Troubleshooting Numbers for Ethernet
What are the troubleshooting numbers?
The Ethernet troubleshooting numbers are lists of Type codes, vendor
codes, LSAP codes, multicast addresses, etc. that can help identify
and track down machines and protocols in use on the network.
For example, the vendor codes make it possible to identify the
manufacturer of a given Ethernet card. That can help you find out
which machine on your network may be causing problems, by identifying
the vendor of the Ethernet interface in the machine.
Locally Stored Copies:
Note! The locally stored copies are kept here to provide
access when the network path to online copies is slow or down. The
locally stored copies are out of date.
This page provides access to various troubleshooting numbers for
Ethernet. These numbers include Type codes, vendor codes,
LSAP/DSAP numbers, and multicast addresses.
If your Web browser supports a search feature, you can use it to
search through these lists for a specific Type code, vendor code, or
address.
Online Access:
Online access is provided to download the latest copies. Be advised
that FTP access may fail due to limits on the number of simultaneous
users allowed at anonymous FTP servers.
