is an SNMP application that uses SNMP GETNEXT requests to query a
network entity for a tree of information.
An object identifier (OID) may be given on the command line. This OID
specifies which portion of the object identifier space will be
searched using GETNEXT requests. All variables in the subtree
below the given OID are queried and their values presented to the user.
Each variable name is given in the format specified in
If no OID argument is present,
will search the subtree rooted at SNMPv2-SMI::mib-2
(including any MIB object values from other MIB modules,
that are defined as lying within this subtree).
If the network entity has an error processing the request packet, an
error packet will be returned and a message will be shown, helping to
pinpoint why the request was malformed.

uses GETNEXT requests starting with the OID you specified and returns
all results in the MIB subtree rooted at that OID. Sometimes, you may
wish to include the OID specified on the command line in the printed
results if it is a valid OID in the tree itself. This option lets you
do this explicitly.
In addition to these options,
