snmpbulkwalk - communicates with a network entity using SNMP BULK Requests.
28
[APPLICATION OPTIONS] [COMMON OPTIONS] [OID]
31
is an SNMP application that uses SNMP GETBULK requests to query a
32
network entity efficiently for a tree of information.
34
An object identifier (OID) may be given on the command line. This OID
35
specifies which portion of the object identifier space will be
36
searched using GETBULK requests. All variables in the subtree below
37
the given OID are queried and their values presented to the user.
38
Each variable name is given in the format specified in
40
If no OID argument is present,
44
If the network entity has an error processing the request packet, an
45
error packet will be returned and a message will be shown, helping to
46
pinpoint why the request was malformed.
48
If the tree search causes attempts to search beyond the end of the
49
MIB, the message "End of MIB" will be displayed.
53
Do not check whether the returned OIDs are increasing. Some agents
54
(LaserJets are an example) return OIDs out of order, but can
55
complete the walk anyway. Other agents return OIDs that are out of
58
to loop indefinitely. By default,
60
tries to detect this behavior and warns you when it hits an agent
63
to turn off this behaviour.
66
Include the given OID in the search range. Normally
68
uses GETBULK requests starting with the OID you specified and returns
69
all results in the MIB tree after that OID. Sometimes, you may wish
70
to include the OID specified on the command line in the printed
71
results if it is a valid OID in the tree itself. This option lets you
77
field in the GETBULK PDUs. This specifies the number of supplied
78
variables that should not be iterated over. The default is 0.
81
Upon completion of the walk, print the number of variables found.
86
field in the GETBULK PDUs. This specifies the maximum number of
87
iterations over the repeating variables. The default is 10.
89
In addition to these options,
91
takes the common options described in the
97
snmpbulkwalk -v2c -Os -c public zeus system
99
will retrieve all of the variables under system:
101
sysDescr.0 = STRING: "SunOS zeus.net.cmu.edu 4.1.3_U1 1 sun4m"
103
sysObjectID.0 = OID: enterprises.hp.nm.hpsystem.10.1.1
105
sysUpTime.0 = Timeticks: (155274552) 17 days, 23:19:05
107
sysContact.0 = STRING: ""
109
sysName.0 = STRING: "zeus.net.cmu.edu"
111
sysLocation.0 = STRING: ""
113
sysServices.0 = INTEGER: 72
117
this information will typically be gathered in a single transaction
118
with the agent, rather than one transaction per variable found.
120
is thus more efficient in terms of network utilisation, which may be
121
especially important when retrieving large tables.
125
utilizes the SNMP GETBULK message, which is not available in SNMP v1.
