Configuring SNMP 

This section describes how to configurea host-managed DTC to act as an
SNMP(Simple Network Management Protocol) agent.For PC-based DTC
management, refer to the Using HP OpenView DTC Manager manual.

Configuring SNMP Authorization Filters 

To configure SNMP authorization filters, access the SNMP Authorization
Filter Configuration screen within NMMGR. This screen can be accessed by
pressing [F4], the [Config SNMP] function key at the DTC Configuration
screen.  See the beginning of this chapter to find out how to access the
[Config SNMP] function key.  (Refer to Figure 5-5  for an example of a
DTC Configuration screen for a DTC 72MX.) The screen can also be accessed
by pressing the [Go To Filter] key at the SNMP MIB Configuration screen
or the SNMP Trap Destination Configuration screen.

The SNMP Authorization Filter Configuration screen for host-based
management is shown below, in Figure 8-4 .  You can configure
authorization filters for up to five SNMP managers. 


          Figure 8-4.  SNMP Authorization Filter Screen 

The "DTC Name" field is a read-only field which indicates the SNMP
configuration is for that specific DTC.

   1.  Enter the IP address of the SNMP manager in the "IP Address"
       field.

       The IP address can be any valid individual IP address, or enter
       *.*.*.* or @.@.@.@ to indicate that any IP address is allowed
       access.

   2.  Enter the name of the SNMP community to which the DTC belongs in
       the "Community Name" field.

       The community name is a maximum of 80 alphanumeric characters and
       is case-sensitive.

   3.  The "Read Only" field defines the access mode to MIB objects.
       Enter a Y to restrict the SNMP manager to read-only access; enter
       an N if MIB objects can be modified by the SNMP manager.

       If two or more managers are configured with the same community
       name, the "Read Only" field must be the same for each manager.

   4.  The "MIB View" field defines which SNMP parameters can be accessed
       by the SNMP manager.  Enter 1 for DTC MIB or 2 for MIB-II.

       If two or more managers are configured with the same community
       name, the "MIB View" field must be the same for each manager.

   5.  After you have configured the authorization filters, press the
       [Save Data] function key.

       Note:  Partially-configured filters are not acceptable.

   6.  Press the [Go To MIB] key to configure SNMP MIB parameters or the
       [Go To Trap] key to configure trap destinations.  If you have
       completed configuration of MIB parameters and trap destinations,
       press the [Prior Screen] key to return to the DTC Configuration
       screen, or press [Validate DTS/LINK] to validate your
       configuration if you have completed configuration for your DTCs.

Configuring SNMP MIB Parameters 

To configure SNMP MIB parametersand enable/disable authentication
traps,access the SNMP MIB Configuration screen.This screen can be
accessed by pressing the [Go To MIB] key at the SNMP Authorization Filter
Configuration screen or the SNMP Trap Destination Configuration screen.

The SNMP MIB Configuration screen for host-based management is shown
below, in Figure 8-5 .


          Figure 8-5.  SNMP MIB Configuration Screen 

The "DTC Name" field is a read-only field which indicates the SNMP
configuration is for that specific DTC.

   1.  The "SysContact", "SysName", and "SysLocation" fields provide
       optional information about the DTC such as contact person, the
       DTC's fully-qualified name and physical location.

       Each field allows text up to 256 alphanumeric characters and is
       case sensitive.

   2.  The "Enable authentication traps" field indicates whether the SNMP
       agent should generate authentication failure traps.  Enter Y to
       enable trap generation (see the section on "Configuring Trap
       Destinations"); enter N to disable it.

   3.  After you have configured the MIB parameters, press the [Save 
       Data] function key.

   4.  Press the [Go To Trap] key to configure trap destinations or the
       [Go To Filter] key to configure authorization filters.  Or, if you
       have completed configuration for your DTCs, press [Validate 
       DTS/LINK] to validate your configuration.

Configuring Trap Destinations 

To specify the SNMP managers that will receive any SNMP error messages
generated by the DTC, access the SNMP Trap.Destination Configuration
screen.This screen can be accessed by pressing the [Go To Trap] key at
the SNMP MIB Configuration screen or SNMP Authorization Filter
Configuration screen.

The SNMP Trap Destination Configuration screen for host-based management
is shown below, in Figure 8-6 .  You can configure up to ten IP
addresses for trap destinations.


          Figure 8-6.  SNMP Trap Destination Screen 

The "DTC Name" field is a read-only field which indicates the SNMP
configuration is for that specific DTC.

   1.  Enter the IP address of the SNMP manager in the "IP Address"
       field.

       The IP address must be a valid individual IP address; the global
       definition of IP addresses, "*.*.*.*" or "@.@.@.@", is not valid
       for this screen.

       Note:  Only DTC MIBs can send error trap information.  Make sure
       that all IP addresses entered have MIB View = "1" (see SNMP
       Authorization Filter Configuration screen).

   2.  After you have configured the trap destinations, press the [Save 
       Data] function key.

   3.  Press the [Go to Filter] key to configure authorization filters or
       the [Go To MIB] key to configure MIB parameters.  Or, if you have
       completed configuration for your DTCs, press [Validate DTS/LINK] 
       to validate your configuration.
