Configuration Tables and Fields

This appendix describes the fields in tables accessed through the Configure menu. The following legend refers to the Notes column. Refer to this legend when deciding whether to edit an NMT default value.

• M--Mandatory. If you are revising this table, you must revise this field.

• E--Evaluate. If you are revising this table, you should consider revising this field. For instance, this field may require modification if you are working with a tiered network, an ISP, a network that requires highly regulated bandwidth, or one in which cost factors must be highly regulated.

• O--Optional. If you are revising this table, you need not revise this field. Defaults are generally suitable.

• P--Parts. Required for generating an accurate parts list.

• H--Help. Press F12 or the Help key to call up a list of choices.

• X--Entries generated by the NMT that cannot be edited.

An asterisk in the Configuration Extraction Tool (CET) column or the Third Party Interface (TPI) column indicates that application supports a particular field. For instance, the CET extracts site names from the StrataView Plus database, so there is an asterisk in the site row of the CET column.
