Snmpbulkwalk is an SNMP application that uses BULK Requests to query for a tree of information about a network entity.
A variable may also be given on the command line. This variable specifies which portion of the object identifier space will be searched using BULK Requests. All variables in the subtree below the given variable are queried as a single request and their values presented to the user. Each variable name is given in the format specified in variables(5)?.
snmpbulkwalk -v 2c zeus public system
will retrieve all of the variables under system:
system.sysDescr.0 = system.sysObjectID.0 = OID: enterprises.hp.nm.hpsystem.10.1.1 system.sysUpTime.0 = Timeticks: (155274552) 17 days, 23:19:05 system.sysContact.0 = system.sysName.0 = system.sysLocation.0 = system.sysServices.0 = 72
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, a message will be displayed:
