Cisco Support Logs

To capture support logs for a Cisco FC switch, following these instructions:

1) For firmware 1.2(x) and above telnet to the switch and open a capture session.
2) Run the following commands:
    term len 0
    show tech-support details
3) For firmware 1.0(4):  There is not a single command like a supportshow or data collection. There are two ways to get the outputs needed to troubleshoot most Cisco switch issues. Contact Lewan for additional information.

McDATA Switch Data Collection
