FG – Fault Finding

I use the following commands on a daily basis to assist with fault finding:

Read the different log files in a browser. It’s easier and you sort and filter for info.

If it is a vdom enter the vdom.
diagnose debug config-error-log read
get sys startup-error-log
get sys arp
exec ping yyy.yyy.yyy.yyy

config vdom
edit xxxxxxxxx
dia debug reset
dia debug enable
dia debug console timestamp enable
dia debug flow filter vd xxx
dia debug flow filter saddr yyy.yyy.yyy.yyy
dia debug flow show console enable
dia debug flow show function-name enable
diag debug flow trace start yy

dia debug authd fsso server-status
diagnose debug authd fsso list
diagnose debug application authd 8256
diagnose debug application authd 0
dia debug authd fsso summary

dia snif pac zzz ‘host yyy.yyy.yyy.yyy’ 4
