ADDING MAC ADDRESS VENDOR

TRANSLATIONS

3Com Network Director can convert the first six digits of a raw twelve

digit MAC address into a vendor name. You can enable this feature by

checking the Translate MACs option in the General tab of the Tools >

Options dialog box.

Network Director includes many hundreds of built-in translations, but you

can add your own or edit existing ones, by editing the file:

<Installation Directory>\MAC_Addr.txt

Network Director reads this file when it starts. If any errors are found then

an error is displayed, detailing the type and the location of the error in the

file, and the MAC address translations contained within the file are

ignored. Network Director reverts to a safe, backup copy of the originally

installed file until all errors have been corrected.

The format for the MAC_Addr.txt file is as follows:

Each MAC address translation must occupy a single line in the

file.

The format for each MAC address translation is:

where each field is separated by two or more consecutive spaces.
