RFC 5592         Secure Shell Transport Model for SNMP         June 2009

Abstract

   This memo describes a Transport Model for the Simple Network
   Management Protocol (SNMP), using the Secure Shell (SSH) protocol.

   This memo also defines a portion of the Management Information Base
   (MIB) for use with network management protocols in TCP/IP-based
   internets.  In particular, it defines objects for monitoring and
   managing the Secure Shell Transport Model for SNMP.
