Network Management Access
The EMM provides several ways to access network management. For
inband management, the EMM provides built-in SNMP (Simple Network
Management Protocol) agent, the de facto industry standard for network
management. The agent will let you manage EMMs through SNMP-based
network management solutions.
For out-of-band management, you can connect an ASCII terminal to the
RS-232 port on the module faceplate and manage the EMM using the
command-line interface. You also have the flexibility to use Telnet for
inband management using the same extensive command-line interface.
The EMM also provides the Remote_login and Telnet features.
Remote_login is based on the 3Com proprietary protocol, RCP (Remote
Character Protocol). Telnet support is based on a fully compliant TCP/IP
stack.
Network Management Functions
The EMM provides management and control capabilities in six major areas:
❑ Configurations - When logged in under the administrator password,
you can configure the EMM, Ethernet network, modules, ports, and
terminal settings.
❑ Fault, Performance, and Traffic Statistics Monitoring - Typical terminal
management systems only report statistics when you request them.
You can configure the EMM to continuously monitor and report key
statistics by invoking the MONITOR command. The statistics on the
screen are updated periodically to give a snapshot of the network.
❑ Security Control - The EMM provides two important security features
that prevent unauthorized access to devices on the network -
address-to-port security and a two-level password protection feature.
