Table 4–1 (Cont.) snmp_request Command Parameters
Parameter Function
"community" The community string to be used in the query. This parameter is case
sensitive. Typically, agents are configured to permit read access to
the community string "public". For accurate interpretation, be sure to
enclose the name in quotation marks (" "). Note that if you do not use
quotation marks, the name is changed to lowercase.
request-type PDU type to send. Can be one of the following SNMP requests:
Get Sends a Get-Request PDU.
GetNext Sends a GetNext-Request PDU.
GetBulk Sends a GetBulk-Request PDU (SNMP Version 2
only).
Set Sends a Set-Request PDU.
variable An object identifier (OID) in ASN.1 notation that is associated with
an object in a MIB. For example:
$ snmp_request host1 "public" getnext -d 1.3.6.1.6.3.1.1.6
data-type Data type of the value. This parameter can be specified for Set
requests. The data types are described in Section 4.1.3.
value The value to which to set the contents of the OID. This parameter is
used for
set requests.
For Set requests, you can specify more than one group of the following:
• variable-name
• data-type
• value
For other requests, you can specify more than one variable name, except when
you specify the
-l or -t flag; these flags are valid only with a GetNext or GetBulk
request, for which only one OID is permitted.
4.1.2 MIB Browser Flags
Flags are specified in UNIX format.
Because flags and data types are case sensitive, you should always enter them in
the case that is specified. If a letter or value is specified as uppercase, you must
enclose it in quotation marks. In general, if you use uppercase letters where
lowercase is specified, the results are unpredictable. For example, the flag
"-v2C"
functions correctly but the flag "-V2c" does not, because the flag character ( v )
must be lowercase.
If you do not specify a flag, or if you specify an invalid flag, a usage message is
displayed. You must place the flags after the
request-type parameter.
Table 4–2 describes the flags for the snmp_request command.
