Using the NMT
This chapter provides instructions for using the NMT interface, presents an overview of the modeling
process, and lists NMT commands that update or extract information from NMT configuration files. This
chapter contains the following sections:
• NMT Startup
• NMT Menu Bar
• File Menu
• Keyboard Commands
• Modeling Processes
• Error Checking
• Work Flow
The NMT models a network based on your input. Using your input about the network you want to model,
the NMT helps identify the hardware needed by provisioning the chassis with front cards and back cards.
The NMT routes the connections using the same software as the WAN switches, based on the Connection
Admission Control (CAC). The NMT is aware of all physical and logical constraints that would prevent
a connection or a trunk from being provisioned or routed. NMT is also aware of the different features
and constraints in each major switch software release.
Connection routing can be verified in the network's basic state. The connection re-routing can be verified
for any failure scenario. Simulation of failure of all network elements can verify the network's resiliency.
NMT Startup
If you are running NMT on a UNIX platform, start the NMT by entering the command nmt. This
launches an xterm window for the NMT interface (Figure 3-1).
If you are running NMT on a PC platform, start the NMT by clicking on the nmt.exe file located in the
NMT/bin subdirectory. This launches an xterm window for the NMT interface
