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: () 17 days, 23:19:05

sysContact.0 = STRING: “”

sysName.0 = STRING: “zeus.net.cmu.edu”

sysLocation.0 = STRING: “”

sysServices.0 = INTEGER: 72
