How to collect support logs from Cisco MDS 9000 series switches
Cause
Cisco switch logs are needed when there is an issue with Cisco switch itself or if there are SAN related issues.
Answer
To collect logs from Cisco switches you have two options. You can download a utility that will collect logs automatically or you can collect the logs manually.
Automatic Log Collection:
Manual Log Collection:
Watch this short video to see the data collection process or review the steps listed after the video:
Configure your telnet or ssh application (example PuTTY) to log the screen output to a text file.
Baseline data collection for all types of problems - these two commands should be run for every problem
Baseline data collection for all types of problems - these two commands should be run for every problem
Connect to the switch and run these commands:
# term length 0
# show logging onboard
# exit
Save the file and then change the file name and run these commands:
# term length 0 (this command allows the text output to scroll)
# show tech-support details
# exit
# show tech-support details
# exit
In addition to the baseline data, other data might be needed for different issues.
Data for issues with port stability or link problems
Change your screen output file name and run these commands:
# term length 0
#show interface transceiver details
#exit
Data to be collected if the issue is related to performance within the local SAN
Change your screen output file name and run these commands:
# term length 0
#show hardware internal statistics device fabric errors
#exit
Data for long distance FCIP (Fibre Channel over IP) replication issues
# term length 0
# show tech-support fcip
# exit
Collect one show tech-support details per switch and name the file uniquely:
[switchname]_showtech_YYYYMMDD_hhmm.txt
Example: ibmsw_showtech_20160421_1030.txt
ibmsw_showlogging_20160421_1030.txt
ibmsw_hardwareinternal_20160421_1030.txt
ibmsw_transceiver_20160421_1030.txt
Collect logs from all the switches in your fabric one by one or from the switches in question.

Collect logs from all the switches in your fabric one by one or from the switches in question.
Compress all files collected into a single compressed file, such as showtech_20220115_1030.zip.
Upload the file to IBM under your ticket number:

Error counters on a switch are cumulative. It is a good practice to clear the statistics on a switch after collecting logs, then collect another set of logs once the problem happens again, or a few hours later if it is an ongoing problem.
Run these commands to clear the statistics on switch:
#clear counters interface all - this command clears the port counters.
#debug system internal clear-counters all - this command clears the ASIC counters.
#clear ips stats all - this command clears FCIP counters and is only needed on FCIP enabled switches.
