The major features of the EMM include:
❑ Telnet support for remotely managing the EMM via inband
connection
❑ Inband network management via SNMP for local and remote
configuration capabilities for all concentrators in the network.
❑ Out-of-band network management via an RS-232 terminal connection
for local and remote configuration capabilities for all concentrators
on the network
❑ Dynamic network control and management to the module and port
level
❑ Flash PROM designed for quick upgrade to the newest version of
software using inband or out-of-band downloads
❑ Automatic detection of faults and failures
❑ Security features to prevent unauthorized use
❑ Continuous monitoring and reporting of key network statistics
❑ Support of the 3Com TriChannel Architecture, ONdemand
Port-Switching, and fault tolerance capabilities
