21 Snmpwalk is an SNMP application that uses GET NEXT Requests
22 to query for a tree of information about a network
23 entity.
24
25
26 A variable may also be given on the command line. This
27 variable specifies which portion of the object identifier
28 space will be searched using GET NEXT Requests. All
29 variables in the subtree below the given variable are
30 queried and their values presented to the user. Each
31 variable name is given in the format specified in
32 variables(5).

51 enterprises.hp.nm.hpsystem.10.1.1

60 If the network entity has an error processing the request
61 packet, an error packet will be returned and a message will
62 be shown, helping to pinpoint why the request was
63 malformed.

66 If the tree search causes attempts to search beyond the end

68

70 ''End of MIB.''

82 Includes the requested oid in the search range. Normally
83 snmpwalk uses getnexts starting with the oid you request and
84 returns all results in the MIB tree below the one you
85 requested. Sometimes, you may wish to include the OID
86 specified on the command line in the printed results if it
87 is a valid OID in the tree itself. This option lets you do
88 this.

101 Don't Check whether the returned OID's are increasing. Some
2 perry 102 agents (!LaserJets are an example) returns OID's out of
1 perry 103 order, but can complete the walk anyway. Other agent's
104 return OIDs that are out of order and can cause snmpwalk to
105 loop infinitely until stopped. By default, snmpwalk tries to
106 detect this behavior and warns you when it hits an agent
107 acting illegally. Use -Cc to turn off this
108 behavior.
