Name Table Utility

Aname table provides associations between easy-to-remember symbolic names (Mickey) and hard-to-remember network addresses (0x78AB00004235).

Surveyor and Finisar analyzer devices learn names automatically by viewing the network portion of DNS, SAP, and NetBIOS packets. A default name table is supplied by Surveyor containing well-known name-to-address associations. You can change the default name table. A conversion utility (NIS-to-Name-Tableutility) is available to convert existing name tables into the name table format used by Surveyor.

Figure 13-1 on page 13-3 shows the Name Table dialog box. The name table contains three columns: Protocol, Name, Address. The 1st column contains the name of the Protocol that the address is associated with. The 2nd contains a name in the form of a character string that represents the address. The 3rd column contains the numeric address. Names can be associated with MAC, IP, IPX, or SNA addresses in a name table.

Name table data is presented as a table which can be sorted by clicking the column headers. Click and drag on column dividers to size columns.

The Name Table dialog box initially displays the default name table. You can manually add, modify, or delete name table entries. You can also change the active name table so that Surveyor will use a different name table file. You can create many name tables, but only one table is active at a time.

You can also let Surveyor learn names and addresses automatically from the network for MAC, IP, IPX, or SNA protocols. You can have Surveyor record all new addresses in the name table, or only those that have a corresponding symbolic name. Surveyor can capture name-address associations in real-time monitoring mode as well as capture mode. New names are added to the name table in monitor mode as they are discovered in the data stream. You must save any changes to the currently active name table in a name table file or changes will be lost when you exit Surveyor.
