3.5.3 Management IP Address Configuration
Each Watson Ethernet plug-in contains a management router that connects
three networks:
 one network at the Q – Interface (MGMT1) on the front panel of the modem
 one network at the backplane interface (MGMT2) on the subrack
SZ.379.V3W
 one network at the internal interface (MGMT3) connecting to the Ethernet
bridge
Cf. the block diagram of the Watson Ethernet plug-in Figure 3-4.
Figure 3-18: IP networks for Management
In a Watson Ethernet system where several plug-in cards are installed in a sub-
rack and where the DSL spans are also terminated with Watson Ethernet plug-in
cards the following subnetworks must be configured:
 one subnetwork (Network A) for the Q – Interface on the front panel of the
modem which is connected to the management system
 one subnetwork (Network B) for the subrack connecting all backplane inter-
faces
 one subnetwork for all DSL spans of a plug-in. Within a subrack the DSL
spans of each plug-in must be in separate subnetworks (Networks C, D in
Figure 3-18)
The Watson Ethernet tabletop modem does not have management routing func-
tions. No subnetwork has to be defined for DSL spans that are terminated with
the tabletop modem.
