3.5.3 Management IP Address Configuration
Each Watson 5 Ethernet plugin 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 5 Ethernet plugin Figure 3-4.

Figure 3-17: IP networks for Management
In a Watson 5 Ethernet system where several plugin cards are installed in a subrack and where the
DSL links are also terminated with Watson 5 Ethernet plugin cards the following networks must be
configured:
! one network (Network A) for the Q – Interface on the front panel of the modem which is con-
nected to the management system
! one network (Network B) for the subrack connecting all backplane interfaces
! one network for all DSL links of a plugin. Within a subrack the DSL links of each plugin must be
in separate networks (Networks C, D in Figure 3-17)
The Watson 5 Ethernet tabletop modem does not have management routing functions. No network
has to be defined for DSL links that are terminate with the tabletop modem.
3.5.4 Management VLAN configuration
The Watson 5 Ethernet plugin modems support Ethernet inband management, i.e. it is possible to
manage the modems through the Ethernet user interfaces or through the Ethernet payload carried
over the DSL.
Ethernet inband management traffic is always routed through the internal management port
MGMT3 that connects the plugin controller to the Ethernet bridge.
To configure Ethernet inband management and to isolate management traffic from user traffic a
dedicated management VLAN has to be set up. By default the MGMT3 port is member of VLAN
4094, but it is possible to use a VID different from 4094 for management traffic.
