Title: Mostly competent but pretty confusing
Review: Black does a reasonably good job of selecting relevant content, but reading this book is difficult. There are numerous typos - some of them in crucial diagrams - and the writing style is dense and unclear, often leaving you pondering a sentence for hours because you feel that it's important but have no idea what it means. A much better resource for this subject is Stallings, "SNMP, SNMPv2, and CMIP: The Practical Guide to Network-Management Standards". Unfortunately, that is out of print, and I don't know if Stallings has superseded it with any of his numerous other books.
