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.
