Interpreting SNMP Parameters For High and Low Order Bytes

How should one interpret SNMP parameters , which are specified in low- and high order bytes.

These are in an NMS tool for displaying volSize used ( example volSizeLow and volSizeHigh ) .

I can't find a documentation about this within the SNMP-reference-guide.

There are various methods to combine low order bytes and high order bytes .

My perception is that these two 32bit counter should together form a 64-bit counter, but the method unclear.

Many thanks in advance.

Re: Interpreting SNMP Parameters For High and Low Order Bytes

Same question here

Max unsigned number that can be stored in 32bits counter is 4294967295.

Total size would be: LOW_ORDER_BYTES + HIGH_ORDER_BYTES * 4294967296

Total size in GB is LOW_ORDER_BYTES / 1073741824 + HIGH_ORDER_BYTES * 4 and the result is verified


In my monitoring i'll ignore the LOW_ORDER_BYTES and only use the HIGH_ORDER_BYTES which gives me the size with an accuracy of +/- 4 GB
