NAME
       snmpwalk	 -  retrieve a subtree of management values 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 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 net-
       work 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.

       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 example) 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 check.

       -CE {OID}
	       End  the	 walk  at the specified OID, rather than a simple sub-
	       tree.  This can be used to walk	a  partial  subtree,  selected
	       columns	of a table, or even two or more tables within a single
	       command.

       -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  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.

       -CI     In  fact,  the given OID will be retrieved automatically if the
	       main subtree walk returns no useable  values.   This  allows  a
	       walk  of a single instance to behave as generally expected, and
	       return the specified instance value.   This  option  turns  off
	       this  final  GET	 request,  so a walk of a single instance will
	       return nothing.

       -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.

EXAMPLES
       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
       (plus the contents of the sysORTable).

       The command:

       snmpwalk -Os -c public -v 1 -CE sysORTable zeus system

       will retrieve the scalar values, but omit the sysORTable.
