Figure 3-2 Logical Model for a NID
The forwarding plane is responsible for processing service frames exchanged between Client
and Network Ports, while the control plane is responsible for processing packets carrying
messages for administrative control of the 9145E along with synthetic test traffic generated by
the NID. A physical internal port provides connectivity between the forwarding and control
planes. The port that connects the control plane to the forwarding plane can have multiple logical
interfaces. For example, the management agent can be attached to this interface by assigning it
an IP Address. Likewise, the Test IP or Aux IP entities can present themselves on this interface
by enabling them on the NID and assigning them IP Addresses.
Manager This is the management entity of the NID. An IP Address can be user assigned
to the Manager. The Manager is responsible for peering a variety of
management protocols, such as TELNET, SNMP, SFTP and RADIUS, to name
a few. The Manager's IP Address is typically configured as an address on the
Service Provider's management network. The Manager will process any
packet received with this IP Address in the packet's destination address field.
Likewise, the Manager will generate IP packets with this address as its source
address field.
Test IP The Test IP entity generates and peers synthetic test traffic, such as Canoga
Perkins proprietary Latency/Jitter test traffic. The Test IP Address is user
configurable and the entity presents this address on the logical interface. The
Test IP entity will process any packet received with this IP Address in the
packet's destination address field. Likewise, the entity will generate IP packets
with this address as its source address field.
