The Powerful Get-Next Operation

The "powerful get-next" is used to move from one object instance to the next in a managed node. For example:

get-next system.sysDescr.0

should return the lexicographically next instance in the MIB, thus:

sysObjectID.0

The operand of get-next need not be an instance specifier: it can be any OBJECT IDENTIFIER. Hence the call:

get-next system.sysDescr

returns the next instance, thus:

sysDescr.0

get-next can also take multiple operands, thus it is possible to use it to obtain multiple columns within a single row of a table of information in a single operation, eg:

get-next ipRouteDest, ipRouteIfindex

This is considered to be very useful, hence the terminology powerful get-next
