1-24 Functional Description FCD-E1
The dedicated management traffic routers of the FCD-E1 systems, and of the other
RAD equipment, are able to determine network topology in accordance with the
capabilities of the routing algorithm, without requiring the user to provide a priori
topology information on the network. Moreover, the routing algorithm also supports
automatic switching to an alternate route in case the currently selected route fails.
The dedicated router operates on the inband traffic; the user can also enable the
routing of out-of-band traffic.
Combining Inband and Out-of-Band Management Capabilities
The advanced capabilities of the FCD-E1 SNMP agents allow easy integration of
the FCD-E1 system in wide-area managed communication systems. Its capabilities
support any practical communication network topology, as illustrated in the
example shown in Figure 1-8.
In Figure 1-8 the network management station attached to the FCD-E1 system can
manage, using inband communication over the user-selected links, all the units
(another FCD-E1 unit, and several Megaplex-2100 units), connected to the remote
ends of the corresponding links. Thus, an entire wide-area network can be
managed by means of a network management station connected to any FCD-E1
unit (or to any of the other RAD equipment, which supports SNMP management).
Remote Management using Telnet over IP
The FCD-E1 system supports the Telnet communication protocol, which enables any
IP host to access the FCD-E1 system supervision facility using TCP/IP
communication. The Telnet user has access to the same command-line interface that
is available to the user of a supervision terminal, however it uses the management
topologies described above for SNMP.
