How To Collect Switch Information for Fibre Channel Environments


Sometimes Pure support needs to review switch data during performance troubleshooting. The majority of performance problems we've experienced have roots in the SAN topology, configuration, or due to degraded physical connections. Switch data is the most effective available tool for quickly ascertaining problem sources.


Both Brocade and Cisco require a ssh client with logging abilities. Here's how to collect that data on both Windows and a Mac:

Using putty on Windows

  1. Enter the IP or hostname of the Cisco or Brocade switch:
  2. Make sure logging is turned on for "All session output" and then save the resulting putty.log file to a location of your choice. It is helpful to make the log something relevant  unlike my example..:
  3. For Brocade run the command supportshow
  4. For Cisco run the command show tech-support details

For Mac Users

  1. Launch the application "Terminal" (depress the command key and the space bar to open Spotlight, type ter, and terminal will launch)
  2. SSH to your Brocade or Cisco switch. For Brocade run "supportshow" and for Cisco run "show tech-support"
  3. When the command completes, just save the text with ⌘S. Or go to the Shell menu and click "Export Text As.."
  4. Save it your desktop

When you have your putty log or your terminal text exported, zip it up and attach it to email. These are text files and almost always small enough to email.
If however you are unable to send it, ftp it to us using our anonymous ftp server:
Go into the "incoming" folder and upload it. Just let us know the filename you used.
