This page describes how to configure VX for Simple Network Management Protocol (SNMP) monitoring. SNMP is UDP-based network protocol for monitoring network devices. SNMP can be configured using VXbuilder or the Command Line Interface.

For information on what SNMP MIBs and Traps are supported by VX, see SNMP MIBs and Traps Supported by VX.

Configuring SNMP using VXbuilder

In order to configure the VX system for SNMP monitoring, you must first configure SNMP Community names, set SNMP Trap to receive SNMP messages, pick an Ethernet Adapter on which to enable SNMP and then set the SNMP identifiers for the Ethernet Adapter.

To Configure SNMP Community Names

  1. In the VXbuilder configuration tree, select node-root > General on the settings tree, then double click inside the General Settings panel on the right.
  2. Under the SNMP section, enter the Read Community Name and Trap Community Name.
  3. Enable MIB-II Support by checking the box in the SNMP section.

For more information about SNMP Community configuration, see Managing General Settings.

To Set the SNMP Trap Configuration

  1. In VXbuilder, select node-root > Logging > SNMP Traps. The right-pane displays the SNMP Traps view.
  2. Double-click the Item/Address line to add an address. VX displays the Edit Trap Server dialog.

    VX logs events and logs are sent as traps to the configured IP address. If multiple IP addresses are configured, traps are dispatched to each one of them.

  3. In the IP Address/FQDN field enter the IP address or Fully Qualified Domain Name (FQDN) to which the new SNMP traps should be sent.
  4. Click the Enable SNMPv3 check box to enable. Valid selection: Uncheck (Trap User dropdown list is disabled and VX sends SNMPv2 traps on that trap server) or Check (Trap user dropdown list is enabled).
  5. From the Trap User drop down box, select the Trap User to which the VX sends traps on that trap server.

    To send SNMPv3 traps with authentication and privacy for a specific trap server, ensure the following:

    • Enable SNMPv3 checkbox must be enabled
    • User selected from the Trap User drop down list must be valid
    • Transport Type is configured as UDP in the Edit User configuration (refer to Managing User Information.

For more information on the types of traps that the VX system reports, see SNMP MIBs and Traps Supported by VX. For more information about the SNMP Traps setting, see SNMP Traps.

Next, set the Ethernet Adapter parameters for SNMP.

The SNMP standard MIBs 'ifName' and 'ifAlias' are user configured values and are configured as part of the Ethernet adapter configuration. VX uses the system internal description for 'ifDesc' value if left empty in the configuration. Setting a value for 'Desc' in the Ethernet adapter configuration overrides the system internal description.

  • Ethernet adapter entries in VX configuration are used to set values for 'ifName', 'ifAlias' and 'ifDesc' MIB of the 'ifTable' and 'ifXTable'

To Set the Ethernet Adapter Configuration for SNMP

  1. In VXbuilder, expand the configuration tree to node-root > Networking > Ethernet Adapters > Ethernet Adapter #x, and then double click the Ethernet Adapter #x entry.
  2. In the Edit Adapter dialog, in the Desc field, enter a description to be used in the 'ifDesc' MIB of the of the 'ifTable' and 'ifXTable'.
  3. In the SNMP Name field, enter a description to be used in the 'ifName' MIB of the of the 'ifTable' and 'ifXTable'.
  4. In the SNMP Alias field, enter a description to be used in the 'ifAlias' MIB of the of the 'ifTable' and 'ifXTable'.

For more information editing the Ethernet Adapter configuration, see Ethernet Adapters.

Finally, you must edit the IP interface of this adapter to enable SNMP.

To Enable SNMP Monitoring on an Ethernet Adapter

  1. In VXbuilder, select node-root > Networking > Ethernet Adapters > Ethernet Adapter #x.
  2. In the Interfaces for Ethernet Adapter #1 panel on the right, double click an entry.
  3. In the Edit IP Interface dialog, enable the SNMP option by selecting Yes.

For more information about modifying IP Interfaces, see Setting Up IP Interfaces.

Configuring SNMP using the CLI

In order to configure the VX system for SNMP monitoring, you must first configure SNMP Community names, set SNMP Trap to receive SNMP messages, pick an Ethernet Adapter on which to enable SNMP and then set the SNMP identifiers for the Ethernet Adapter.

To Access the VX Command Line Interface

  1. Connect to the VX system using a telnet-compatible application. (more information...)
  2. Set the interface to command mode using the enable command:

    vx-node1> enable
    Password: *****
    vx-node1#
    

The CLI prompt should now end in a # instead of >.

Using the snmp configure command, follow the tasks in this step to configure SNMP.

To Configure SNMP Using the CLI

  1. Switch to configuration mode:

    vx-node1# config
    
  2. Set the SNMP Community Name and SNMP Trap Community Name using the snmp read-community command:

    vx-node1/config# snmp read-community public
    
  3. Set the SNMP System Contact using the snmp system-contact command:

    vx-node1/config# snmp system-contact admin
    
  4. Optionally, enable MIB-II Support using the snmp mib-ii command:

    vx-node1/config# snmp mib-ii enable
    
  5. Set the SNMP System Location using the snmp system-location command:

    vx-node1/config# snmp system-location anywhere
    
  6. Set the SNMP Trap Destination with one or more SNMP server IP address using the snmp trap command:

    vx-node1/config# snmp trap add 1.1.2.1
    

To Configure the Ethernet Interface

Using the configure command adapter > ethernet adapter mode > interface syntax, follow the tasks in this step to configure the Ethernet Interface.

  1. Change to Ethernet adapter configuration mode using the config command:

    vx-node1#config eth adapter interface
    
  2. Select an IP interface using the interface command:

    vx-node1/config/eth1#interface ip 1
    
  3. Enable SNMP on this IP interface using the snmp command:

    vx-node1/config/eth1/ip1#snmp enable
    

Next, using the configure command adapter, follow the tasks in this step to configure the Ethernet Adapter.

Ethernet adapter entries in VX configuration are used to set values for 'ifName', 'ifAlias' and 'ifDesc' MIB of the 'ifTable' and 'ifXTable'.

To Configure the Ethernet Adapter

  1. Select an Ethernet adapter using the adapter command

    vx-node1# adapter eth1
    vx-node1/config/eth1#
    
  2. Set the description for the adapter:

    vx-node1/config/eth1# desc purposeOfAdaptor
