A.3 Collecting Additional Information

Once basic adapter installation and network connectivity have been tested, this section explains how to obtain all of the additional information that you need to have ready before calling Cabletron Systems Technical Support. This information should exist either on-line (by redirecting the output to a file) or in hard copy form.

A.3.1 Basic Information

The following basic network information is very useful in helping Cabletron Systems’ Technical Support staff troubleshoot your problem:

1.Host platform configuration

•Vendor name

•Platform type

•RAM (MB)

•Disk drive size (approximate)

2.Patches installed (very important for SunOS and Solaris)

3.Network topology (physical configuration)

•Sketch and FAX in, if possible

Please have your support contract ID number and serial number ready, also.

A.3.2 Adapter Information

On the host, at a command line, type the following six commands and note the responses:

•uname -a(Shows operating system, and platform names and ver- sions)

•ifconfig fa0 (Shows adapter interface configuration)

•netstat -nr(Shows routing table with destinations, gateways, and flags)

•netstat -in(Shows device names and addresses, and usage informa- tion)

•adinfo fa0 (Shows adapter device name and version information)

•atmstat -d fa0 (Shows carrier state and a variety of error counters)

Typical responses are shown under each command. The responses from these commands enable support to gather sufficient information to resolve the majority of problems.
