New page

{{protocol|GETNEXT|utility=snmpgetnext|ref=3416}}

The '''GETNEXT''' command (GetnextRequest) requests a list of instances from a remote entity, but expects the '''next''' variable in the tree back. If a '''GETNEXT''' is issued on an object that does not exist, the agent MUST return the next instance in the [[MIB]] tree that does exist. If a '''GETNEXT''' is issued for an object that does exist, the agent must skip this entry and find the next instance in the MIB tree to return. If no more MIB objects exist in the MIB tree then an ''End of MIB'' exception is returned.

The expected returned [[PDU]] will be a [[RESPONSE]], although a [[REPORT]] may be issued as well in certain [[SNMPv3]] circumstances.

		+
		+	The [[snmpwalk]] application actually uses '''GETNEXT''' operations and continually asks for the ''next'' variable after the last one until it meets an end condition, which is either because it reached the end of the MIB tree or because the next [[OID]] returned was after the requested OID to be walked.
