Abstract The Simple Network Management Protocol (SNMP) and the Internet Standard Management Framework are widely used for the management of communication devices, creating a need to specify SNMP access (including access to SNMP MIB object instances) from non-SNMP management environments. For example, when out-of-band IP management is used via a separate management interface (e.g., for a device that does not support in-band IP access), a uniform way to indicate how to contact the device for management is needed. Uniform Resource Identifiers (URIs) fit this need well, as they allow a single text string to indicate a management access communication endpoint for a wide variety of IP-based protocols. This document defines a URI scheme so that SNMP can be designated as the protocol used for management. The scheme also allows a URI to designate one or more MIB object instances. Black, et al.

Registration Template................................ 17 1. Introduction SNMP and the Internet-Standard Management Framework were originally devised to manage IP devices via in-band means, in which management access is primarily via the same interface(s) used to send and receive IP traffic. SNMP's wide adoption has resulted in its use for managing communication devices that do not support in-band IP access (e.g., Fibre Channel devices); a separate out-of-band IP interface is often used for management. URIs provide a convenient way to locate that interface and specify the protocol to be used for management; one possible scenario is for an in-band query to return a URI that indicates how the device is managed. This document specifies a URI scheme to permit SNMP (including a specific SNMP context) to be designated as the management protocol by such a URI. This scheme also allows a URI to refer to specific object instances within an SNMP MIB.
