I have enabled syslog setting on my ASA 7.2
logging trap alerts
logging host inside x.x.x.x tcp/1468
logging facility 20
Whenever i enter logging facility 20 my syslog server starts receiving logs but stops after 15-20 min.
Also logging facility 20 does not appear in my running config.
Again if i enter the same command it starts working but again stops after 15 min.
