Implementation Issues
SNMP implementations vary across platform vendors. In some cases, SNMP is an added feature, and is not taken seriously enough to be an element of the core design. Some major equipment vendors tend to over-extend their proprietary command line interface (CLI) centric configuration and control systems.
SNMP's seemingly simple tree structure and linear indexing may not always be understood well enough within the internal data structures that are elements of a platform's basic design. Consequently, processing SNMP queries on certain data sets may result in higher CPU utilization than necessary. One example of this would be large routing tables, such as BGP or IGP.

Famous quotes containing the word issues:
“Your toddler will be “good” if he feels like doing what you happen to want him to do and does not happen to feel like doing anything you would dislike. With a little cleverness you can organize life as a whole, and issues in particular, so that you both want the same thing most of the time.”
—Penelope Leach (20th century)
