Hi Shelby,
Thanks! That's pretty useful. I also note that this same info is
available from the CLI, although I was curious as to what some of the
numbers indicated:
UP 0 years, 13 days, 19 hours, 25 minutes, 48 seconds, 887 milliseconds, 975 microseconds
529509 session(s) since startup
26 session(s) 0/30
1000 session(s) max
Specifically, 26 sessions 0/30... I take it this means there are 26
current sessions, but I'm unsure of what the "0/30" means.
