DTM Configuration

Overview of DTM configuration

This chapter describes how to use the web interface to configure monitor the
DTM-layer. The start web page for DTM is shown in the, Figure 64, below.

Figure 64. The start web page for DTM

The sub-sections are:

•

Interfaces: monitor the state of the DTM interfaces and configure the
interfaces present in the unit.

•

Addresses: configure the DTM addresses of the unit.

•

Host names: configure mapping between the host names and the DTM
addresses.

•

Links: show the state of the DTM links to other units. The page can be
used to check if the links to the surrounding nodes have been properly
established.

•

Routing: monitors and configures the DTM routing.

•

Sync: monitor the synchronization status of the node and modify the
external clock.

Note:

Make sure to have all the information that the operation
requires, before starting any configuration operationThis will
help you to minimize any downtime of the system.
