Network Management
In-band Network Management
You should also gauge the amount of traffic that is generated as the result of management traffic in
the network. This chapter provides some analyses on management traffic which can give the
network designer an idea if MOLN would be the choice for the transport medium for all
management traffic in a particular network. It many cases MOLN should not be used as the only
means of transporting management traffic in large complex networks. Figure 5-4 illustrates a
network of six Xedge nodes managed by MOLN.

Management via MOLN
The NMS can be connected to the network in one of three ways:
5-10
•
Ethernet interface
In this case an ETH or MS/QED Adaptation Controller must be installed in Slot-0 of the node
where the NMS connects. These controllers are capable of allowing one of the Ethernet streams
from an external interface to be bridged with the MOLN.
•
SLIP
This is configured in the switch and the connection is through the craft port. For SLIP
connection ensure that Pin 20 on DB25 connector (DTR) is low.
•
ATM
Another method for the NMS to connect to the network is to be connected using an ATM
connection, for which the workstation or external router, should have an ATM Network
Interface Card (NIC). This method is beyond the scope of this chapter and will not be described
in detail.
