Simple Network Management Protocol (SNMP) is a set of network protocols designed to allow you to manage and monitor devices on your network.

You can use the SNMP configuration pages in the Embedded Web Server to:

  • Enable or disable Authentication Failure Generic Traps.

  • Enable SNMPv3 to create an encrypted channel for secure printer management.

  • Assign privacy, authentication protocols, and keys to Administrative and key user accounts.

  • Assign read and write access to User accounts.

  • Limit SNMP access to the printer using hosts.

Configuring SNMPv1/v2c

SNMP version 1 (SNMPv1) is the initial implementation of the SNMP protocol. SNMPv1 operates over protocols such as User Datagram Protocol (UDP), IP, and Novell Internet Packet Exchange (IPX).

SNMPv2c includes improvements in performance, confidentiality, and manager-to-manager communications over SNMPv1, however it uses the simple-community based security scheme of SNMPv1.

SNMPv1/v2c uses the following community names:

  • Community Name Read Only: The Community Name Read Only returns the password for the SNMP GET requests to the printer. Applications that obtain information from the printer using SNMP, such as the Embedded Web Server, use this password. The default value is public.

  • Community Name Read/Write: The Community Name Read/Write returns the password for the SNMP SET requests to the printer. Applications that set information on the printer using SNMP use this password. The default value is private.

  • Default TRAP Community Name: The Default TRAP Community Name specifies the default community name for all traps that the printer generates. Individual Trap Community Names that are specified for each trap destination address can override the community name. Ensure that you make each Trap Community Name unique. The default value is SNMP_trap.

    Note: Changes made to the community names for this printer require corresponding changes to GET or SET community name applications using SNMP.

To configure SNMPv1/v2c:

  1. Access the printer's Embedded Web Server and log in as a System Administrator.

  2. Click Connectivity.

  3. In the Protocols area, click SNMP.

  4. For Port, click the toggle button.

  5. For Send Authentication Error Traps, click the toggle button.

  6. Click SNMPv1/v2.

  7. If needed, for Community Name Read Only, type an SNMP GET name.

  8. If needed, for Community Name Read/Write, type an SNMP SET name.

  9. If needed, for Default Trap Community Name, type an SNMP trap name.

  10. In the System Administrator Login ID area, type the login ID for the administrator.

  11. You can set Trap Destinations for LAN1 and Wi-Fi.

    • Click an available field.

    • Select the address type. Options include IPv4, IPv6, or Host Name.

    • For IP Address/Host Name and Port, type the IP address or the network host name for the Trap Destination, then type the port number.

    • For Trap Community Name, type a name.

    • For Traps to Be Received, select the traps that the SNMP manager receives. For each item, enable the toggle button.

    • Click OK.

  12. Click OK.

  13. If prompted to restart the device for changes to take effect, click Restart Now.

Configuring SNMPv3

SNMPv3 is the current standard version of SNMP defined by the Internet Engineering Task Force (IETF). SNMPv3 provides three important security features:

  • Message integrity to ensure that tampering with a packet does not occur during transit

  • Authentication to verify that the message is from a valid source

  • Encryption of packets to prevent unauthorized access

    Notes:

    • Ensure that HTTPS SSL communication is enabled. For details, refer to Configuring HTTP Settings in the Embedded Web Server.

    • To use SNMPv3 in FIPS Mode, enable FIPS 140-2. For details, refer to FIPS 140-2.

Editing SNMPv3 Properties

Note: To change the settings for SNMPv3, first enable HTTPS (SSL) communication. To use SNMPv3 in FIPS mode, first enable FIPS 140-2.

  1. Access the printer's Embedded Web Server and log in as a System Administrator.

  2. Click Connectivity.

  3. In the Protocols area, click SNMP.

  4. For Port, select the toggle button.

  5. Click SNMPv3.

  6. For Enable (Read), select the toggle button.

  7. To enable write access, for Write, select the toggle button.

  8. To enable the system administrator account, for System Administrator Account, select the toggle button.

    Note: When using SNMPv3 in FIPS mode, Message Digest Algorithm is set to SHA-1 and Message Encryption Algorithm is set to AES-128 automatically. To change these options, first disable FIPS mode.

    1. For Message Digest Algorithm, select MD5 or SHA-1.

    2. Type the authentication password, then retype the password.

    3. For Message Encryption Algorithm, select DES or AES-128.

    4. Type the encryption password, then retype the password.

  9. To enable the print drivers account, for Print Drivers Account, select the toggle button.

    Note: When using SNMPv3 in FIPS mode, the Message Digest Algorithm and Message Encryption Algorithm options are set automatically. To change these options, first disable FIPS mode.

  10. To configure trap destinations, click any available trap destination field, then configure as needed.

    • For Type, click IPv4, IPv6, or Host Name.

    • For IP Address: Port or Host Name: Port, type the IP address or host name.

    • Click User Name, then select an option.

    • For Traps to Be Received, to enable specific traps, for each trap, select the toggle button.

    • Click OK.

  11. Click OK.

  12. If prompted to restart the device for changes to take effect, click Restart Now.
