Chapter 30: Troubleshooting
General Planning for Troubleshooting
Effective troubleshooting depends in part on measures that you take before you experience trouble
in your network. Cambium recommends the following measures for each site:
1. Identify troubleshooting tools that are available at your site (such as a protocol
analyzer).
2. Identify commands and other sources that can capture baseline data for the site.
These may include
◦ ping
◦ tracert or traceroute
◦ Link Capacity Test results
◦ throughput data
◦ Configuration tab captures
◦ Status tab captures
◦ session logs
3. Start a log for the site.
4. Include the following information in the log:
◦ operating procedures
◦ site-specific configuration records
◦ network topology
◦ software releases, boot versions, and FPGA firmware versions
◦ types of hardware deployed
◦ site-specific troubleshooting processes
◦ escalation procedures
5. Capture baseline data into the log from the sources listed in Step 2.
General Fault Isolation Process
Effective troubleshooting also requires an effective fault isolation methodology that includes
• attempting to isolate the problem to the level of a system, subsystem, or link, such as
o AP to SM
o AP to CMM
o AP to GPS
o CMM to GPS
