Workaround

The workaround is to disable Tacacs level 6 tracing on agent Aaa. switch(config)# no trace Aaa enable Tacacs levels 6 Clean Up Existing Log Files If any of the above agent logging levels have been enabled, it’s necessary to clean up the existing log files to remove the already leaked secrets and keys. Use the following commands to clean up Aaa or ConfigAgent log files: switch(config)# bash sudo truncate -s 0 /var/log/agents/Aaa* switch(config)# bash sudo truncate -s 0 /var/log/agents/ConfigAgent*   Then use the following commands to clean up previously rotated old log files: switch(config)# bash sudo find /var/log/agents -name 'Aaa*.gz' -type f -delete switch(config)# bash sudo find /var/log/agents -name 'ConfigAgent*.gz' -type f -delete
