bits (16 bytes).
    • SHA Creates a digest of 160 bits (20 bytes).

    Both methods include the authentication key with the SNMPv3 packet and then generate a digest of the entire SNMPv3 packet.

    Password (for authentication)

    Confirm Password

    This setting is applicable for SNMPv3 only.

    In the fields below the Authentication selection, enter and confirm the authentication password that is appended to the authentication key before it is computed into the MD5 or SHA message digest.

    Encryption

    This setting is applicable for SNMPv3 only.

    Specifies the privacy protocol for the connection between the RealPresence Web Suite Services Portal and the SNMP manager.

    The Services Portal implements communication with authentication and privacy (the authPriv security level as defined in the User-based Security Model (USM) MIB).

    The possible values for privacy protocol are:
    • Data Encryption Standard (DES) Uses a 56-bit key with a 56-bit salt to encrypt the SNMPv3 packet.
    • Advanced Encryption Standard (AES) Uses a 128-bit key with a 128-bit salt to encrypt the SNMPv3 packet.

    Password (for encryption)

    Confirm Password

    In the fields below the Encryption selection, enter and confirm the encryption password to be appended to the encryption key.

    Location

    Specifies the value to be returned for a standard MIB query to identify the geographical or logical location of the server.

    Contact

    Specifies the value to be returned for a standard MIB query to identify the name or contact information of an administrator who is responsible for the server.

  5. Click Update.
  6. Click Add Agent to configure a notification agent.
  7. Complete the agent configuration fields.

    The agent configuration selections vary depending on the SNMP versions.

    Note: For each notification agent, you must enter the appropriate SNMP version, transport, and notification type for the SNMP manager to which this agent sends notifications.

    Field

    Definition

    SNMP version

    The version of SNMP (v2c or v3).

    Transport

    Select TCP or UDP.

    Port

    The default is 162. You can select a different port if 162 is in use.

    Type

    Select Trap or Inform.

    A trap is an unacknowledged notification; an inform requests acknowledgment of receipt from the SNMP manager.

    This field must be set in accordance with the capabilities of the SNMP manager.

    IP

    The IP address or FQDN of the SNMP manager to which this agent sends notifications.

    Security User

    This setting is applicable for SNMPv3 only.

    • Select either Create New or Use Existing.
    • Select Create New, to select authentication and encryption protocols, with passwords.
    • If you select Use Existing, select a user from the list of previously defined security users.
  8. Click Add.
  9. Repeat the preceding three steps to add another notification agent.
  10. Click Update on the Configure SNMP page.
