snmpwalk

communicates with a network entity using SNMP GETNEXT requests 

Command


SYNOPSIS

snmpwalk [APPLICATION_OPTIONS] [COMMON_OPTIONS] [OID]


DESCRIPTION

The snmpwalk utility 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 snmp_variables.

If no OID argument is present, snmpwalk will search MIB-2. 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.

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

Options

-Cc 

Does 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 behavior.

-Ci 

Includes 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. 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.

-Cp 

Upon completion of the walk, prints the number of variables found.

In addition to these options, snmpwalk takes the common options described in the snmpcmd reference page.


EXAMPLE

The command:

snmpwalk -Os -c public zeus system

will retrieve all of the variables under system:

sysDescr.0 = "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 = ""
sysName.0 = "zeus.net.cmu.edu"
sysLocation.0 = ""
sysServices.0 = 72

PORTABILITY

All UNIX systems. Windows XP. Windows Server 2003. Windows Vista. Windows 7. Windows Server 2008. Windows 8. Windows Server 2012.
