Craft Interface
Ports
The Craft interface supports up to simultaneous sessions:
•
One direct local connection
•
Up to three Telnet sessions over Ethernet or SLIP. It is
recommended that only one Telnet session be used during
periods of heavy alarm activity.
Ethernet connectivity conforms to DIX and IEEE standards and is
supported through the AAUI connector port on the rear panel and a
provided transceiver with both 10BaseT and 10Base2 ports.
SNMP Support
The NCM supports SNMP-based clients such as Verilink’s Node
Manager and HP OpenView™, a Manager of Managers (MoMs), over
Ethernet or SLIP.
Adherence to ITU/ANSI/IETF specifications is required to ensure
compatibility and interoperability with complimentary SNMP
products. For more information on SNMP and Verilink products see
the SNMP Management Manual.
The NCM supports AS2000 node configuration by allowing
appropriate values to be assigned to and collected from the
configuration management objects defined in the supported MIBs.
Management application protocols such as Node Manager make use
of the MIBs.
The NCM 2000 does not support MIB II.
