Normally snmpget is used to get value of one OID. It is possible to get values of a number of OIDs,but writing the OIDs is cumbersome. Especially when values of related OIDs are read, it is better to use snmpgetnext
snmpget 100.100.100.3 -v1 -On -cpublic .1.3.6.1.2.1.4.1.0 .1.3.6.1.2.1.4.2.0
.1.3.6.1.2.1.4.1.0 = INTEGER: forwarding(1)
.1.3.6.1.2.1.4.2.0 = INTEGER: 255

snmpgetnext returns the value of next OID
snmpgetnext 100.100.100.3 -v1 -On -cpublic .1.3.6.1.2.1.4.1.0
.1.3.6.1.2.1.4.2.0 = INTEGER: 255

Of course it is possible to use multiple OIDs with snmpgetnext
snmpgetnext 100.100.100.3 -v1 -On -cpublic .1.3.6.1.2.1.4.1.0 .1.3.6.1.2.1.4.6.0
.1.3.6.1.2.1.4.2.0 = INTEGER: 255
.1.3.6.1.2.1.4.7.0 = Counter32: 0

From this it is obvious that snmpgetnext can be usd to walk through a sequence of values. Incidentally, this is one of the few cases in which it is OK to omit the trailing 0. This command can be particularly helpful if you don't know the next identifier
snmpgetnext 100.100.100.3 -v1 -On -cpublic .1.3.6.1.2.1.4.1 .1.3.6.1.2.1.4.6
.1.3.6.1.2.1.4.1.0 = INTEGER: forwarding(1)
.1.3.6.1.2.1.4.6.0 = Counter32: 686327

snmpgetnext 100.100.100.3 -v1 -On -cpublic .1.3.6.1.2.1.2.2.1.10 .1.3.6.1.2.1.2.2.1.16
.1.3.6.1.2.1.2.2.1.10.1 = Counter32: 454
.1.3.6.1.2.1.2.2.1.16.1 = Counter32: 546
