SNMPWALK(1)                                       Net-SNMP                                       SNMPWALK(1)

NAME
       snmpwalk – communicates with a network entity using SNMP GETNEXT requests.

SYNOPSIS
       snmpwalk [APPLICATION OPTIONS] [COMMON OPTIONS] [OID]

DESCRIPTION
       snmpwalk  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 variables(5).

       If  no  OID argument is present, snmpwalk will search MIB-2.  If the network entity has an error pro-
       cessing the request packet, an error packet will be returned and a message will be shown, helping  to
       pinpoint why the request was malformed.

       If the tree search causes attempts to search beyond the end of the MIB, the message "End of MIB" will
       be displayed.

OPTIONS
       -Cc     Do not check whether the returned OIDs are increasing.  Some agents (LaserJets are  an  exam-
               ple)  return  OIDs  out of order, but can complete the walk anyway.  Other agents return OIDs
               that are out of order and can cause snmpwalk to  loop  indefinitely.   By  default,  snmpwalk
               tries  to detect this behavior and warns you when it hits an agent acting illegally.  Use -Cc
               to turn off this behaviour.

       -Ci     Include the given OID in the search range.  Normally snmpwalk uses GETNEXT requests  starting
               with  the  OID  you  specified and returns all results in the MIB tree after that OID.  Some-
               times, 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.

       -Cp     Upon completion of the walk, print the number of variables found.

       -Ct     Upon  completion of the walk, print the total wall-clock time it took to collect the data (in
               seconds).  Note that the timer is started just before  the  beginning  of  the  data  request
               series  and  stopped  just  after it finishes.  Most importantly, this means that it does not
               include snmp library initialization, shutdown, argument processing, and any other overhead.

       In addition to these options, snmpwalk takes the common options described in  the  snmpcmd(1)  manual
       page.

EXAMPLE
       The command:

       snmpwalk -Os -c public -v 1 zeus system

       will retrieve all of the variables under system:

       sysDescr.0 = STRING: "SunOS zeus.net.cmu.edu 4.1.3_U1 1 sun4m"
       sysObjectID.0 = OID: enterprises.hp.nm.hpsystem.10.1.1
       sysUpTime.0 = Timeticks: (155274552) 17 days, 23:19:05
       sysContact.0 = STRING: ""
       sysName.0 = STRING: "zeus.net.cmu.edu"
       sysLocation.0 = STRING: ""
       sysServices.0 = INTEGER: 72
