Note
Except for -l (Counter64), the data types are case sensitive. To preserve
uppercase for display strings and NULL, enclose the value in double
quotation marks. For example, ‘‘–
D ’’ or ‘‘– N ’’.
On OpenVMS Alpha systems, you must specify the value of the -l data type as a
64-bit integer. For example:
$ snmp_trapsnd 0.0 mynode 6 33 100 -h mynode -v2c -
_$ 1.3.6.1.2.1.1.4.0 "l" 1311768467294899695
On OpenVMS VAX systems, you must specify the value of the -l data type as a
16-digit hexadecimal value. For example:
$ snmp_trapsnd 0.0 mynode 6 33 100 -h mynode -v2c -
_$ 1.3.6.1.2.1.1.4.0 "l" 0x1234567890ABCDEF
Note that alphabetic characters are not case sensitive when used with the -l data
type.
For more information about the data types, see RFCs 1155 and 1902.
4.1.4 Command Examples for snmp_request
This section presents several examples of using the snmp_request utility. In the
following snmp_request command examples:
• The valid host name is marley.dec.com .
• The "public" community is type Read, address 0.0.0.0.
• The "address_list" community is type Read and Write, with write access for
the host on which the snmp_request program is running.
• The location has been specified as shown in the following command:
TCPIP> SET CONFIGURATION SNMP -
_TCPIP> /LOCATION=(FIRST="Falcon Building",SECOND="Los Angeles, CA")
• The command responses have been edited for readability.
Examples
1. The following example shows how to retrieve the value of the MIB II variable
sysDescr.0 (1.3.6.1.2.1.1.1.0) . The request is successful because the OID
( variable_name ) provided in the command line exists and is readable. This
OID is returned by the subagent code that resides in the master agent.
$ snmp_request marley.dec.com "public" get 1.3.6.1.2.1.1.1.0
1.3.6.1.2.1.1.1.0 = marley.dec.com AlphaServer 2100 4/200 OpenVMS

2. The following example shows how to retrieve two MIB II variables. This
example is identical to the previous example, except that two OID values are
input and two returned: instance 1 of
ifDescr and hrSystemUptime . Note
that the first value comes from the MIB II subagent (TCPIP$OS_MIBS) and
the second comes from the Host Resources MIB subagent (TCPIP$HR_MIB).
