Cabletron Systems ESXMIM Benutzerhandbuch

 

Introduction

 

The management agent is a process within the ESXMIM which collects 
statistical information (e.g., frames received, errors detected) about the 
managed network’s operational performance. Local Management 
communicates with the management agent for the purpose of viewing 
statistics or issuing management commands.

 

Network management systems are often classified as either in-band or 
out-of-band. In-band network management passes data along the same 
medium (cables, frequencies) used by all other stations on the network. 
An example of an in-band network management system is Cabletron 
Systems SPECTRUM.

Out-of-band network management passes data along a medium that is 
entirely separate from the network’s common data carrier, for example, a 
cable connection between a dumb terminal and the ESXMIM’s COM 
port. Cabletron Systems Local Management is an out-of-band network 
management system. 

A device connected out-of-band to the management agent is not 
connected to the LAN. This type of connection allows you to 
communicate with a network device even when that device is unable to 
communicate through the network, for example, at the time of 
installation.

 

Network management applications are usually described as either local or 
remote management applications. Local management applications reside 
within the management device’s management agent. Remote 
management applications run within the circuits of another device that 
provides management services. This allows you to perform network 
management from a remote location.
